I just got Logic Studio and it's big program with lots of parts to it and before I install it I wanted to make sure things are cool with my iMac. It's been crashing a fair amount recently. I called Apple and the girl (really nice) in the general section said it's probably good to take the imac to an apple store or apple authorized tecnhnician (and she gave me several in the area) and have them give it a once over. Then I spoke with a guy in the pro apps department (nasty and bored) who said the thing to do is: 1) Try running disk utility from a system bootup disk (Leopard, wchih I have around here somewhere) 2) Do an Archive and Install from the Leopard Disk (and then get all the updates etc). which will just replace the system, not anything else. 3) Do an erase and install from the Leopard disk, which will mean having to reinstall any third party apps. Whadaya think?
