Activity Monitor showing ~3,000% percent CPU under normal use Shows huge percentages for dropbox but total is normal, and everything seems to be running fine. I have a Macbook with Intel Core2Duo
On OS X, 3,000% CPU would mean thirty processors are being fully used. I'm fairly certain that no Mac has ever shipped with thirty cores (even with hyperthreading), so this is not correct, particularly on a Core 2 Duo MacBook.
