Back again! This is a follow-up from my Cintiq/Kernal Panic
topic, but I put it in a separate post, because this how-to question might be of interest to others.
After spending inordinate amounts of time trying to track down potential villains, it appears that just connecting my Wacom screen via USB may be what's crashing my system. Applying the 10.6.8 Supplemental Update didn't help, so I've decided that reverting to 10.6.7 or upgrading to Lion are my best options. Both are problematic as the situation now stands:
I can't even start up in safe mode any more, so I will not be able to download either updater to my desktop. The screen freezes before I can choose a different boot disk from an option key start up.
Can I apply an update located on my laptop to my main computer if I've mounted the main computer as a target disk via firewire?
If so, can I simply install the 10.6.7 updater over 10.6.8 or would upgrading to Lion be my only choice, without having to wipe the destination hard drive first? Normally, I wouldn't move up to Lion till it's gone through another iteration or two. If I do wipe the destination drive, would the 10.6.7 updater install a complete operating system?
Is there a (simple) way just to substitute my laptop screen for the problematic monitor, till I get the desktop's OS sorted out? The same questions about reverting would still apply, I suppose.
Otherwise, it seems like I'll just have to start from scratch with my original Snow Leopard Install disk (assuming I can still start up from the optical drive!) and then update to 10.6.7. Will I have to do a clean install when going from the newer OS version back down to the original one? I know that's probably preferable, but it would be nice to be able to migrate my apps and/or settings if possible once I get back to 10.6.7, instead of having to move what I can from a clone and reinstall the rest.
I found two identically dated updaters at Apple:
Mac OS X v10.6.7 Update
Mac OS X v10.6.7 Update Combo
I assume I should use the Combo?
Thanks for listening!
