MacBook Pro randomly shuts down.

I am the proud owner of a MacBook Pro 2014 15", but i recently started getting an issue where it shuts down randomly.

This problem started about 1 and a half week ago on macOS 11.7.4

When I "ask" the terminal is gives me "recent shutdown cause error code -128".

This happens when I'm using battery as well as when using AC power.


I've tried a number of things:

  1. Resetting the SMC as wel as the PRAM. (Ctrl + Option + Shift + Power / Option + Command + P + R)
  2. Reinstalling macOS. (2 times 11.6.8 and 2 times 11.7.4)
  3. Using the Mac in "Safe Boot". (Shift on boot)
  4. Replaced the battery. (was over 1425 cycles anyway)
  5. Hardware test, nothing showed up. (Command + D on boot)
  6. I tried to delete appleThunderboltNHI.kext. (was back every time/not sure it worked)
  7. Installed Ubuntu 20.04 LTS. (no problems)


Meanwhile i installed macOS 11.6.8 on 2 MacBooks using a usb.

The problem is only on one device so it also isn't the installer-usb.

I now have installed Mavericks (original to this device) to see if that works. (to be continued...)


It also doesn't happen when it's on screensaver. (I left it for 2 nights and it stayed on)


Apple support tells me it's a hardware issue but I found it weird that Ubuntu works then.


I'm hoping one of you guys may be able to help me to at least tell me what the issue is.

Update: did not replace SSD but did disassemble and clean for first time in a while. I wasn’t hearing the fans spin up that much but did notice the laptop would get kinda hot. Sometimes they would turn on but not usually. I sprayed out a bunch of dust that was all over and also inside the fan assemblies. It was kind of a lot. I think the process of disconnecting the battery, spraying out all the dust from the fans, and also replacing the thermal paste (which I did because I was already in there so I figured why not), has seemingly resolved the issue. Computer gets much less hot and hasn’t shut off like it was doing. I also noticed where the SSD would go if I were to replace it and it would be super easy. Easier than taking apart the fans or replacing the thermal paste. I didn’t have an appropriate SSD lying around so I didn’t switch that.


I think the computer was getting hot and trying to start the fans but was getting resistance due to dust and so the fans sent back a signal saying “hey we can’t do our job so turn off before you damage us.”

This is happening to me as well and I’m furious! I get it out laptops are old but mine is in great condition as well and was running perfectly till I downloaded big sur 11.7.4. This is no coincidence at all. I also don’t have the money to shell out for a new MacBook Pro right now. I would like to resolve this issue as well. Nothing is working.

Big Sur 11.7 here on a mid 2014 15” MBP.


11.10 is available… at this age updating usually means downward performance though right?


Computer battery has been dwindling and it’s about time to replace the machine. I was hoping to get the 2023 M2 Max but now the M3s are out and at the store it seemed like the hinges on these newest ones aren’t as good as the ones from earlier this year. That could be just the couple I tried or some other thing. Anyways, till soon when I upgrade I need this machine to keep chugging. But lately it’s been shutting down either when I shut it to sleep it or just randomly while watching YouTube with maybe Notes and Messages open in the background.

I'm having the same issue with the same MacBook, 15". Radeon 560x 4gb Graphics, 32 GB 2400 MHZ with updated Sonoma 14.2.1 IOS. It shuts down for about 30 minutes and then reboots itself, almost like it's reloading a new OS but that's not the case. Another person on this chain mentioned heat being a possible culprit. I did notice that the Mac was pretty hot just after it shut down. This has happened three times since mid-December, 2023.

So I have a Macbook Pro 2023, that for 1 year, just randomly shuts down and restarts on its own. No error message, and according to the genius bar, has no record that this is happening, Like I'm lying or something! BS!!!! Why the heck would I waste my time coming in, calling and chatting about a problem that doesn't exist! I cant believe this. I am a loyal Apple using and have all Apple products, you name it I have it and now this BS. I am just wondering if anyone else is having a issues like this! I need help because I am a therapist working remote and it isn't good to have your session interrupted by your computer shutting down!!! So what does Apple plan to do??? Who knows ...maybe if some other people share if they are having the same issue then they will believe thatI am just just wasted my time with calling, going to the Apple store and chatting for a made up problem!!! Come on people...

Hi

I too have a 2014 mac book pro, and yes mine also shuts down, I wouldn’t say it’s random.

its usually a couple of minutes after switching on, screen goes blank, but the keypad stays lit for a while then all shuts off.

ive done everything that is recommended on the apple webiste. Wiped and reinstalled with IOS X, does seem to coincide with Big Sur

Im not a techie, so could some one explain what a SSD is, as someone mentioned replacing??

dont think its an over heating problem as it doesn’t have time to get hot!

any advise would be great.

I believe MacBooks don't like getting even slightly warm and tend to shut down as a result. What I find worked was to put it in a bag (to prevent condensation) and place it in the fridge for a half-hour. Works okay afterward, once it's gone through the startup palaver. I also put it on a large ice pack to keep it cool and I could keep working away on it. Anyway, this was my effective solution for about a month but it doesn't seem to be a problem now, which is ironic, seeing as how it's the start of summer! So, things are back to normal, though I still can't get sound out of the device's speakers, and I can't afford the big Apple dollars needed to fix it.
