Desperately Need Help - Cannot Update or Install Software
have an iMac Intel Core 2 Duo running on Mac OS X 10.6.4 I can't update existing software or install new software. Every time I try the installation either does not occur (e.g. for the Mac OS X software or iTunes where the install occurs with a re-start) or gets hung up a the last stage of the installation. I have a time capsule as well so am wondering if I should just reinitialize the whole system. I've already tried creating a new administrator and installing updates from there but that does not work either. PLEASE HELP
iMac, Mac OS X (10.6.4)
