Brief summary of the problems I'm encountering. My system has been running fine with no issues at all. Recently I installed an update to OSX and a couple of other applications. Since then my system will hang on shutdown, restart. I have Firefox, Safari and other applications now hanging as well since these updates were installed.

Is anyone else having these problems?

Machine Specs:

Mac Pro
Quad-Core Intel Xeon
Processor Speed: 2.8GHz
Number of processors: 2
Number of Cores: 8
Memory: 8GB
Bus speed: 1.6GHz

Software:
System Version: Mac OS X 10.5.5
Kernel Version: Darwin 9.5.0

I have jumped over from my windows workstation to Mac about 6-8 months ago and I should have made the jump many years ago but did not. I've been working with FreeBSD and Linux for 15 years now so the jump over to Mac OS X has been seemless.

Does anyone have any advice on this problem? I do NOT feel like reinstalling/configuring this box because I feel that the problem has been with the updates. Any help out there?

TIA,

T
