I'm not sure if I've updated yet or not. I was downloading 10.5.3 in Software Update, but I think somebody logged me out before it installed. I can't check as the Mac is carefully packed in a box at the moment, but I will later.
My iMac was doing the update, but I didnt feel like waiting for it to finish. So I got my MacBook and went to the other room. I never went back to go see anything new or stuff like that...I should probably update my MacBook too...
