Random Shutdown on Macbook Pro (15" mid 2014)

Lots of us still need the Ethernet over Thunderbolt functionality 😠

The irony here is that Apple made MBP more stable when running Windows than macOS 😁

Is apple censoring this thread? I cant see this comment here, only in my mailbox i can see the preview

Say what? That's definitely not a rant. This is already the second time I see comments like yours being deleted.

Up to you, but that fix will disable your thunderbolt port. I haven't heard if this fix works or not. My MBP still crashes on occasion, but not nearly with the frequency that it did before.

Which fix are you using? The NoCrashMBP or the driver fix?

Sorry that I wasn't clear. I am running the NoCrashMBP software.

Hi there,

What's the reverse process for this? I.e. when you want to re-enable the Thunderbolt Ethernet Driver? I'm a complete novice:)

Having this exact same issue with a 15" mid 2014 Macbook Pro (2.2GHz I7, Intel Iris Pro) also. Tried all the usual diagnostics including a clean reinstall. I'm on MacOS Sierra.

I'll try to keep it plugged into an external monitor now to see if that makes a difference. If that fixes it then it would possibly point towards an issue with the onboard graphics card.

@view-zwo, @Linus001 and @Jbc30 are you still experiencing these issues? Are you all on mid-2014 Macbook Pro with Iris Pro graphics?

Yes I am still having this issue, although mine is a Late 2013 model running Iris Pro graphics, but I think those are still essentially the same machine. After extensive tests from the folks at my local Apple authorized service provider (and some lovely diagnostic fees) they concluded that it must be a logic board issue. They seemed to be fairly unsure about what the actual issue is though, and when I pressed them on it they just said "sometimes these things just go out" which is barely an answer at all. I can't really shell out the cash to get the logic board replaced right now, and I'm also afraid that the 'diagnosis' may be incorrect anyway.

They did thing there was a possible connection between this issue and the graphics issue with early 2013 MacBook pros that forced a recall, but that it wasn't widespread enough in this model to cause Apple to recall anything.

Interestingly, I have found that when I never put the computer to sleep but instead shut down the machine completely every time I close it, that the issue has not appeared. I don't know why this is the case or if this temporary fix will last, but I've been able to use my computer for the last several weeks doing this and have not had the issue recur while holding to this pattern.

Obviously this isn't an effective permanent fix because its a bit of a pain, but to me its less of a pain than always using it plugged into an external monitor.

I've been running my MBP connected to an external monitor for the last couple of days and it doesn't shut down so that seems to cure the issue. Obviously having it connected to an external monitor all the time negates the benefit of having a portable computer. I'll take it to Apple next week, usually they will fix hardware issues for free if your MacBook was bought in the EU, so fingers crossed.

I had the same problem ... Mine would shut down randomly on me after using it for 10-15 min , and then faster the next time I used it.

The problem might be with the logic board... I got mine replaced and now everything is fine .

Just confirm that I also have the same problem on a MacBookPro11,5.

Been through the complet diagnostics check at Apple and they found nothing but they DID ! confirm that it happened while in their shop. They could not do anything because all diagnostics results of the hardware and software were fine.

Hi everyone Same probleme with same computer Macbook Pro 15 mid 2014, my mac has been shut down randomly for few month now, I've just replaced the retina screen (antireflect issue) I thought my mac would be fixed after that, but no, it keeps going to shut down it makes me crazy ! i've been at the apple store for a diagnostic and they didn't find anything wrong !

I had the same Issue with the same machine.

In the end (I tried almost everything you can think of) I solved the problem by reapplying new thermal paste (Arctic Silver 5).

The shutdowns are caused by too much heat (emergency shut down) because of a bad thermal paste. Mine covered only about 50% of the CPU´s surface.

In fact, the temperatures showing in the temperature tools were not higher than normal, but reapplying thermal paste helped completely.

It´s easy in this model.

There are some youtube videos showing, how to to.

Ifixit is good for it too.
