Try git pull and make then make load. I've pushed update that should make it work fine on 32-bit SL 10.6.

Hi Adam,

I've added Github to my Macbook and succeeded in pulling DisableTurboBoost.kext.

Unfortunately I still don't know how I should be using "make" and "makeload". Here are the errors I get:

ak15:~ alec$ make /Users/alec/github/local/DisableTurboBoost.kext
make: Nothing to be done for /Users/alec/github/local/DisableTurboBoost.kext'. ak15:~ alec$ make /Users/alec/github/local/DisableTurboBoost.kext/Makefile make: Nothing to be done for/Users/alec/github/local/DisableTurboBoost.kext/Makefile'.

Could you make your instructions a bit more explicit? I'm a user interface designer and not a programmer.

Thanks!

Alec

PS. Double thanks for the quick update of the code.

First make to compile then make load to load the extension and disable Turbo Boost. You shouldn't put any extra argument such as path of project to make, but your current directory should be DisableTurboBoost.kext.

make load will ask for your password as it requires admin access to load kernel extension. Anytime you want bring Turbo Boost back you do make unload.

Please note that this extension is not production quality, but that wasn't my goal. So for example it does not disable TB after you wake your Mac after sleep, so you need to make unload & make load again.

Hi Adam,

Thanks very much for the more detailed instructions. I've successfully loaded DisableTurboBoost.kext. While setting Fan Speed at 3000 or 3600 as a baseline with iStatMenus, there seems to be much less tendency while browsing intensively or doing light photo editing for the fans to jump up to 4000+ where they make a racket.

As you know boosting processor speed even a little bit massively increases power consumption and temperature. This is fantastic, as I work in very quiet conditions and I've had a slow hate for this i7 MacBook Pro.

Where DisableTurboBoost.kext helps most is when a few websites run away with Safari 5.05 and peg Safari alone at 99% (single threaded).

I'll let you know how it goes over the next week or so. If DisableTurboBoost.kext works as well as it seems, then it might very well be worthwhile creating a production version.

Cordial regards,

Alec

Hi Adam,

Is there anyway to enhance the functionality of DisableTurboBoost to slightly under clock the i7?

That would bring temperatures down even further and result in even less fan noise.

There appears to be something called TDP Power Limit Override which might allow us to throttle the processor earlier. There's also something called Maximum Non-Turbo Ratio.

Making the web work for you, Alec
