installing without erasing will only overwrite the main system files. your personal settings (in /Users/<pathname> ) will not be altered. in fact, they might get backed up to a directory called "old-home:.
still, backing up is not a bad idea. you might find the system has inconsistent operation unless you erase and reinstall. part of this is from settings files in /System and /Library. by erasing, you set the system to "factory new". then you can import your /home from time machine and whatever apps you want to have. -Eric On Jan 24, 2011, at 1:48 PM, Sarah Alawami wrote: > Well it looks like my OS problem din't go away and I don't want to do it but > it looks like i need to reinstall.
