Hi all, Specs on my computer as follows: Model Name: Mac Pro Model Identifier: MacPro1,1 Processor Name: Dual-Core Intel Xeon Processor Speed: 2.66 GHz Number Of Processors: 2 Total Number Of Cores: 4 L2 Cache (per processor): 4 MB Memory: 8 GB Bus Speed: 1.33 GHz OSX - 10.6.8 Norton Security Suite for Mac For about a month now, I have become the beach ball lady. It doesn't matter what application I run, there are times when any application I choose will hang after a while....Final Cut or Calendar or Finder. it seems that the beach balls are more frequent if the computer goes to the screen saver or black screen mode. A reboot fixes the issue, but only for a while. Norton has shown no issues. Any ideas?
