MacBook Pro (2008, I think, 4 GB RAM), OS X Snow Leopard. Starting a few weeks ago, it began to stall for 20-30 seconds, again and again, every 3-4 mouse clicks. Does it in all applications. A few actions will go normally, then suddenly, I'll click and the Mac will do nothing for 20-30 seconds. Usually lasts very close to 20 seconds (which makes me think it is waiting for something which times out). Often there is a spinning beach ball. Cursor still moves and I can grab and move a window; sometimes I can click on another window to bring a different app to the front; but I can't actually do anything. Then after the 20-30 seconds, it resumes as if nothing is wrong, until it happens again, a few actiona later.
What I have tried:
- Getting rid of all extraneous apps, pref panels, e.g. LogMeIn, Hamachi, Logitech keyboard software, Kensington Mouseworks, Growl, etc.
- Disk Utility's FirstAid found no disk issues, several times
- unplugged everything and ran with just the naked MacBook Pro -- no USB or other devices
- Unplugged Ethternet and turned off Airport
- Replaced hard disk (which I was planning to do anyway)
- Wiped the hard disk and reinstalled OS from scratch, using migration assistant to bring back my data
- Disabled Spotlight by dragging hard disk icon into Privacy panel
- Ran TechTool. It found some virusy sounding files so I ran Sophos virus scan which found some turds, which I cleaned up
- Removed and reseated RAM
No changes.
Any ideas? I am running out of guesses!!
