Just about ready to launch this machine out the window it's driving me crazy.

Ok so a rundown of what has happened thus far.

Bought a Mac Pro Tower around 2010, worked like a dream for 3 years then due to circumstances it had to be put into storage for the past 2 years.

Anyway when I got it out of storage a few weeks ago and fired it up I noticed that it keep randomly hanging and nothing would allow me to resume control. Due to the age of the machine I figured it could have been a failing HD, so replaced it with a new one and done a clean install of Snow Leopard.

That didn't make any difference, so after asking around on here I got told it could have been the PRAM battery, so I then replaced that too and again it made no difference.

At that point I took it into the Apple Store, it crashed twice when they loaded their own OS on it so they kept it in for further investigation. They then called me up to say that they couldn't find any hardware faults but that they did install a newer version of Snow Leopard.

So I have just got it home, set it up and it crashed yet again.

Any ideas what I should do now?

  • Take it back to the Apple Store and tell them it's still crashing? Have you seen apple.stackexchange.com/q/34110/24154? Have you spent some quality time searching past questions on this site? – D.W. Apr 9 '15 at 21:22
  • Did you reseat the RAM? – IconDaemon Apr 9 '15 at 22:58
  • I have been trawling through the web looking for way to troubleshoot the issue but haven't had much luck so far. I have reset the ram a few times, as per one of the answer in my previous question – cosmicsafari Apr 15 '15 at 13:49
  • I had hoped to get the link to that question but can't seem to find it. In any case I would be happy to try resetting the RAM again if you could provide the best way to do it? – cosmicsafari Apr 15 '15 at 13:58

Yes - troubleshooting this could be easy if you take some time. Get a notepad and write down the times of the problems - day, minute, second. Over time a pattern will emerge.

Save the logs - after it crashes - run the command sudo sysdiagnose as this will package each crash and the logs for later analysis.

Pay attention to what crashes - is it a kernel panic, a freeze, an abrupt reboot. The steps to diagnose each is slightly different. We have a [chat] for getting troubleshooting help if you need a start.

  • This behavior has meant a failing (or failed) motherboard in the past. – Zo219 Apr 10 '15 at 1:52
  • @Zo219 That would certainly cause the symptoms. I'd also start triaging RAM since it's so easy to change on Mac Pro. Without more software logs, it's hard to know what a "freeze" is and whether the new HDD is really flawless. I've seen a new part be faulty and really drive the troubleshooting process to bits since it's assumed to be good since it's new. – bmike Apr 10 '15 at 1:58
  • Open Console to see all the logs, and control-click to Show in Finder. – Zo219 Apr 10 '15 at 2:15
  • Sorry it took so long to reply, not having a working machine has been a pain. When it hangs I literally can't do anything, even the mouse cursor freezes in position. It appears to happen alot when I connect to my wifi network which made me think it was the airport card causing the issue. – cosmicsafari Apr 15 '15 at 13:47
