[QUOTE="pigoo3, post: 1646781, member: 56379"] If you REALLY want to troubleshoot this…I wouldn't have anything running other than OS X related items. One thing you want to determine is…is the problem a software thing or a hardware thing. To absolutely eliminate it being a software thing…you could boot the computer from an external device with a fresh install of the Mac OS (and the Mac OS only). Then you see of you still have the 98% CPU issue. If the problem goes away when doing this…then there's a software issue on the computers internal storage. If the issue remains…then it could be hardware issue. I previously had a MacBook Pro that had a bad fan…and this caused extreme CPU use. So what I'm saying is. High CPU %'s can be software related and/or hardware related. - Nick [/QUOTE]
