An update after WWDC 2020

Hi there!!

Edit (11/11/2020): Keeps working fine with Big Sur Release Candidate 2!

Go for 2.10.0 version now!

Be warned: Big Sur is beta and can contain bugs preventing the app to work.., so proceed of course at your own risk! That being said…

Ready for some good news!? Yeah! I’ve just tested Turbo Boost Switcher, both free and PRO with macOS Big Sur first developer beta and it works as expected.., this is the first time since Sierra the app works with the first beta release, so that’s really great!

The only thing that seems to be changed regarding install procedure (in fact, it did for all apps using kernel extensions) is that after installing a reboot is mandatory.

App working fine with RC2 (hopefully final version) of Big Sur

I spent some time testing and all features seem to work just fine (notifications, auto modes, disabling and enabling, monitoring, etc), but of course this is just the first beta release of macOS Big Sur so stay tuned!

Another interesting thing is that on this version Apple finally added a way to easily rebuild kext collections and ask for user approval again… so, if you missed it and/or the kext seems to not be loading, follow the steps provided by Apple and:

  1. Boot to macOS Recovery.
  2. Run Terminal.
  3. Enter the command kmutil trigger-panic-medic --volume-root /Volumes/<YourVolumeName>.
  4. Restart your Mac.

Next time you’ll try to load a kext.., that is, Disable Turbo Boost, the system will ask for user approval again at Security & Privacy screen and you’ll need to reboot again.

As always, will keep the blog updated if needed and after testing the app against betas as they come out.

Of course, Big Sur is in beta yet, and the same Apple recommends, I suggest not to try this on your daily Mac since it contain bugs.., still a lot in fact regarding kext processing… and the app can even not work depending on your configuration, different bugs that can be present, etc…, but in any case, this seems promising!

Thanks and enjoy!

    Nice, I was worried about updating to Big Sur as I am mostly dependent on TBS.
