That being said, with a little abstract thought, reasoning, and google, anyone should be able to diagnose whatвЂ™s wrong. There is a bit of nuance with it in that the guide wonвЂ™t tell you what to do should something fail a specific test, at least not obviously.

I suggest anyone having this issue download a copy and keep it on file both on your mobile device and on your computer.

Finally, I got ahold of the Apple Diagnostic PDF which the techs at Apple use to figure out problems. One site said to change PRAM batter, another said to switch the RAM around in their sockets. I then hit google again in an effort to better define my search terms and see if I had missed something. I was a little disappointed as everything I had read to that point had shown me that this would fix it. I ordered a new PSU, which came in a couple of days and installed it. I then deduced that it must be the power supply, as the random shut downs seemed to indicate that it needed to be replaced. After an entire afternoon of reading through what other folks did to fix this happening to them, I set out to try it and each test/fix failed. Hint: Nothing is ever as easy as you think, IвЂ™ve found. The frequency of which was impossible to predict, so I began the google search to see if I could dig up an easy fix. Ok, so I had noticed that my computer had been randomly shutting itself off. Single tray 6 Core, 32 GB RAM, RX580 GPU running 10.13 High Sierra.

IвЂ™ll walk you through what I did in the hope that someone else finds this useful.ДЇor background, I am on a 2009 Mac Pro 4,1 flashed to 5,1.

I had this issue very recently and figured out how to fix this after lots and lots of reading, trial, error, and re-reading. I am going to get another power supply to be sure, but what else could it be? Is there some other board I don't know about? Can someone help me interpret the LEDs? The customer already replaced the power supply, so I am wondering if the logic board is bad. I tried the SMC button, but that didn't do anything either. This also happens if I have the red lights switched on as I mentioned above. When I press the Diag button near the LEDs, the 4th LED lights up amber, but nothing else notable happens. They will stay on permanently after that. I can get the lights to stay on if I depress the power button while plugging the machine in and hold the button in for about 7-10 seconds. Those lights go out almost immediately and do not illuminate again when pressing the power button.

What I see are the top two LEDs that blink red momentarily in the upper left corner, below the #1 HDD. The only time something noticeable happens is when you are looking at the logic board while plugging in the power cord. When I press the power button, nothing happens at all, except a light odor of the magic smoke (from electronics, that is). I have a customer's Mac Pro, mid 2012 machine which won't boot at all.
