Random Shutdown on Macbook Pro (15" mid 2014)

i have a Macbook Pro (Retina, 15', Mitte 2014) with El Capitan installed (10.11.6 (15G1004)).

It keeps randomly shutting down. This happens like this:

1. Screen turns black (does not turn off, logo-light is still on)

2. Fans accelerate,

3. After 5-10 secods, it turns off (screen & apple-logo turns off)

4. i can boot normally. no crash report.

I was not yet able to reproduce the problem. ive tried a lot:

- happens with or without power cord plugged in

- resetting the smc does not change anything

- reinstalling OSX does not change anything

- it feels like it happens mostly when having high CPU Usage, but running a benchmark (cinebench) to put pressure on the CPU does not automatically shut it down

- also happens with no CPU Usage at all (but fewer times)

What diagnostics can i provide to give you more detail?

What monitor tools are available to get more information about what happens?

Anybody encountered this... ever?

I'd appreciate your help!

MacBook Pro with Retina display, OS X El Capitan (10.11.6)

Hi Dennis,

Interesting! And thanks for pointing out the differences.

I solve the problem by disabling the Thunderbolt Ethernet Driver, by following the procedures:

1) reboot with CMD+R pressed.

2) open Terminal

3) sudo csrutil disable

4) reboot in normal mode

5) sudo mv /System/Library/Extensions/AppleThunderboltNHI.kext

/System/Library/Extensions/AppleThunderboltNHI.kext.BAK

6) reboot with CMD+R pressed

7) csrutil enable

8) reboot and forget about problem

Now I could not use the Thunderbolt Ethernet (which is quite troublesome when I must connect to the Ethernet). My interpretation is that there are some problems with the Thunderbolt Ethernet Driver. When I do not connect the cable, the driver may check for something related to Ethernet and crashes the OS, while I'm connecting the Thunderbolt Ethernet, everything goes fine.

No matter I turn on or off the WiFi, it stays the same. So I think it may not related to the WiFi.

THANKS FOR THE TIP!!

Hey, question about the patch,

What happens after you pay? I paid and there is no download link, does it **** on physical drive?

Thanks again

hmm.. Well then I prefer having a little less battery life to a partially disabled laptop.

Is your laptop running High Sierra? Was the issue observed on Sierra?

The issue is with Apple MBP2014. Please read the threads.

No it first started almost 2 years ago. So yosemitie? Now it started the second time (new logic board) on Sierra. I did a clean install of high sierra, but the problem persisted.

Will using the thunderbolt ports with a firewire cable still work after this 'fix'? Or is it only ethernet that's disabled? I use some soundcards and they all use firewire.

Try and tell us. Anyway you shouldnt delete kext, just rename. And if you want, rename back.

Very interesting! Thanks.

I should say, that fix with kext removal is significantly better from power consumption point of view, than nocrashmbp. My laptop was on 60 deg on idle with
