10.3.3 has screwed something up badly. I think the only thing for it is a clean install. But, how do I preserve all my data in Mail, Address Book and iCal--will Apple's Backup do it, allowing me to restore after I do a clean install, or should I take additional steps? Like copy my entire drive over to firewire--what files would I be looking for to copy back and where would they go on the newly installed drive? Any help appreciated, thanks!
