I just received a new Mac Pro about 4 hours ago and after adding in my modifications (1Tb drive array, extra 4Gb ram, 2nd DVD burner) I fired it up. The thing is very fast, but quite unstable. In the last 4 hours I have had no less than 4 kernel panics and aperture crashed 3 other times. I have pulled out the extra 4Gb of ram from OWC and it seems to be running stable (45 min now), but I wondered if anyone else had any ideas on what to troubleshoot next. Could the software raid 0 array be an issue? I also have a logitech MX500 mouse that I love, but the drivers are not playing nicely with this new mac. I like to use the logitech driver to map all the extra buttons to expose and other various key shortcuts on my Powerbook. Is there another piece of software that can do this for free? I know of USB overdrive, but I'd like to play the field a bit before dropping another $20. Thanks!
