Problems in Leopard-Upgrade Paradise?
Sunday, October 28th, 2007Stop the presses! Something appears to be wrong with Apple’s Leopard OS X 10.5 upgrade-installation process — at least on some Macs. I ran into the problem on one Mac. It manifests itself as a never-ending “blue screen” (not a Windows term, mind you) after Leopard completes “successful” installation, on the first restart. Many others have encountered the same issue, and you can see evidence of that in the Apple Discussions area in the thread titled Installation appears stuck on a plain blue screen.
If you read through the thread (as well as many others on other forums), you’ll find that various things are blamed for the problem, including an add-on customization utility called Application Enhancement (APE) by Unsanity.
The Apple Discussion thread offers a solution that involves booting in single-user mode, which requires you to hold down the S key while your Mac boots. Apparently that works for some people, but on my MacBook Pro 15, the only boot option that worked at all was Target Disk Mode (which lets you plug in a firewire cable and address the drive from another Mac as if it were an external drive).
