I remember months past when leopard was released that people were experiencing the default OS X blue screen with a mouse cursor, but nothing else. The problem persisted after rebooots but was eventually atributed to having installed Unsanity's Application Performance Enhancer program. John Gruber wrote a really thorough article (http://daringfireball.net/2007/10/blue_in_the_face) with solutions, and even laid out some bitch slapping to Logitech for allowing stuff like this to get installed in the first place.
But the truth is I never paid much attention to the BSOD Leopard upgrade issues because my upgrade went so smoothly. That is until someone brought me one of these dead MacBook's a few days ago. And then amazingly enough, another one today. In both cases it was due to installing the unfriendly APE.
Here is how I removed it.
Use Command-S on bootup (hold these keys before the grey screen shows) to enter single user mode (command line). You should be on a terminal shell now as root. Do these commands:
fsck -fy /
/sbin/mount -uw /
rm -rf /Library/PreferencePanes/Application\ Enhancer.prefpane
rm -rf /Library/Frameworks/ApplicationEnhancer.framework
rm -rf /System/Library/SystemConfiguration/ApplicationEnhancer.bundle
rm -rf /Library/Preferences/com.unsanity.ape.plist
exit
restart
Now in my case this didn't work, but plenty of others (http://discussions.apple.com/message.jspa?messageID=5646899#5646899) have reported it will clean APE off your system and set things straight. So what I had to do to fix my issue was to boot from my Leopard Install DVD and choose to reinstall with the Archive and Install option. 95% of the applications run as normal and all of the user data, documents, and other stuff was preserved.
Alright this is here for posterity now. If anyone has this issue I hope this helps them.
