What others say:

“I noticed nearly an hour increase in potential battery life when using the app to toggle Turbo Boost off on a new model MacBook Pro” (OSXDaily)

The MacBook Pro also runs noticeably cooler, and gains about 25% more battery life“, “For now, I’m going to continue to happily run Turbo Boost Switcher Pro to selectively give myself better battery life, and I recommend it for anyone else with the same need.” (marco.org)

“En mis pruebas, logré obtener entre un 25 a 30% extra de duración de batería…” (arturogoga.com)

OSX 10.6+ compatible up to Big Sur  ¿Installing for the first time on a machine and with macOS High Sierra/Mojave/Catalina/Big Sur installed? Read this first.

Looking about how to update? Read more here. Any additional doubts and/or problems when running/installing? Read the FAQs here.


Turbo Boost Switcher is a little application for Mac computers that allows to enable and/or disable the Turbo Boost feature.

It installs a precompiled kernel extension (32 or 64 bits depending on your system) that updates the Turbo Boost MSR register, so It will ask for your admin password when using it.

It’s installed on your Mac status bar and allows you to:

  • Languages: English, Spanish, Chinese (beta), Russian (beta), German (beta), Polish (beta), French (beta), Swedish (beta), Czech (beta), Italian (beta).
  • macOS Mojave ready with full dark mode support.
  • Visually know if Turbo Boost is enabled or disabled at any time.
  • Enable / Disable Turbo Boost manually, getting up to a 25% more battery life and lowering down the CPU Temp up to 20ºC. (check this).
  • Fan and Temperature charts.
  • Configure it to disable Turbo Boost automatically at launch.
  • Enable / Disable Turbo Boost automatically for a set of apps (only on Pro version).
  • Set default mode for Turbo Boost Enabled or not (On or Off)
  • Disable Turbo Boost when battery charger is not connected (only on Pro version).
  • Disable Turbo Boost depending on fan speed (only on Pro version).
  • Disable Turbo Boost depending on temperature (only on Pro version).
  • Disable Turbo Boost depending on remaining battery time (only on Pro version).
  • Disable Turbo Boost automatically when battery goes below a configurable level (only on Pro version).
  • OSX Notifications/Alerts integration (only on Pro version).
  • Asks for root password only once (only on Pro version).
  • Status Bar configurable.
  • Status Bar fully configurable (Temperature, fans, cpu load, etc, only on Pro version).
  • Display CPU Load
  • Check your CPU temp and fan speed.
  • Display temps in ºC and ºF (only on Pro version).
  • Set it to open at login.
  • Automatically restore Turbo Boost on exit.

Here you have a couple of additional screenshots (PRO version):

How to install:

 Get the Pro version here to help keeping alive this project :).

You can also download a free binary application or the source code to compile it with XCode.

Once downloaded/compiled, just unzip (or open the .dmg if using PRO). Drag the .app to your Applications folder (this is a must on any version equal to Sierra or above) and double click on the App. An icon like the next one will appear on your status bar.

If you see a message saying the app “can’t be opened because it is from an identified developer”, then you need to change your settings to allow not-signed apps to be installed. Go to your System Preferences->Security and Privacy and mark the option “Anyhwere”. Try again, it should work.

Also, and just if you’re running for the first time on a machine with macOS High Sierra or above installed, you’ll need to allow the kernel extension to be used the first time you try to disable Turbo Boost.

Just go to System Preferences -> Security and Privacy and click “allow” after trying to disable Turbo Boost for first time. You can read more about this here.

From Mojave 10.14.5 and also in Catalina, a reboot may be needed just after this. No worries, macOS will ask you to do that if you need to do so, but just in case, remember rebooting after authorising the kext to run.

Apple is also providing detailed info about this here. Below a couple of screenshots of the process.


Turbo Boost is enabled by default on all Macs that support it, but why anyone should want to disable it?

