SOLVED: Shutdowns all of the time!

It’s been nearly 6 months of the shut downs! I have a 15” Retina Late 2013 MBP.

I’m out of warranty but called Apple and was told to take it to the nearest Apple store or Best Buy Geek Squad. I took it to GS and they shipped it to Apple where they reapplied thermal paste.

It worked for a few hours letting me do everything I couldn’t for months. Then it started shutting down again! And the volume was out on one side. I sent it back, they fixed the volume but said they ran diagnostics again and found nothing. (I did notice that GS didn’t explain that the thermal paste did fix my problem for a night, they just wrote something like “redo, also volume is out now”)

I also want to note that after they worked on it the first time, during the time that it let me do a ton of things, it did shut down twice (long periods apart) but although the screen was black and all lights were off, the fan was really, really loud. I had to force a shut down both of those times.

The second time I got my laptop back, they had done a factory reset which didn’t help.

I called Apple yesterday to complain and they suggested I update my software (I hadn’t done so because I was afraid it might shut down during and make things worse).

I did the update (no shut downs) and then proceeded to use my laptop for a good hour doing things it would never allow me to do in recent months. I thought maybe the update had fixed my problem but I put it to sleep, got back on about an hour later and the second I opened Mozilla it shut down. Turned it back on, opened Mozilla, it shut down. Turned it back on, opened Safari and it worked for a bit but shut down a couple times there too.

This is SO frustrating. I use my Mac for work and have lost a great deal of money while going through all of this.

Here are things I’ve noticed:

  • When unplugged it seems to shut down more frequently, I once tried to flatten and save a large file in photoshop but it took me four tries where I eventually had to go about it a different way to get it to save,
  • I can use an external disc drive for hours watching TV with no shut downs (or only sometimes when it’s paused),
  • I can plug in an external hard drive and transfer files or view files with no shut downs,
  • I can play hours of Minecraft with no shut downs (though as time went on I did have a couple of shut downs while playing),
  • For the most part the shut downs happen while browsing the web (I use Mozilla), I’ve used an HDMI cable to watch a movie on my TV with no shut downs.
  • I can’t believe this has been an issue for some people for years and it is STILL an issue.

I wanted to list things I am able or unable to do in hopes that this will draw a better picture for someone that understands the inside of a computer better than I do. It’s interesting that the thermal paste seemed to work and I think the answer lies closely to that.

Is it possible that if I buy my own thermal paste and have that applied that it will work? I mean Apple just did that so I’m just not sure.

Update (11/16/2017)

This was directly after a shut down and restart. I did notice at one point while using it, It said 70°C, but that’s the highest it went that I saw.

Lets do some deeper diagnostics here. I suspect your system is overheating. But what is the root issue? I don't think Apple or the Geek Squad found it.

Give this App a try: TG Pro. Paste a screenshot of the main screen of TG Pro after you've encountered a shutdown (after you restarted) Time is important here so be quick! ;-}


Oh I forgot to mention this. I had an app I believe was called SMC Fan Control which I no longer have after the factory reset. I would use my MBP and check on the app frequently. It was tweaked a bit and they said to “bump it up” if I needed to but if I noticed the temp was real hot to shut it down.

I did notice two times the temperature went up to 106 and 109 and both times I shut it down immediately and it cooled off pretty fast. I set it to auto and stopped using it when I read that it should be used with caution because I didn’t want to make my problems worse.

Those two times that I shut it down because it was so hot, you could feel the heat near where the air comes out by the top speaker and it’s never like that when it shuts down on its own.

I can try the app you mentioned but am not currently where I can get WiFi so it will be a while. Thanks for the suggestion! Will keep you posted.


Lets pull SMC Fan Control! It could be your issue here.

Sometimes we think we know better than what the system knows is what it needs. People either set this to low or to high and it just doesn't respond as quickly as it needs to.


Yeah like I said, I no longer have it since the factory reset and hadn’t been using it for a while anyways because I wanted to get to the root of the problem and I shouldn’t have to use that!

