Nope...problem not gone.
Reference my previous posts here and here about this issue I’ve faced upgrading my old G4 AGP to Tiger and getting the weird, unpredictable, hanging gray-Apple-screen-of-frozen-death, which I’ve traced to SystemStarter in the console.
I’ve narrowed the culprit files down to something in the /System/Library/Cache/, as today I decided to delete recommended items stepwise in Safe Boot until I could boot normally again.
First, I tried deleting a few things in /Library/Cache that I thought might be the culprit, going simply by the date of modification/crreation (i.e., today). No help. So then I tried getting rid of Extensions.kextcache alone, but I still faced the screen-of-death.
So finally, I just deleted the entire contents of /System/Library/Cache, and this seems to be the cause (or something in here).
As far as what’s causing this: I’m not sure. I had a crash shortly before this happened and I ran Applejack. Reboot was fine, but a subsequent test restart was not.
BTW, here’s a great site for troubleshooting startup: http://www.thexlab.com/faqs/startupitems.html
To be continued I’m sure...?
