10.5.8 install issues on an external drive
So I turned the computer off, did a fresh clean install (without saving network or user info) and rebooted. Again, no probs with 10.5. I installed all the updates (Quicktime, etc.) first and rebooted....no problem. In downloaded only that monster 10.5.8 update again and let it run through the install. Rebooted and went to bed. I came downstairs this morning to an alarmingly hot imac sitting on the white screen with an apple and spinning white circle. It stayed that way all night while I let the update install, and my imac was alarmingly hot to the touch when I checked it this morning.
For whatever reason, it doesn't seem to like being installed on this external hard drive.
Has anyone had success in installing 10.5.8 to an external drive? I'm trying to determine if it just doesn't like this drive or if this is an issue with the update. I'm leery of installing the 10.5.8 on the computers internal hard drive if I don't have a bootable drive I can use for diagnostics if needed.
Mac OS X (10.5.7)
