I'd like to give BOINC my whole processor when I'm not using it but it never goes much above 50% of my iMac quad-core i5 running OSX 10.6.8. My BOINC Manager is 7.0.25.

I recently re-built my system after hard drive problems. Prior to the rebuild, BOINC would use ~100% of my machine.

What settings should I check to give BOINC more of my CPU cycles?