Ok, here are some reasons:

  • CPU Overheat: When Turbo Boost is activated, prepare to experiment high temperatures on your CPU, since it pushes till it reaches almost the Junction Tº, usually 100 ºC. This is controlled by hardware, but if you want your computer to live long, better keep it as low as possible. With Turbo Boost disabled I’ve been able to get up to 20 ºC degrees less!!!, that’s a value worth considering.
  • Parallel Processing: Turbo Boost is activated (by Intel® internal algorithms) when one of the CPU cores reaches 100%, increasing the core Mhz, but It won’t do it if all or your cores are 100%, since that will create a lot of overheat. This will reduce your parallel processing performance so, in some situations, you better disable it.

If you are like me, you probably do some high cpu demanding tasks from time to time, like photoshop editing, video transcoding, casual gaming, etc. and your fans go to max speeds while your CPU keeps crazy ranges like 93 – 98 ºC.

I’ve started to look for applications, and the only thing I found was this cool kernel extension https://github.com/nanoant/DisableTurboBoost.kext created by “nanoant”. This is a very simple extension that manipulates the MSR record writing the Turbo Boost flag.

If you don’t want to always be opening your terminal, compile the code, make sure you don’t forget to re-enable it, etc. then Turbo Boost Switcher is for you.

How to know if Turbo Boost is enabled (or not):

To see the differences between having Turbo Boost enabled or not, you can do the following tasks:

  • Install smcFanControl, a cool app that will help you to set your fan speeds to desired values.
  • The simplest one, do some high demanding gaming with Turbo Boost enabled and disabled, checking the CPU temperature values and see the differences.
  • You can also launch some long time high demanding tasks, like the Geekbench benchmarks app. You’ll get a lower value since Turbo Boost will not be triggered. On my Macbook Air I go from 7500 to 4000 points aprox. with Turbo Boost disabled.
  • Open a terminal and execute “kextstat”. If you see a line including “com.rugarciap.DisableTurboBoost” that means Turbo Boost is disabled.
  • Check the MSR register for yourself (0x1a0), but that could be tricky and we’re not going to go deeper here.

    Silencing the fan of Macbook is what I was looking for. This does it!

    It didn’t come in my mind for long time that solution for silence would be to disable turboboost, and that it is possible.

    I just was looking ways to silence the fan or to affect fan speed, or ways to effect processor time given to processes that devour processor power. No working solution was found even though tried some fan speed apps.

    You should add in the main benefits also gettin Macbook silent again and my kind of silence loving people can also find Turbo Boost Switcher.

    Especially powerful Macbooks with i7 and i9 processor get very loud as they age. There is lot of power available and it’s devoured by a variety of background processes you cant’ affect to, which leads to annoying fan noise and hot laptop at your lap. This made my Macbook silent and cool again.

    Suprising is also that you can’t even notice effect of missing Turboboost in normal usage.


  2. Ted Bahas says:

    I bought the Pro version right away after seeing a review on YouTube. I bought a 16″ I9 MacBook Pro and almost immediately regretted it because of the constant fan noise. Eventhough the process was only at about 8% the fan was acting like I was hitting the processor hard. Once I installed the Pro version it has worked like a charm. I usually leave it off unless I am doing music production or Photo editing. Great app and easy documentation. Good work!

  3. Vlad says:

    It’s sad that we have to go and install different apps to get rid of different annoying stuff when we pay a lot of money for these products. Frankly I came across your app by mistake. I was searching for another problem (how to fix severe scrolling stutter in safari or other browesers).
    Great app, easy to use, bought the pro version after using for 10 hours the free version.
    Keep up the good work.

  4. Flint says:

    I purchased a MacBook Pro 2.0 ghz model a couple of months ago and I immediately noticed the heat it generated while in use. I tried to ignore it but it bothered me to the point that I was on the verge of trading it in for one the M1 based Macs. Coming from the PC world I remembered that I can disable Turbo boost in the bios of some pcs and started my research of a feature like that possible for Macs. Thats when I can across this app and purchased the Pro version after an hour use of the free version.

    • Jtbayes says:

      Awesome app, brought the pro version last month for Macbook Air 2020 i5 model, was initially really disappointed with apple/intel for there turbo boost/thermal management. Consistent 100c temps and v high fan speed.

