I use a lot of plug ins for music production in Logic. Like an idiot, i upgraded to snow leopard, after having this problem with the upgrade to leopard from tiger. Of course half of my plug ins dont work. So i Time Machine backed up everything on my HD. I put my old leopard install disc in and restored to my Time Machine volume. It took about 2 and a half hours. At the end of that, it asks you to restart, and i do and as soon as the apple pops up on the off-white screen, kernel panic and i have to restart. this is never ending Ive tried repairing and verifying disk permissions from the leopard disc of my HD and still nothing. My final guess would be to just do a clean install of Leopard and then restore from time machine again. This seems SUPER risky to me as there are TONS of important project session files that i CANT afford to lose. Everything is backed up on my Time Machine drive, im still just a little nervous about doing this. Anyone have any other ideas and does this sound like a secure plan?
