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.

  • 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. Nov 29, 2010 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.

  • 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)? Nov 29, 2010 at 5:53

    Using macbook pro, 50%-100% CPU usage makes the fans go nuts
