Hardware 5,1. I have replaced the power supply once. Machine keeps either rebooting or display the "your mac has a problem and needs to reboot screen". This is on a largely mint OSX and audio app reinstall. Zero internet connection time on this machine.

Here follows the one of the crash reports. I believe the machine doesn't have a good serial number installed in the firmware due to previous work done. This is causing a lot of authentication errors in the internal messaging system but was not a rebooting problem previous. I recently upgraded to high sierra and the problems commenced 3 days later. The machine was running like a dream for those 3 days!!

  • I'd update the Accusys; or remove it altogether for testing. 3rd party kexts are always prime suspects. Also, test safe boot & using a fresh admin account; or fresh install on a spare drive. – Tetsujin Sep 29 '18 at 11:50
  • i recently removed half the RAM and saw much less of a problem with hangs but its still happening...What is the Accusys? Is it the usb3.0 adapter?? Problem exists with it installed and with it removed. – Charles Spencer Sep 29 '18 at 12:01
  • Does my crash report have any specific indication of what the problem is? – Charles Spencer Sep 29 '18 at 12:04
  • This is looking like it's CPU related; though I would thoroughly test the RAM first. Do this by removing ALL RAM (not just half) and only booting with a single stick. If you can get a hold of known good RAM, even better. – Allan Sep 29 '18 at 12:05
  • I will try although I thought RAM must be installed in pairs... I am considering a costly CPU upgrade but need to know the rest of the machine is OK before pulling the trigger. – Charles Spencer Sep 29 '18 at 12:09
