MacBook Pro Shuts down randomly

Two days ago I wanted to continue with my video project on my MacBook Pro. I opened it (I don't shut it down) and it was off. I thought maybe the battery was dead and I didn't charge it.

So, when I put my MacBook in the charger and click the on button it went on for 5 sec and then turned off. I pushed the button again and now I could login I looked at the battery it was still 80% so I thought that's odd.

Then when I logged in it shuts off again. I've tried for several times to turn it back on sometimes it didn't even turn on and sometimes it turns on and then it shuts off again after seconds.

I went to a computer store but they didn't know what was going on the guy said that he couldn't find anything weird in my MacBook (software) yes of course when the guy looked at it it worked. Until it suddenly shuts down and I was like: 'Yes that's the problem!' But he had no clue. All he said was: 'send it back to apple'

So another thing: I'm traveling and need my MacBook for my work (I'm a colorist and work in the film industry) I need it everyday.

Maybe something important: last June I Accidentally closed my MacBook with the charger between so my display broke. I replaced it, cost me lots of money, and then after 2 months it was loose (I haven't fixed it yet, been more than one month now)

I can move my display up and down for at least 1cm. I can also detach the black bar underneath the display from the display, think this used to be glued together.

I don't know if this might be the problem from the MacBook shutting down randomly.

Ps. Sometimes my MacBook doesn't shut off completely and the fans start making extreme noises. It's like my MacBook is frozen.

MacBook Pro:

Mid 2015 with Retina display

2,5 years old

Used daily

MacOS Sierra

UPDATE:

I've turned it on again and clicked the D that broth me to some sort of check. It said: nothing is wrong.

Now it just restarts randomly. It's better but still not 100%

I just started the petition "Apple: Apple Macbook Random Shutdown Syndrome" and wanted to see if you could help by adding your name.

My goal is to reach 100 signatures and I need more support. You can read more and sign the petition here:

Hey Ruan. Just signed on for Real Mac Mods. I highly recommend you add a goal or mission for your petition. You lay out the issue well, but what do you want your 100 signatures to accomplish?

The problem should be solved once you turn off buggy Thunderbolt LAN Ethernet driver. Here are the steps:

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

Solution has been taken from one of the forums. That's personally helped me with my mid14 macbook pro Retina 15

UPD: How did I find this

I have the same issue with random "silent" shutdowns. Mac randomly turned off with the screen on, fans started to work at max level. Few repair services tried to diagnose the problem but unsuccessfully. All the times diagnostics showed "all is ok, maybe battery". I have replaced the battery but issue was still there. In the 4th repair service engineer found out the issue with voltage: with some random load on computer voltage on motherboard was going down from 12V to 11,5, 11.2 or even 10V and after this macbook was crashing. The only possible solution as I was said by the service is to replace the motherboard.

However, macbook was working perfectly when I connected external monitor. I have started to search through the forums and finally found people with the same problems and solution was found here: https://forums.macrumors.com/threads/hel...

Good luck guys. I wish you could save your macbooks too!

P.S. Another possible solution is to use the python script which you could also find by the link at the top. If I understand properly, it generates some specific load which keeps voltage at normal level. However script slightly affects on performance and battery life without plug.

This did not solve my issues but pointed me in the right direction.

por

This should be the correct solution for me as I witnessed the problem reoccur after a Mac update and the kext file was “fixed” back by system and immediately recreates the problem. How smart Apple is.

por

What is the right direction @dusten?

I have the same problem and I get the error no such file or directory when I attempt to rename...

por

@yalematta did you go to the folder provided in the solution to see whether it was really there? The buggy kext should exist if you are using the updated macOS...

por

@yalematta I found in reading the thread that also just going into the Network Preferences and deleting all the thunderbolt adapters solved my issue.

I started with the instructions above with moving the driver and what not but that didn't solve it for me.

Being that I work almost 100% wireless deleting all the unused Ethernet Interfaces and only leaving the wireless and Bluetooth stopped the random shutdowns.

I found that the Python script fixed the problem for me, I made a guide on my site if you need help setting it up.

THANK YOU! This worked... it is a little difficult for those of us who have zero coding experience whatsoever ( that copy paste isnt exactly right you have to slightly change it...took my 2 hours to figure that part out) but again THANKS because I had given up on my machine and THIS saved me.

por

I have zero coding experience are you able to copy paste the code you used exactly.

por

I can send a screenshot to your email... because also there are two other things I had to change from the post like that arguments button I had to keep playing with it until I got it right @ethandelacy

por

@ Blizm “K100” PD Can you please the screen shot of the same. I would like to use it. Please use chakri161616@gmail.com

por

@chakravarthy I sent it to you. Hope that helps, mines hasnt shut off since I got that working. Good Luck .

This article lists some possible fixes.

There is also a lot of discussion about what the problem was, possible solutions, attempted solutions, etc in this thread: MBP turns off Randomly Without Warning. You might find other options in there if nothing in the first link works.

Good luck!

Click on the Apple logo in the menu bar. Then, click on About This Mac > System Report > Power. In the Health Information section, see if the condition says "Service Battery."

Super common issue that is presenting it self on tons of 15" and 13" MacBook Pro's in the past couple months.

This will absolutely stop the random shutdowns/restarts

From your description, it seems the Python loop/sleep script mentioned elsewhere. Honestly, 10$ for something so simple that anyone can get elsewhere, isn't very honest.

I do not think the issue resides with the battery at all. Apple products are know to do stupid $@$* to "protect " their devices. Sometimes your computer does stupid things from the humidity being a little to high for this delicate expensive device and trips a fuse. That being said a fuse in your motherboard could be fried and it keeps get tripped and it shuts down your computer. So this might need a full replacement of the mother board but I do not know for sure. Get a reliable repair person to check if this the case. This repair might cost half as much of the computer so I think it might be in your best interest to buy a new computer if this is the case. This repair could be very cheap though if the person just needs to replace the fuse and nothing else.

The issues is the U8900 chip on the logic board more than likely. Send it to Device Pro Solutions and we'll get it fixed up for you!

Actually disregard this thought you had a 2012. If a 2015 is doing that, take that to Apple and yell at them that shouldn't be happening.
