Ok. I've had enough of the continual glugging out of my mac. every day I have to reboot because programs start throwing up the beachball and it won't go away. even system preferences and process viewer. I figure it's coz I have 10.2.8 and i've loaded so many little system add ons. I used to do the same thing in my windoze daze and have the same problem. But then I knew what to backup and how to restore it. I'm only 2 mths old on the mac. 1) How and what do I backup and then how do I restore it? (i.e. which directories and files) 2) I also use FinalCut Express. Will I have to re-link all my movies??? 3) Is it possible to wipe the system without wiping data? And then reinstall the system? thanks heaps Chris PS Or if someone could just tell me how to work out what's causing these glugups, I'd appreciate it.