Also I should note that I was having the problem for months before I got the SMC Fan Control, I had initially thought it was a fan problem which is why I got the app but I don’t think it’s the fans!


I added an update with a photo of the app you suggested, in case you didn’t see it. :)

I have been meaning to get on here for months to say that I finally found my solution! While searching around on this topic, I found someone else with the same problem only theirs had been solved. This actually worked for me after almost TWO YEARS of dealing with shut downs. Amazing!! I don’t fully understand why it worked, but it did lol.

I found it posted here: MacBook Pro Shuts down randomly

answered by @meilmut

Thanks, Nick :)

UPDATE: For those running Catalina, the process is a bit different and you can find the solution here: and there’s more information here, if needed.

I began having the problems after updating to Catalina and had to disable the thunderbolt ports through this process and am not having any more problems. :)

@kimberlyrenee - Sorry for the delay I got busy. Here's a snap from my MacBook Pro 2012:

I have a non-retina model. As you can see my high-water lines are quite high and mostly even. In your case your first core is running much higher (the full version will give you the true temps). In its self this is not an issue as one core often works harder. While I can't tell the temp different between the heat pipe outgoing air and the CPU should be about 25c.

I'm suspect the heatsink is failing here. The transfer tube is filled with a liquid what can happen is the tube leaks so it looses its efficacy. The only way to tell if the heatsink is bad is if you can see any evidence of a leak, a pin hole, white powder or staining on the logic board are the more obvious ones. Sometimes you just can't tell. Then we need to use a known good unit and weigh the difference with a good scale, the lighter one is the bad one,

Thank you for the suggestion! I will mention it to Apple when I call them back. I really don’t think it’s fair to have to pay for something I didn’t do especially when I already spent nearly $3,000 on this thing. I’m going to try my hardest to get it fixed through Apple before I do anything like that myself! Thanks again :)

I own a late 2013 rMBP 15”, I had the same issue of frequent shutdowns and no patterns as to why shutdowns happened. But, I did notice something unusual, when my Mac was plugged into my TV via HDMI port it never ever crashed.

“For the most part the shut downs happen while browsing the web (I use Mozilla), I’ve used an HDMI cable to watch a movie on my TV with no shut downs.”

The solution that worked for me was buying a Dummy HDMI Plug (4K) for 8$ on Amazon. I popped it into my HDMI port and it worked like a charm!

I think the issue is with the OS trying to shutoff CPU cores and restarting them. The dummy HDMI plug tricks the OS into thinking that all 4 cores need to be alive for a high resolution(4k) display. Doing this will impact your battery charge life by 10-15% on a full charge, but still immensely better than constant restarts.

I hope this really helps.

PS: I still have an occasional issue with fans going crazy after putting my mac to sleep.

@ragingbull - Yes! After fighting a few of these it became clear the logic board video switching logic has issues! Adding a load as you did on the HDMI port does appear to solve the problem.

As to what caused this I'm suspecting a ground loop was created between the system and the display/TV.

Many monitors & TV's have polarized power plugs so the neutral side is tied to ground.

What can happen is someone mis-wired the outlet so the normally neutral side is tied to the hot black lead or someone forced the plug into the outlet incorrectly (I've even seen people file the edge off the plug) or they are using a cheater plug on the 3 prong plug backwards, very old buildings don't even have polarized outlets!

Bottomline here, is the neutral side becomes hot! Just enough not to pop the breaker. Over time this leakage damages the logic board in your system.

How to reset NVRAM on your Mac

If you experience issues related to settings stored in NVRAM, resetting NVRAM might help.

How to reset NVRAM

Shut down your Mac, then turn it on and immediately hold down these four keys together: Option, Command, P, and R. Keep holding the keys for about 20 seconds, during which your Mac might appear to restart. (If you have a Mac that plays a startup sound when you turn it on, you can release the keys after the second startup sound.)


When your Mac finishes starting up, you might want to open System Preferences and adjust any settings that were reset, such as sound volume, display resolution, startup disk selection, or time zone.