      This app helps solve this, quieter, better battery and cooler system. Thanks you

  5. Ron Michael Zettlemoyer says:

    Turbo Boost Switcher has been fantastic for me. One thing that would make it significantly better is a quick way to temporarily turn off turbo boost. I usually leave it on automatic. To turn boost off, I have to disable automatic mode and then disable the boost. It’d be neat if there was a one click way to turn off boost and maybe have it go back to automatic in an hour or some customizable time frame.

  6. Michael says:


    Am a Pro user and love it. Is the app compatible with Big Sur? I see it uses a kernel extension and believe those aren’t allowed anymore.


    • rugarciap says:

      Yes it is! kexts are allowed in Big Sur.., only those with support on system extensions framework are deprecated, and that’s not the case of the one used by this app :). You can read the blog posts to see that in fact the app works with Big Sur even since the first release of the beta version. Best!

  7. Sergey says:

    I am really enjoying a Pro version of your app on Intel based MacBook, but i wonder if your your app will work on Macs with Apple’s new own M1 chip… Can you share thoughts on the matter?

  8. Kelton says:

    Congratulations on the app, I bought a license for your software (pro version) because it really solves the problem of my macbook air core i5 model 2020. It easily reached 98 degrees celsius! Now I have activated the auto mode option and for the app to manage alone, when it reaches 3000 rpm it automatically disables the turbo boost of my machine, that is, it does not exceed more than 60 degrees celsius.
    I would like to leave a suggestion only, if it were possible to choose the icons for activating and deactivating the turbo boost, it would be something interesting, where the user could customize and choose the activated and deactivated icons, among those offered by the app itself.

    Congratulations again

  9. GW says:

    One question – if I quit Turbo Boost Switcher Pro does the Mac go back to it’s own default automatic mode of switching Turbo boost on/off ? Or, perhaps, is it always on or always off depending on the last state of TB Switcher Pro App ? Thanks.

    • rugarciap says:


      Yes it does.., when you quit the app Turbo Boost status comes back to default state being controlled exclusively by macOS and the CPU itself.


  10. indi says:

    this app is a life-saver/job-saver amazing! THANK YOU.

    If anyone in the pro audio world is experiencing pops or clicks in their audio recordings, even with a $3k interface, or any interface for that matter, it’s most likely Mac’s Turbo Boost to blame. the fluctuating clock speed of the computers processor (turbo boost) makes having a master clock nearly pointless.

    id go as far to say one should use this app when recording audio whether or not they’re having audible recording fidelity issues… crazy to be bottlenecked against your expensive gear.

    THANK YOU rugarciap!!

  11. Isa says:

    Macbook Air i5 2020. The machine stayed at 100% longer than usual, even the fan is stopped with CPU temp at 48 degree (C). I bought pro license right away. Good job and thanks!

  12. Christopher Selph says:

    My favorite app! Had to support and get the pro version and I recommend it to all of my friends and family members.

  13. Shaun Parfett says:

    Ruben, you have made me very happy with your free version, so I bought the Pro version, which makes me even happier. I received a new i7 Mac Mini a couple of days ago and the fan noise was driving me mad. I was extremely disappointed with my purchase as a result – I was really looking forward to the new kit.

    Some Googling brought me to your product, which has solved my problem, and without any noticeable decrease in performance. Absolutely brilliant app. To anyone thinking of buying the Pro version, just do it. The additional features such as auto disabling of Turbo Boost based on criteria you set is very useful. The ability to see the temp on the menu bar is great. This just works. I can stay on Zoom calls without the fan noise driving me insane.

    Many, many thanks. Great job.

  14. Keith F. says:

    My wife does a lot of video calls these days for work and was about to give up on her 2020 MacBook Air because of the fan noise while using Zoom. I installed the pro version of this, set it to auto (based on fan speed) and it works like a charm. Great product, thanks!

  15. Hồ Nguyên Lý says:

    Nice app, I bought the Pro Version and absolutely love it!!

