huynhj Posted March 7, 2007 Share Posted March 7, 2007 Hi, OS X system details show that my AMD X2 4400 is only using one core. Is there a way to activate my 2nd core? There's a post that said to delete the IOPCCardFamily.kext but I don't know how to find that file and remove it. Help.

aldrlandon93 Posted March 7, 2007 Share Posted March 7, 2007 Have you tried entering the "cpus= 2" during boot? Link to comment https://www.insanelymac.com/forum/topic/44442-only-one-core-working/#findComment-318120 Share on other sites More sharing options...
