      What are your settings in the BOINC manager Activity menu?

      Do you use local preferences (Advanced menu)? If yes, they override the online ones.

        Hi!

        The CPU scheduling of Mac OS X Leopard seems to be quite buggy, especially making processes run as "nice" (low priority) has problems in OS X Leopard, see here for example. Restricting the number of cores that may be used simultaneously by BOINC for multicore CPUs seems to be a good way to limit BOINC usage of your CPU.