  16. Thank you so much, awesome piece of software!

  17. M.Moosa says:

    One of the best apps for maintaining your mac’s sanity. I am very impressed by their app and their customer service is of top-notch quality and leaves you satisfied.
    100% Recommend this app :)))

  18. barey says:

    I am interested in this but I have some personal concerns. For example, if in the future I choose that I do not want tbs anymore, does the kernel extension get removed and my Mac reverts back to how it was before tbs?

    • rugarciap says:

      Hi! Yes, the kext is loaded at runtime only, not installed permanently on the system…, so if you quit the app and/or drag it to trash, the kext will run no more. Best!

  19. Matthias says:

    In April I bought my first MacBook and it felt like I had just been drawn back to what I came from: my old Windows based notebook suffered from regular overheating and throttling disturbances.

    I kind of felt from the beginning on that my MacBook cpu’s base clock was somewhat enough for everything I wanted to do. It kept me irritated that, when playing simple browser games or using office apps, the fans were launched to blow my hair away.

    Now I am just amazed and while using Turbo Boost Switcher Pro for nearly a month – I bought it immediately upon reading about it – my MacBook fan nightmare has evolved to the MacBook dream story I was hoping to experience.

    You have turned an expensive hairdryer into the working machine I wanted. ¡Muchas gracias!

    • rugarciap says:

      Thanks to you for supporting! 🙂

    • Satoshi Nakamoto says:

      Its insane that Apple is not providing a proper solution for this. TurboBoost Switcher works so great and silently you instantly miss it when its gone. I had my MacBook Pro 2018 repaired and it got returned with clean install.. took me two days to figure out what was missing… i almost forgot i had been using TurboBoost Switcher… immediately got the paid version this time 🙂

  20. Damian O. says:

    I use it on the Macbook Pro 16″, and it works great with SketchUp image rendering. TBS keeps my temp from spiking, and I use it in conjunction with Macs Fan Control to make sure my max temp doesn’t get above 75C or so.

    Nice work and thanks for the awesome app.

    Long live our processors!

  21. Richard says:

    I am so happy that I found this app (credit to the Max Tech video I found on YouTube). My MacBook Pro 16″ was constantly in TurboBoost mode due to a couple of programs I use all the time plus the 2 x 4k displays that I use when I am in my home office. So far all of my running programs and displays work just as well when the TurboBoost is turned off and my MacBook Pro is running much cooler. Thank you for developing the app – I am glad I went for the Pro version. I am also runnig TG Pro and the temperatures across the board (pun intended) are much lower and I can now hear myself think at my desk.

  22. Matt says:

    Great piece of software. My new MacBook Air 2020 runs much cooler, quieter and for longer (battery) since disabling turbo boost. The computer is still snappy, and I am thankful that my laptop does not sound like it is about to take off every time I run an old game, or an IDE.
    Thank you!

  23. Gephard says:

    Great Tool, can’t live without it anymore. 😉

    Here some suggestions for future updates:
    – Add an option to show the power usage in Watts (like iStat Menus)
    – Add graphs/statistics for power usage
    – Enhance the automation to react to power consumption in Watts
    – Show a list of power eating processes

  24. Andy says:

    This is an incredibly useful app. I have been tearing my hair out for weeks what to do about my old MacBook Air that was sounding like a leaf blower during the frequent zoom video conference meetings that I have to do now. Even worse, whatever new fancy laptop I considered, the reviews all complain that they either get hot, or their fans get loud with the new high performance, high heat-generating processors they use.
    This app solves my noise problem with zoom (and similar problem with Microsoft Outlook and OneDrive). I checked, and the battery life is also significantly increased (doubled from 40 minutes to 80 on this old machine). I also realized that even if I buy a new computer I will most likely have to underclock them occasionally.

  25. Robin says:

    You’re a lifesaver! I was about to throw my Mac away.. For 1 year it has been slow as sh**! Now it run smooth as ever!!

  26. Philippe says:

    I used it with Folding@home, because I didn’t want to burn the CPU on my MacBook Air. 😅 It’s a very useful app!

