just found this one at apple discussions
http://discussions.apple.com/thread.jsp ... 7&tstart=0

thanks!

okay well i think i've got it. but im unsure how safe it is.
it turns out if you just delete the kernel extension titled "IOPlatformPluginFamily.kext" that is mentioned in the discussions.apple.com thread (located in: System -> Library -> Extensions -> IOPlatformPluginFamily.kext),
the throttling stops, and you can repair permissions/reboot and the throttling will still stay off.
Now, i dunno what other stuff is in that kernel extension, but i've been running pretty solidly without it.. opened and tested all my apps and plug-ins and so far so good.
i'll keep you posted, but this looks like the fix.
just to be safe: backup all your data before you do this.
and also backup the .kext file that you are deleting.

well guys i think deleting that .kext kernel extension is indeed the fix.
for one thing, this kernel extension is not on my iMac G5's system library, so i don't think it can be THAT vital.
i just put my macbook pro through its paces for an hour, with the kernel extension deleted.
running 32 applications, simultaneously. notably: the live performance test with some WaveArts AU's and ableton reverbs stacked on..
the big lebowsky on DVD player, and every other app in my applications folder.
it didnt break a sweat. Menu Meters never showed more than 70% per core, and i used about 1GB of ram. It was like driving your car at 90mph for the first time.

Have you noticed significantly less battery life or any heat issues with this change?AdamJay wrote:well guys i think deleting that .kext kernel extension is indeed the fix.

I can't help but wonder why the people at apple didn't think to just remove this file in the first place if it's not necessary.

Possibly to introduce an OS upgrade and claim increase in speed (due to the upgrade)?glitchrock-buddha wrote:Have you noticed significantly less battery life or any heat issues with this change?AdamJay wrote:well guys i think deleting that .kext kernel extension is indeed the fix.
