I used it on my previous Powerbook 12" and very happy about it

i don't think it works on newer Intel-based (especially Core2Duo) Macbook Pro

anyone knows an alternative solution to it?

for those who never use FastAndSlow
it reduces the speed manually on menubar , so i don't have to run the fastest speed all the time, and i don't like how OSX handles dynamic processor speed adjustment

thanks in advanced

What do you mean you "don't like how OSX handles dynamic processor speed adjustment?" What bothers you about it? I've never heard of this program (and don't see it on VT), but with the switch to Intel, I doubt there is any way for developers to make processor speed changes as they could in the old days (OS 9 to early OS X).

one of the reason i would like to adjust the speed of my Macbook Pro is the heat issue

i prefer to use lower speed & lower voltage while just surfing the web

it's on Macupdate:
FastAndSlow 1.3.1 - MacUpdate

The Intel chips/chipsets have more advanced power managment, and will slow down to use the minimum number of cores, clockrate, and voltage (although there is a clockrate floor around 800Mhz with a corresponding low voltage) to complete the current workload. So when you're browsing the web it will be at 1 core and 800Mhz for simple pages, although flash will cause it to speed up due to the CPU use issues there.

I don't think there's really any advantage to be had by forcing a clockrate/voltage ceiling manually.

i prefer controlling it manually

i don't mind to run stuff bit slower but with lower voltage (for cooling purpose)