  27. Jeff Diamond says:

    Thank you so, so much! My 2015 Macbook Pro is FINALLY truly silent! This is such an amazing feature! I look forwards to this app enabling me to use a 2016 MBP in the near future, as I was holding off buying one until the fan noise issues could be ironed out. 🙂

    – Jeff

  28. Aleksandr says:

    Awesome. It works well with my Macbook Pro 16″. OS Catalina 10.15.3.
    Must have!

  29. Anthony says:

    Thanks for this great tool ! Perfect on my macbook pro 15″ 2018 i7 2,6Ghz 32gb ram.

    Just a (simple) question : i don’t understand the “refresh rate”. It’s just to check if TB is enabled ? what’s the impact of 4sec or 60sec ?

    Thank you !

  30. Roger Fonts says:

    That’s a great app! Yesterday I bought and tried the pro version with my MBP 16″. Estimated battery life, which appears in activity monitor as around 10h when using 50% brightness and only safari and listening to music through headphones, changed instantly to 20:00h. I couldn’t believe it!!! I worked a bit in these conditions and the estimated battery life was still 19h after half an hour working. I try to use battery the less I can but now it will be much better. Thanks 🙂

  31. Chris says:

    Thanks for this great idea.

    I recently moved away from my MacBook 12, which by design slowed down the CPU if needed to not overheat. And it also doesn’t have a fan, which keeps the machine quiet. I loved the machine for that.

    With my new MacBook Pro, I am happy to now have the same option through your little app. Because in 95% of the cases, I rather wait a few second longer (i.e. exporting a video) than having a noisy machine howling on my desk.

    Thank you

  32. said says:

    thank you Ray,

    This is an amazing app. I am using an external display with my mbp15 2019 and because it uses the dGPU, the CPU was always in turbo boost mode (Just doing regular development work as I was doing with the mbp13 2011). Less noise and cooler.

    Will buy the pro version soon. Keep up the good work.

  33. Defxx says:

    Realy nice and easy to use program. It would be even better if you can enable/disable TB depending on CPU temperature. Would love to see this in a future update.

  34. Andy says:

    I’ve been using the older version of Turbo Boost Switcher and I just updated to the latest Pro edition. I am running OSX El Capitan 10.11.6 and there were no problems for me, just quit the old one and then copied the new version into the Applications folder.

    Really pleased with the Pro version! I’ve set it up so that on mains power, Turbo Boost is enabled, and on battery power, Turbo Boost is off. This is what Apple should have allowed in the OS. Initial observations are that the Mac runs much cooler and I believe the battery time is improved. Plus I don’t have to enter passwords any more. Good job.

  35. Phil S says:

    Guys, this is an amazing little app and idea. I work with Avid Pro Tools (digital audio) and we’ve been experiencing numerous critical and soul-crushing CPU spikes for months and months with no resolution (or comprehension, frankly) from the manufacturer. I read about your app on a user forum and it has instantly stopped the problem. Amazing! The audio and digital markets are full of users with these problems, I urge you to get the word out!

  36. danny says:

    This app works like a charm on my macbook pro. Most off the time i dont need full power such as browsing on the internet etc.. Thanks for the great application.

  37. Isac says:

    Thanks for a really awesome app! I recently bought the paid version and it’s great to have the auto abilities!

    I mainly have issues with the fan making a lot of noise when I use heavy apps, for example running VMs, on my 2018 MBP i7 2.7. Setting Turbo Boost auto Off when the VM starts is a great feature and makes my MBP dead silent again.

    I would like to request a feature to have automatic Enable/Disable of Turbo Boost then the fan reaches a specified threshold. That would be a great addition and would make my MBP always silent 🙂

    Thanks again!

  38. Nicolas says:


    My MacBook Pro 2018 core I7 2,7 Ghz become very (very) hot and noisy during app development. I have tested Turbo Boost Switcher and the difference is awesome!

    Building an iOS app using Xcode with Turbo Boost the cpu reach 100°c and the fans are very (very) noisy.

    Making same app without Turbo Boost, the cpu do not exceed 80°c and fans are totally inaudible.