Yes I’ve done both of those things and like I said, the second time I sent it to Apple they did a factory reset. I just updated to High Sierra a couple of nights ago. I will try tonight to do those things again since I haven’t tried after the factory reset. Thank you! Will keep you posted :)


Still haven’t got a complete fix, as you can see by my other posts, I’m still having problems. But I did downgrade to OSX Mavericks and the shut downs (or hibernations, whatever it is) have stopped! But I’m having a big issue with a black screen, and loud fans. I have to shut down by holding the power button. It comes back on and works for a while and then the same thing happens. Sometimes it’s more frequent sometimes it goes a very long time without. It’s very irritating. But downgrading did help. I wondered if it’s because I went from Mavericks all the way to Sierra with no big OS updates in between (Lion, El Capitan, etc.). Maybe it would’ve worked fine if I’d updated each time? I don’t know. But I’ve got this new problem to fix now. Thanks for the help!

May I - I’m not sure how this works i usually am pretty lucky with other posts people solved issues i had and i followed along and solved them all. Macs break all the time huh.

I’m having the same problem, since last night the MacBook Pro 2013 (mid 2012) which had a motherboard replaced twice since i bought it - also replaced batteries 2x - now started restarting chimes goes into Apple logo charge up and then it will do it again and again.

I was able to get it running a few times. I did open and disconnected battery and left it for some 10 mins and put it back together and it worked. Until i looked at everything to see what’s up. I’m trying to update and when i restart it starts again the same issue.

That’s when i started reading this. I’m going try what you suggested too. Any other tips?

I have two 15-inch MacBook Pros 2013 experiencing similar problems. One will start up with chime and fans with a completely black display no back light comes on. The other will turn on with a back light on without an image no chime and fans going full speed.

all the usuals tried it with and without the charger, reset SMC, reset NVRAM. Still One with backlight and no image the other with no backlight or image.

In determining if it’s the display or graphics card I plugged into the thunderbolt port nearest the Magsafe power port a Display port to HDMI adapter with an HDMI cable running to a TV.

Recalling the F1 key was once used to throw a signal to an external monitor, I began tapping back to you as I turned on the Mac. Just the power cord and that mini display to HDMI adapter.

In both cases the Macs turned on normally. I don’t recall seeing the image on the external monitor, but I was pleased with the fact that I finally had an image on each computer.

Now on to troubleshooting the cause. At least I know how to get the computers running again. In both cases, my clients reported instances overheating (I’m an independent apple repair shop owner). My hunch is that the machines really overheated on account of being unable to find the operating system. This time my theory proved correct, because when the computer came on I had the flashing folder with question mark

I’ve always associated fans on high speed as an indication that it’s unable to find the operating system. Reasons for a missing OS often points to either a bad or disconnected drive.

Sure enough in one of the computers the one that was getting blacklight but no image any the customer had recently upgraded the hard drive himself. I suspect there’s an issue with the drive he used or in the process of re-connecting it. The other Mac that had a chime and completely dead display (no light or image) has no hard drive in it at all.

So I’ve given you a lot of information here. The main take away is that two 15 inch MacBook Pro 2013 models with no display got the image back on by plugging in a mini display port to HDMI adapter and powering up tapping the F1 key.

Feel free to share any thoughts you may have on the situation. Let me know if you try this and if it successful for you.

yes please overlook the minor typos and incorrect words. We can attribute that to Siri taking the day off.

Thanks and good luck.

I made a video for this which hopefully makes it a little easier if anything doesnt make sense, or type (Does you Macbook Pro A1938 (2013-2015) Keep Shutting Down Watch This)

into youtube

For OS Mojave:

Shutdown Mac (Hold) Command+R (Turn On)

This enters recover mode click on Terminal in the top left under Utilities


csrutil disable (enter)

Restart Mac Go to finder and find this:


Change the name to


Shutdown Mac (Hold) Command+R (Turn On) This enters recovery mode again click on Terminal


csrutil enable (enter)

Restart Mac Hope it brings you as much happiness as it has me :-) This is with Mojave if you have Catalina as far as I know everything is similar except in finder it looks like this


change to
