MORPHER My MacBook on OS X.6.2 started behaving oddly. Some programs (Eudora, Personal Organizer, Mike's Cards Lite) started to be flakey. Boot and shutdown times were getting longer. Then I installed the updates for iTunes (which I almost never use, but I like to keep the versions up to date) and something else (forgotten what it was, but it was in Software Update), and I was in serious trouble. Eudora crashing, Personal Organizer wouldn't launch, EarthDesk wouldn't launch, Mike's Cards was taking seconds to move a card, after launching at a stagger. Booting up took forever, shutdown took minutes.
Many runs of Disk Utility made no difference.
I ran Maintenance 1.2.5 which told me that I had entered an incorrect password (I hadn't) but when I clicked on "Execute" it worked. I ran the default maintenance. Then I shut down for a few minutes, and rebooted.
Hallelujah, babe! I was up and running again with all systems GO~!!!
I've just upgraded to Maintenance 1.2.6.
(Version 1.2.6)
