My MacBook pro is a little over a year old (maybe by a month or two). I got my iPhone 4 today (yes, it's a day early) and I was trying to sync it. I haven't updated my MacBook in a while, and it said I needed to have 10.5.8 to sync my iPhone. So, I was trying to update Leopard through Software Update and it said "This update requires you to Restart....." and so I clicked "Restart". Well, it didn't do anything. Software Update disappeared but stayed in the dock, and my MacBook just sat there on the desktop not doing anything. Please let me know what I can do to update Leopard on here. Thanks!
