Underclock Mac

How to underclock a Mac running OS X 10.8.2?

Macs do not run at full CPU usage the whole time, modern Intel CPUs are quite at throttling themselves.

Why do you want to do it in the first place?

[Intell]

It's still running within Intell's specifications. If is was running "way too hot" it would shutdown to prevent damage.

That doesn't work with 10.7+.

It does.

It does.

Then your machine has a defect. Take it to Apple to have it serviced.

Even if that does get it working, it still isn't a good idea to use an outdated and already unstable kernel extension with an OS that it does not support.

Just use SMCFanControl to make your fans run at a bit higher rpm.