    With Turbo Boost the job take 1″30 versus 1″50 without. Compare to the comfort of a MacBook Pro quiet and at normal temperature the result of my test is 100% positive.

    You have accomplish a great job!

    I will purchased the version Pro without hesitation.


  39. Ryan says:

    Awesome app! Dropped my CPU temp by 30 degrees. Thank you!

  40. RW says:

    Bought the Pro version for my 2018 Macbook Pro (which has a meh battery life). Love to support independent devs making AWESOME tools.

  41. Tommy says:

    Just bought the Pro version.
    Fantastic product.

  42. Nick says:

    Magic! I bought pro immediately, this tool massively improves my macbook.

    I use a 2017 Macbook Pro 13 nTB, with the i7. This thing overheats like crazy during regular work days, and the single fan goes crazy. Apple already replaced parts, but otherwise said “Macbooks just get hot”.

    Since using this tool, the system keeps cool and rarely needs to use the fan anymore. Fantastic! I can visibly see the difference on the real-time charts.


  43. Turbo Boost Switcher along with the computer grounded to a power strip from Supra (with filtration & is shielded) is my best solution to reduce electromagnetic field around my workspace. With turbo boost off, the spikes on the mains are reduced to a minimum which has as much effect as the grounding. Hope this software also will support boost for GPU in the future.

  44. Xavier says:

    WOW! been on the free version, bought the pro version today. ❤️ it.

  45. Daniel says:

    Thank you so much for the app. I was looking into undervolting my CPU but it was a PITA as I didn’t want to disable SIP so just disabling TB was the second best option and yours has been working as expected.

    I’m trying the trial version to ensure everything is OK and will purchase the pro version if I notice no issues. Thanks again for your awesome work.

  46. Mikael says:

    Thanks for the app.
    I use the pro version. I use it cool down my MacBook Pro when using Chromecast. Using Chromecast will trigger hyper boost and set the speed fans to high speed. It seems like your app did the trick and lowered the temperatures about 10-20 degrees celsius.

  47. Christopher says:

    A GREAT Idea and another example of a small ISV seeing an Issue and Providing the Solution! No “Big” company would never build something like this so Thank You and Long Live the ISV.

    My Question:
    Reading your description it sounds like if the Mac is in TurboBoost mode ONLY 1 Core is Active?

    Did I read that correctly?

    If only 1 Core is Active in TurboBoost mode multicore applications will only use the 1 Core correct?

    Thank You,


  48. Mark says:

    Can you make a version that turns off speedstep (CPU throttling below base frequency)? macOS doesn’t allow this and I suspect some of the glitching in my real-time audio setup comes from this. (In Windows, it is common to advise turning this off with pro audio applications.) NB: I have a very high-spec system and push it very hard.

    Actually the more control over the CPU freq/voltage settings the better. For example, I would love to test my setup with a completely fixed CPU freq to see how much glitching comes from CPU state transitions.

    • rugarciap says:

      Thanks for your feedback! That’s a great idea :), but since TBS is built around Turbo boost feature, it would be some kind of redundant to include same features for speedstep…, I’m working around some ideas for a new app and this definitely would fit better on that one. Stay tuned and thanks again! 😉

  49. Great tool, thank you!

    I´ve noticed the “beta” on german localization but still would like to add my 2ct: “Exit Turbo Boost Switcher” is wrongly translated into “Ausfahrt … ” and should read “Turbo Boost Switcher verlassen”.

  50. Paul Lambertson says:

    This is an awesome addition to Mac OS Sierra. I’m currently using the free version, I want to try it out. So far it is beyond expectation. It has integrated perfectly with Sierra 10.12. Thanks for creating Turbo Boost switcher. I definitely plan on purchasing pro version soon.

  51. Alex says:

    Hello, thanks for this app, it works great on Sierra.
    I tried it a while ago and was glad I found it again on an old backup, I prefer a cooler CPU and better battery life since I have no need for heavy and hungry apps.
    Just bought the Pro for support 😉

    I’ve got a suggestion for the next version, do you think you could offer an option to hide the menubar icon? We could access the settings again by “relaunching” the app, it’s what the BetterTouchTool dev are doing and it works great for people who don’t want to tinker with the settings often !

