GPATPANDP Just a follow up to my post the other day...I did everything possible in running every disc utility I own/possess (ie Tech Tool Pro, Disc Warrior, Cocktail) and I even acquired Apples own Service Diagnostic DVD and completely ran every test. Despite this fact, every test I performed passed and cleared any possible relationship to my machines hardware or existing software as I continued to experience frequent system stalls (blue screen lock up) while either restarting or shutting down after updating to OSX 10.5.3. Upon erasing my hard drive and transferring over from my firewire back the exact same system though still of the previous 10.5.2 OSX version, I am back up and running flawlessly. I resent the very brief and ineffective conversation I had upon indentifying this issue with an Apple Care technical support representative the other day. I tried in ernest to express that this problem was unique in my updating to the latest OSX 10.5.3 release, though she was dead set on wanting to attribute it to something on my end thereby justifying the $50 fee. Well at the very least this proves I knew what I was talking about and I am glad that I did not succumb to needlessly pouring my own money down the drain
