I've had this Mac Pro for about 3 or 4 months I suppose. And lately, Quicktime and iTunes have been crashing just randomly. Sometimes straight away on startup and it takes 4 crashes to actually stay open, other times it's fine straight away. I've done tested the Machines RAM with Memtest and Rember, pulled it out and put them in different slots and put the RAM back down to 2GB. Deleted all the preferences, new accounts, repair permissions, all the usual stuff. In the end I just got the ***** so reinstalled the whole OS onto a different hard drive. Fresh install, latest updates, and does it again with Quicktime and iTunes. It never really seems to affect any other programs. (I did get Adium crash today, but that's very very rare) Anyone else having issues with 10.5.7 ? Mac Pro, 8 Core, Dual 2.93GHz 12GB RAM ATI 4870 It's really bugging the crap out of me, and I've tried nearly everything I can think of.
