Issue: Turbo boost cannot be enabled back #186

Closed black-balamut closed 1 year ago

Ventura 13.0 Macbook pro 16 2019, i7-9750H I installed the app (Turbo_Boost_Switcher_v2.12.0) according to the guide and disabled turbo boost - everything was fine. But when I toggle it back to enabled - nothing happens. The CPU frequency is always a maximum of 2.6 ghz (monitoring via intel power gadget), and my CPU has never more heated to 100C. I tried reinstalling app, completely uninstalling, cleaning kextcache, and resetting smc/nvram/pram, million rebooting - nothing helped. There is no loaded DisableTurboBoost.64bits.kext, but Turboboost is still not working.

Hello,

This is not an issue with the app neither the kext. Turbo Boost setting is volatile, in fact, once you turn off your computer it gets enabled again, no matter if you keep the app running or not. It's at MSR register level (CPU level).

Remember that since macOS Monterey, a feature called Low Power Mode is available, and macOS (if that is turn on, by default it is), limits your CPU frequency too. You can configure that from control panel, battery settings.. and using "pmset -g" at terminal you will display lowpowermode status.

In order to get the max cpu frequency you'll need to disable also low power mode. You can use another tool also I've created called Power Mode Switcher (www.pmswitcher.com) .

You can take a look to this too: https://www.rugarciap.com/2021/07/tbs-on-monterey-beta-working/

Best!
