Help! My Mac has been beach balling on almost every context switch, and I can't see any good reason for it, since it's got plenty of free resources: - CPU usage under 5% - 4gb free memory - 175 gb free disk space I've been running activity monitor to try to track down the problem, but I'm not seeing CPU spikes or even I/O spikes associated with the freezes. The problem seems to be worst for about half an hour immediately after boot (even after all startup programs seem to have loaded) or wake from sleep/hibernation. Early 2010 MBP running Snow Leopard. Any suggestions?
