Well, I backed everything up and reinstalled Snow Leopard (should the crashes persist I will downgrade) after formatting my drive. A slight problem, however. On Time Machine, when I attempt to restore my old User files the dialog prompts "The alias [insert file] could not be found because the original file could not be found." I managed to retrieve my iTunes library but everything else is trashed!
To KingYaba, I previously had Safari 4, Opera 10, and Camino. I use Camino for most Java applications (as Safari doesn't have a maximize button and I'm not installing Glims or that other 3rd-party). Camino does not work with 10.6 without tweaking (which I added the new Java file) and Firefox is just as buggy. Which brings me to say that I do not install non-Apple 3rd parties.
I have backups of both 10.5, predating August 28th, and backups of 10.6 before formatting. The TM backup only reads the backups of May 2nd through April 22nd. I made sure I backed up before formatting. What is wrong here?
