So, I use iStat Menu's, Geek Tool, and Activity Monitor to monitor my system performance. A while back, I don't know how long, the CPU usage stopped displaying. (See attached pics). I don't know what to do to fix. I googled for about 30 min, and came up empty, so I figured that I would come to the experts here @ macrumors.
Any help would be appreciated. Thanks.
(Here are some SEO keywords for others that may come across this problem:
iStat not displaying cpu percentage
mac os x activity monitor not showing cpu usage
geek tool won't sort by cpu usage
Thanks)
