Hi, I've had the same problem with mine. The crew at the applestore, after several tests said that it could be the motherboard. I searched the internet and found the solution in this link. I did this in June 2018, and my MBPro works flawless since. MacBook Pro 15' Retina Display Late 2013. Hold down the Power button on the Mac until it shuts down completely, this may take 5-10 seconds or so. Wait a few seconds then press the Power button again to boot the Mac. 2 Check for Updates Select the Apple menu, then App Store.
If your Mac still won't shut down, the only thing left to do is to figuratively 'pull the plug' and force a shutdown. This works on both desktop Macs and MacBooks. To do this, first press and hold the Control and Command keys, then hold the Mac's power button. The question why do MacBook Pro/Air, iMac, and Mac mini permanently crash pops up on the Apple support community pretty often. Very few Mac users manage to keep calm when a ‘spinning beach ball of death' appears on their Mac's screen. Even worse, macOS Sierra/High Sierra can get stuck on the ‘grey screen of death' after routine updates. Apple's got a fix for the 'random shutdown' issue on some 13-inch MacBook Pro machines.
This week, an updated Apple support article offers a reminder on what to do if Mac OS X Mail keeps crashing ('unexpectedly quitting' in Apple-speak). The most likely cause is a 'damaged' or otherwise problematic message. In such a case, Mail will initially crash as soon as you select the message and attempt to display it.
Unfortunately, this is only the beginning of your trouble. It gets worse. When you relaunch Mail, it will return to where you left off, again attempting to display the damaged email. Oops. The message will thus cause Mail to crash again, before you get a chance to do anything else. Can you say 'endless loop'?
There is a way out of this. The first step is to hold down the Shift key when launching Mail. This forces Mail to open without displaying the crash-inducing message—or any message at all.
Next, drag the horizontal divider in Mail's window window so that you can no longer see the area for the display of messages. You can now make a selection in the left-hand column. Only the listing of message titles should display.
Finally, single-click on the message that was active when the crash occurred. Select to delete it. Assuming that the deleted email was the only one causing the crash, your problem should now be over.
After a number of MacBook Pro users complained about their computers randomly shutting down, Apple officially acknowledged the issue and offered an unusual way to fix it.

Apple Computer Keeps Shutting Down
The problem is with the 2019 13-inch MacBook Pro computer with two Thunderbolt 3 ports (although I wouldn't bet it's limited to that model; more on that later), which 'randomly turns off even though the battery shows a remaining charge.'
Why My Macbook Keeps Shutting Down
For more on the symptoms, check out this thread on MacRumors. I can describe it from personal experience, because it's happening to me, too: With my MacBook Pro's battery discharging, during normal use (so, nothing CPU-intensive like gaming or rendering a video) it just shuts down when it gets to about 20-30% battery.
The difference is that, in my case, it's a 2017 13-inch MacBook Pro with four Thunderbolt 3 ports, and it's a rare occurrence, whereas it seems to be happening quite often for some users of the newer machines. Obviously, my MacBook Pro could be suffering from a different issue altogether, but it is quite similar to what other users are describing.
SEE ALSO: Holy crap, the maxed out 16-inch MacBook Pro costs $6,099 War thunder register.
In any case, Apple's advice on how to fix it is as follows: Get your MacBook Pro's battery to less than 90 percent, connect it to the power adapter, quit all apps, close the lid (which should put the laptop in sleep mode), and let it charge for at least 8 hours. Then, update to the latest version of macOS.
If the problem persists, Apple says, contact Apple support.
