Hi there. I'm about to do an erase and install on my ibook, everything backed up .etc just a few questions: When I got my iBook it was installed with Panther. I have since upgraded to Tiger. I presume that I need to reinstall with the original discs I got, not with my tiger upgrade cd and that I will need to re-upgrade to Tiger once I'm done? Would it be wise to get the latest combo update for Tiger ready to install once I'm done? Cheers!