  52. Azad Damsaz says:

    Woooow! This app alleviates the aches on my top fingers! Also my battery length time has significantly increased! ! 10/10 !! This works great on my 10.12.2 beta 1 mac OS Sierra on my macbook pro 13 (mid 2012). Cheers!

    I have a pro licence how do I download the new update 2.2

    • rugarciap says:

      Hi! Just enter Gumroad and download the latest version using your email. You can check your email too, you should have received an email when the update was released on August.

      Best regards!

  54. Marek_Vienna says:

    I have a question. When I want to uninstall this application, stay the turbo boost status automaticaly enabled ? Thank you for support !

    • rugarciap says:


      If you mean when you “Quit the app” then yes, the Turbo Boost feature is enabled again when you click on “Quit”. If you mean “what happens when I delete the app”.., just make sure you quit the app before deleting it.

      In any case, after removing the app, and if you want to make sure, just reboot and Turbo Boost feature will be enabled again. Check the FAQs for more info.

      Best regards.

    Amazing app! Thanks for all of your hard work! My MBP 15 is now running cool!


  61. MightyCat_ says:

    I own the 1st rMBP (with the highest CPU config – 2.7G CPU) and I’ve been always having issues with high temp. I need CPU on full force only occasionally and when the tboost is off the temp is lower by 10stC .. I’ll continue using it!

  62. boehli says:

    There’s still a trouble with the “On/Off” status in the bar. Sometimes it doesn’t show the good status, the more when “disable at launch” is set.

    This app is a must have ! thanks !

    Is it possible to have an option for Turbo Boost “re-enabled” when the battery charger is connected (i.e. the dual of the current “Disabled when charger disconnected”)?

    Other than that, the app is awesome! I love the pro version you just released adding the option for the OTP (one-time password)! I was using the free version beforehand, but the pro version is 100% worth the $10. I appreciate your work 🙂

    • rugarciap says:

      Thanks! Maybe in the future, but it could be a bit “confusing” if you combine that with auto configuration based on apps running… will see 😉

      • Adrian says:

        Fair enough!

        However, I am having trouble with the auto mode. When I add a process to the list and try to change the “Enable/Disable” parameter by double clicking and typing “Enable” (and seeing the text change from “Disable” to “Enable”) it doesn’t seem to stick. I cannot get it to change from “Disable” to “Enable”. Am I doing something wrong?

    Just become root or choose an user with Admin permissions

    • roberto says:

      it does not work it always ask for password

      • rugarciap says:

        It works…, asking for root password is normal since that’s needed to install the kernel extension that disables Turbo Boost.

        Just use sudo. Open a terminal and write (replacing the path with the corresponding one where you installed the app)

        $sudo ./Turbo\ Boost\ Switcher\ Pro.app/Contents/Mac/Turbo\ Boost\ Switcher\ Pro

        That will run the app with root permissions

      I am already Admin, and it doesn’t work : password window everytime…

      • rugarciap says:

        Just use sudo. Open a terminal and write (replacing the path with the corresponding one where you installed the app)

        $sudo ./Turbo\ Boost\ Switcher\ Pro.app/Contents/Mac/Turbo\ Boost\ Switcher\ Pro

        That will run the app with root permissions

  66. Can says:


    do you plan to have a signed version of the app ? 🙂

    it’s seem to be mandatory for the kext with OS X 10.11 El Capitan.


  67. Chris says:

    Finally a replacement for CoolBook!! Thank you for programming this awesome app, supported you by buying the Pro version.
    What do you think about implementing a feature to turn Turbo off when CPU reaches a certain heat?

  68. Tom says:

    Hi, thanks for the extension! It keeps asking me for admin password after wakeup from sleep. how can i fix this? thanks!

  69. Phil says:

    Is there a way to give this app explicit root-rights? It’s painful to always grand root-privileges.

