TBS – New Version – 2.12.0

Hello there!

Here comes again a new version of Turbo Boost Switcher both FREE & PRO to celebrate incoming macOS Ventura version just released.

This time all new features are requested by many of you since a lot of time!

  • macOS Ventura tested and ready to go! (FREE and PRO)
  • New Auto Mode: CPU Load (PRO only): Yes! now you can set a CPU level as auto mode. As you can see in the following figure, enable it so Turbo Boost is automatically disabled when cpu load goes above the configured level, and goes on again below a certain load.
  • Revamped Charting!: (FREE and PRO): Charting needed some love since long ago, so put some work over them with this version:

    • 2 New Chart Modes: Now you can view also the CPU Load and Frequency average values.
    • No data: When there is no data available a gray background layer is added.
    • Adjusted charts: Axes and values are now scaled proportionally.
    • CPU Frequency Charts: Since retrieving CPU frequency (using powermetrics) is time and cpu consuming, data is only obtained when charting window is open, that’s why no value is shown (grey background) when charting is closed.
  • Minor fixes and improvements, help update and so on.

So hope you enjoy it! and please let me know what you think about this new version on comments below.

Thanks for your help and support!!!

TBS working on macOS Ventura

Hi there!

I’ve just tried myself and wanted to share with all of you that Turbo Boost Switcher (both PRO and FREE versions) is working flawlessly on the just released macOS Ventura final!

Hooray! I’ll keep this post updated after each beta release until final version for compatibility tracking. That means the app is compatible with macOS 13 final version!

Here you’ve got a little screenshot taken just now

And there is more… since Power Mode Switcher is working just fine too!

For those of you that need to approve the kernel extension again and/or installing for the first time on macOS Ventura, the process is the same, but Apple changed the user interface a little.

Here is how it’s shown as of now. As you can see, now settings are shown with a left navigation sidebar, but you just need to click there over “Security and privacy” as always and, after that, click over “Details…” in order to enable the kernel extension from “Legacy Developer: rugarciap”. Something like the following screenshots. After that, remember to reboot! although macOS will ask you to do that.

Click over Details under Privacy & Security
Enable Turbo Boost kernel extension and finally reboot. Done!


TBS – New Version – 2.11.0

Hello there!

Here comes a new release of Turbo Boost Switcher, version 2.11.0. It’s already available for download both free and pro version.

I’ve been waiting for Monterey to become final to be sure it’s fully compatible without any issues, and since even previous version worked just fine, here we go!

Let’s get into it and take a deeper look to the new features it includes:

  • Auto mode priorities! (PRO): As many of you have requested, now you can change auto mode tabs position to decide which configuration is reviewed first!. Just do some drag & drop after clicking on new “Reorder” button to decide which auto mode is evaluated first.
  • Custom Hotkeys (FREE & PRO): This is another feature requested by many of you!. Now you can set your own hotkeys both for disabling / enabling Turbo Boost and charting
  • Ability to enable / disable hotkeys: … and if you want to just disable hotkeys, feel free to do it with the new hotkeys configuration window.
  • Several other minor improvements and new features, like:
    • Fan auto mode now up to 8.000rpm
    • Modal popups are now always on top modal
    • Translation improvements
    • … and more!

Hopes you like it and as always thank you very much for your support!

TBS on Monterey working!

Hi there!

That’s it… I’ve been testing the app with Monterey and works just fine from beta to final vresion! Hurray! As you can see on the image below, the app keeps disabling turbo boost with Monterey developer beta final! .All other features works fine the same that they do on current stable Big Sur version.

And there is MORE. I’ve been playing with the new low power mode provided by Apple in Monterey, and it does NOT disables Turbo Boost. Instead, it keeps the frecuency above the base clock value (in mine, 300Mhz above) so the power & battery saving and temperature reduction is still better if you use Turbo Boost Switcher than Low Power Mode from Apple.

Best of all, you can use both! I tried Since that feature is a little obscure, and they might be performing other optimisations.., it’s great that you can have both options to keep disabling turbo boost and get other improvements by Apple itself on their new low power mode option.

This was just a little fast test… and of course more time is needed, but the first results on my test Macbook Pro (characteristics on previous figure) seems to point that.

  • Turbo Boost Switcher saves you 4Watts compared to new Low Power Mode.
  • Turbo Boost Switcher will lower down the frequency 300Mhz below Low Power Mode does.
  • Turbo Boost Swithcer gets you lower temperature, 5ºC less than Low Power Mode.

Of course, this numbers may change depending on the Mac model you’re working with, but the relative difference between those configurations will probably be proportional. Apple did some job here finally, but it seems that at least for now Turbo Boost Switcher will get you better battery performance, temperature and noise reduction that the new low power mode. Let’s see in the future!


