I am having trouble with some processed which hog up all the CPU power such as flash.

Is there a GUI app which can limit how much each process can use the CPU? I know you can do this via command line, but I would like something more user friendly.

Freezer. Thanks to beiju for finding these for his own answer.

I'm running snow leopard, all those mentioned are either very very very old and do not specify support, or say they don't support. –  cappuccino Nov 29 '10 at 5:44
    
The publisher of Freezer commented on that page that Snow Leopard is supported. I tested it on SL just now and it seems to work fine. –  Stephen Jennings Nov 29 '10 at 5:47
    
Freezer does not allow me to 'limit' how much a process takes from the CPU. It only allows me to pause, and change priority, but not set for example 10% for a particular process. Also it only lists the opened applications, it does not allow me to target for example 'Flash Player (Safari Internet plug-in), and other background processes. –  cappuccino Nov 29 '10 at 5:51
    
I see. I didn't know such a thing was possible. For my own knowledge, what command line does that (you referred to it in the question)? –  Stephen Jennings Nov 29 '10 at 5:53
    
I tried the apps you suggested, but they made no difference on CPU usage. Command line that does such (I think): cpulimit.sourceforge.net –  cappuccino Nov 29 '10 at 5:58
