My problem has changed now, so I am starting a new thread... [800MHz 17inch iMac w/ 512 MB RAM] I did an archive and install from my 10.2 CDs and it corrected my old problems [previous thread of Mac dying]. Now I have a new problem. I tried to use Software Update from the System Preferences to update from 10.2 to 10.2.8 again (which I had), but the installer FAILS. It prompts me to download the update to the desktop and install from there. I tried and the installer won't work. I have choose to open the file, and then it comes up with a blank shell. The same is true when I try to reinstall my printer drivers from the CD. I repaired the permissions (again), but that didn't help either. Any suggestions? I've been working on this all day, and I'm so close to being back to normal! I just need to get this installer problem licked. Thanks!
