Ever Since I updated to Snow Leopard, I haven't been able to run software update nor install anything via the Installer app. The installer never gets past the "Accept/Decline" window. Once I click "Accept, it'll just bump me back to the initial installation window. I tried updating the OS with 10.6.1, downloaded from the Apple site, and the Installer won't run!! Disk Repairs, nor maintenance scripts, neither zapping the RAM did anything Someone please help!!
