I noticed my CPU time was running between 50% and 100% according to my menubar monitor while I was just running Safari & Adium. Activity Monitor confused me more. It shows User percentage as 45% (the colored options at the bottom), while the list view showing all processes only has a highest value of 3%. (Often it was 90 and 3ish) While everything is fluctuating, the menubar monitor & User percentage would match. (Act. monitor refresh set to normal 2 seconds) My boot time was on 10 hours, and I had just run a complete Onyx run 3 days beforehand. (and no, spotlight wasn't indexing) No applications had been force quit either. I'm behind a software & hardware firewall. Whats going on here? It stopped after I logged out and back in...and this is the second time its happened.