TBS – New Version – 2.10.0

Hi there!

It’s been a lot! but ey, Turbo Boost Switcher is available on its 2.10.0 version containing some new interesting features I think you’ll enjoy.

A couple of them in fact were requested by many of you:

  • New temperature auto mode (for PRO version only)
  • Global hotkeys so you can enable / disable Turbo Boost at will without removing your hands from keyboard 🙂
  • Translation improvements.
  • Stability and energy efficiency improvements, a must with Big Sur.
  • Some other minor issues fixed.

This update is recommended for everyone.

Thanks for spreading the word! Enjoy!

TBS – New update – 2.7.1


Here comes a new update of Turbo Boost Switcher, both free and pro versions. This is just a minor update containing some little fixes with no additional features:

  • Fixed an issue about fan speeds that affects only to new Macbooks Pro 2018.  New macbooks (2018 pro ones) return fan speed using different data type, so this is just a little update to display the fan readings.  In any case, remember that under 1000 rpm aprox. the readings return “0” value, so N/A will continue to be displayed whenever the fans are not running.
  • Remember refresh rate setting (this is just for free version, pro was working fine).
  • Charting compatibility with OSX 10.8 fixed, since some users reported the new Charts feature introduced on 2.7.0 were not showing properly on Mac OSX 10.8.
  • Updated app signature to my Developer ID certificate, so no more warnings about “unidentified” developer are shown when installing.
  • Other minor fixes (translations, status update timing adjustment, etc).

To update, just download the corresponding file and install as usual. More info on how to update.


Turbo Boost Switcher on Mojave and Macbook 2018

Hi there!

In summary, yes, the app works fine, both free and pro, with latest Mojave Beta and also the new Macbooks Pro 2018. Just writing this small post to let you all know :).

Mojave first betas suffered from one bug that was preventing the kernel extension from being loaded. That affected to many apps like Littlesnitch, but after reporting to Apple, they solved it on public beta 3 of Mojave (developer beta 4) :), so yes, the app is again working just fine with latest Mojave Beta!

Here you’ve got a screenshot of the app running on my MB air with Mojave public beta 3 and dark mode enabled.

About the app running on new Macbooks (2018), it just works fine allowing to enable / disable turbo boost without issues. It makes sense, since as you know (you should! :P) the feature is controlled by a Processor MSRs and Intel doesn’t change that from model to model… (the feature depends on Intel, not Apple….). There has been also many users confirmations of the app running on new Macbook, so, again, yes, the app works fine with the new MBPs 2018 so far.

Edit: Confirmed myself with my new MBP 2018 and little fixed released on 2.7.1 version.

As always, thanks for all your comments and support!

TBS – New Version 2.7.0 released!


I’m back again to publish a new release of Turbo Boost Switcher… 2.7.0.

2.7.0 PRO version screenshot

  • FREE & PRO: Long requested ability from many of you of changing the sensors refresh/update time. Default value is 4 seconds and you’ll be able to change it from 1 to 60.

  • Only PRO: Alerts! Notifications have been moved to customizable “Alerts” based on Temperature, Fan speed, etc… and one more thing. If Turbo Boost feature is enabled, you will be able to disable it directly from the alert popup.
  • FREE & PRO: Some minor bugfixes and translations.

As always, thanks for your comments and support!

TBS: New Version in progress

Hi there!

It’s been some time since my last post… oops :P. Christmas, Holidays, kids..,

Just writing to let you all know that I’ve just started the development for the next version of Turbo Boost Switcher, both PRO and FREE version.

I’ve got some ideas, like adding a Today Widget to the Notifications Bar (to display some charts to show the impact of the app, etc), customize the status bar refresh time as some of you’ve requested.., and other improvements.

If you’ve got any requests / ideas you’d like to discuss/see in the next (or future) versions, feel free to comment below ;).

As always, thanks for your support and feedback.


TBS – New Version released!

Hi again!

Glad to announce that here comes a new update of Turbo Boost Switcher, both free and pro versions.

This release includes several features requested by many of you:

2.- [FREE & PRO]: Automatically restart the app when changing language to directly apply the new setting.

4.- [FREE & PRO]: As many of you also have requested, new icon for off state, so you can check Turbo Boost status even when there is anything else on the status bar (just take a look at the screenshot above).

5.- [PRO]: Improved auto battery configuration, so you can set both battery level and charger connected settings at the same time.

6.- [FREE & PRO]: Minor changes like removing the enable / disable icon to prevent confusions, menu items sorting, minor bugs fixed and improvements, etc.

So hope you like it and as always thanks for your support and feedback.

Enjoy 🙂

Edit (04/10/2017): Just released a little fix only needed on the FREE version, since it was refreshing the data on screen too fast.., went back to every 4 seconds. Go here to download the upgrade if you want 😉
