That's right, my MacBook hates 10.5.8. Ever since updating: The fans keep going on and off because the CPU or Airport Card are hot (but I'm not doing anything that would require heavy processor or Airport use) My MacBook has frozen twice and required a hard restart The Mail App dock icon looked like the attached photo for a while. The icon became a weird jumble of whatever was on the screen at the time. It went away when I quit and restarted Mail. Safari keeps freezing up The spinning beach ball keeps asking for attention There was a random white square next to the Spotlight icon in the Menu bar (it disappeared when I clicked on Spotlight- I should have taken a screenshot first) WTH? Anyone else experiencing any of this? Any solutions if this doesn't self-resolve?
