Hi everyone, I have a new SR Macbook, and I haven't updated any of the latest updates (I became unsure of whether I should update after reading about what the Quicktime update has done to some users). So basically I haven't updated: Quicktime (7.3.1) Macbook Software Update (1.1) Garageband (4.1.1) Security Update 2007-009 (1.1) Should I update one or all of them? Is the Quicktime update the only one causing the problems? Is it better to download updates from Software Update or on apple.com? Is it better to shut down after updates that require restarting, or should I just restart? Thanks!