  70. OP says:

    Hi, very useful app, but I have a comment on Automode: Wouldn’t it make sense to rather ENABLE turbo boost when certain apps are running, rather than DISABLING? Or have the option for both? At least for me, I would want to have turbo mode disabled by default, but enable it when using certain apps (which is why I bought the pro version..)

    I also second the suggestion in an earlier comment to use power source to enable/disable turbo boost.

  71. Ziyang says:

    Hi, thank you for this awesome app.

    I bought the Pro version thought there will be an auto mode to enable Turbo Boost when power adapter is plugged. But there is not.

    Would you add this in next version?

    • rugarciap says:

      Great idea, thanks! I’ll consider it for sure 😉

      • ctrl alt dileep says:

        Thanks for the free version. The paid version doesn’t make much sense to me. I’d gladly pay for a version that disables turbo when the machine is running on battery.

      • danilo says:

        Hi Rugarciap 🙂

        For me your app is “essential” and never know that a pro version exist…

        i want to buy it… but now i have another Macbook “Macbook Pro Retina 15 mid 2015 WITHOUT DEDICATED GPU” only the intel gpu and Iris Graphics.

        On this machine your app don’t work :(…. when i click on “disable” nothing happens and on “console” have only this output

        20/04/16 00:20:48,071 Turbo Boost Switcher[1369]: kextstat output: (null)
        20/04/16 00:20:48,086 authexec[1404]: executing /usr/sbin/chown

        🙁 🙁 🙁 :(…

        I privately pay you to fix this on my machine …

        please let me how i can contact you .. and if possible i want to buy the complete Pro version with this fix.

        thanks .

        • danilo says:

          Sorry Rugarciap…

          it’s a my mistake…

          in short a “permission” problem occurs in my case…

          i have set the correct permission “copied from another machine via BatChMod utility” set the exactly same permission and WORKS!!!

          OK , now.. i want the Pro Version… where i can buy it ?… Guarantee me that you implement some new feature like the suggested from other users as soon as possible ?.

          thanks you.. 😀

        • rugarciap says:

          That’s strange… , it seems kextstat is not working, and that’s an utility provided by OSX.

          Try opening a terminal and running “kextstat -v” and, if that command doesn’t show results, try with “sudo kextstat -v”.

          This command displays kernel extensions installed, and by the log you posted it seems it isn’t working

    Hey, is it possible to get the Pro Edition via Paypal?

  73. Joseph Foreman says:

    Just wanted to say thanks a lot for making this feature available to the masses.

    I’ve been tearing my hair out trying to come up with a cooling solution when rendering on my i7 3770 imac. Even with custom fan profiles I was regularly hitting 90C + which is not great for overnight renders.

    I just did a quick test on a small render and the difference was about 14C cooler (using TG Pro to measure) with turbo boost off and only lost about 7% overall render time. That’s a win in my books. Kudos to you and whoever wrote the original script.

    Thanks again!

    Please, be aware that using Ray’s version can cause the app to display wrong temperature measures depending on the Mac model you’re using.

    I’ll release a new version very soon with this fixed.


  75. Ray says:

    Hi, I just modified some code from the origin code, and I known the reason why the console print this error.But I can not explain this in English, sorry.
    You can checkout my fork at GitHub.Here is the url:https://github.com/wr1241/Turbo-Boost-Switcher/commit/207ff7d61a2f1031d810092d1774954097ca4011

    I love this software!

    • rugarciap says:

      Thank you Ray!

      I’m also aware of the problem, it’s just these days it’s impossible for me to release a new version, but I will do it as soon as I can.

      Thanks again!


    • rugarciap says:

      By the way, just reviewed your code and have some comments 🙂

      You changed it to use always the same sensor. That will work on a reduced set of laptos, but not on all Macs.

      The real problem is to always try to read from the sensors array, instead of storing the correct one for future reads. This was fixed on previous version, but storing the right sensor on NSUserDefaults. The right solution is to use the same sensor per session, without storing it on NSUserDefaults, that will force to use the same sensor forever.

      As I told on previous post, I will release a new version as soon as I can with this little fix.
