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.

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 brought me to some sort of check. It said: nothing is wrong.

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

選択されたソリューション

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.

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.

by

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...

by

@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...

by

@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 had this issue on a mid 2014, 15” MacbookPro (11,2), under OS X 10.11, 12 and 13.

Both renaming the kernel extension and running the python script worked.

However, just inactivating the service also worked for me.

In the Network control panel, select the thunderbolt bridge connection(s) and make the service(s) inactive from the options drop-down menu, at the bottom of the frame.

Whenever you need a wired connection through thunderbolt, activate the service and do your work (running the python script at these times to avoid crashes). When done, inactivate again.

BTW if you boot to recovery partition (CMD+R), renaming AppleThunderboltNHI.kext does not require inactivation of the system integrity protection through csrutil or issuing commands as sudo (since you run as root). I you just need to navigate (with the `cd’ command) to your main HD extensions folder (usually /Volumes/Macintosh\ HD/System/Library/Extensions/) and rename (with the `mv’ command) AppleThunderboltNHI.kext . If you can boot your mac from another partition, internal or external, you can do that through the Finder.

I have been using the kernel extension and occasionally the python script. But with Catalina haven't figured out how to do the rename. So went to the python script all the time. I just came across this post and hoped that making the thunderbolt bridge inactive would do the trick but no luck. Stuck with the python script for now.

BEWARE!

Driver fix will not be applicable with Catalina. When you install Catalina, It partitions the disk into 2 and save the OS on a Read Only partition. You can’t change driver to .bak. I will try disabling or removing Thunderbolt on Network and let you guys know.

Hi, have you solved the problem? Just about to upgrade to Catalina, sounds like I shouldn't? I suppose I've got more life out of this machine that I should have expected, maybe its time to get a new one.

by

In Catlina, before rename the file, run it: sudo mount -uw /

It will let you rename the file.

Thanks -- saved my bacon again after Catalina upgrade!

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.

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

@marckrone i never received a screenshot but I followed the instructions on this forum on how to remove the applethunderbolt extensions and it ONE HUNDRED PERCENT cleared random shutdowns! I definitely recommend you try that. I don’t even use the python thing anymore. Goodluck!

by

I have no idea if this is correct - but I looked up some python tutorials - and this is what I changed my script to:

----------------

import time

while True:

time.sleep(0.0005)

----------------

Can somebody confirm - is this how it should look?

Thanks!

Okay ladies and gentlemen after 4 months of testing I have isolated the issue.

  • Updated to Mojave problem still persisted
  • Removed Thunderbolt port in Network Preferences problem still persisted
  • Reset PRAM problem still persisted
  • Reset SMC problem still persisted
  • Took my MBP to the genius bar, all hardware passed diagnostics problem still persisted
  • Took my MBP to mac specialist, said it was a software issue or logic board issue. roll back OS to previous state problem still persisted.
  • Rolled back to previous state problem still persisted
  • Rolled back to Mavericks original factory OS problem still persisted

3 things that could be wrong after this troubleshooting:

  1. CPU Core voltage is causing the random shutdown
  2. iGPU is bad (requires logic board replacement)
  3. Logic board needs to be replaced

Before throwing in the towel to replace the logic board I attempted to try to code the python script posted by Anders Wiggers myself with no success as I ‘ not a coder and spent 3 hours wrecking my brain. so I decided to use the Mac-Mods software for $10 and ran the software which creates a gear spinning on the bar and voila the laptop no longer randomly shuts down!

Updated to Mojave and just an FYI the gear is no longer in the bar but the laptop does not randomly shut down.

The problem is CPU core voltage related which is corrected by the python script or the Mac-Mods software for $10. if this does not work it is most likely a logic board issue.

Good Luck

Random Shutdown Fix

You can prevent the random shutdown by connecting any device to the Thunderbolt port. Don't have one, then do the following:

Boot to recovery:

1. Click on Apple logo at the top left of the screen.

2. Select Restart.

3. Immediately hold down the Command and R keys until you see an Apple logo or spinning globe. You will see the spinning globe if the Mac is trying to start macOS Recovery via the internet because it is unable to start from the built-in recovery system.

Open Terminal :

1. Type csrutil disable and press return.

2. Reboot

3. Open terminal

4. go to /System/Library/Extensions

5. sudo su

6. enter the user pwd

7. type "mv AppleThunderboltNHI.kext AppleThunderboltNHI.kext.BAK"

8. Reboot to recovery

9. Open the terminal

Hi. Guess I get to join the party. My late 2013 MBP 15 has been shutting down. Using High Sierra.

I tried a lot of the suggested fixes I could find online with no success.

It would run ok and not crash if I had my audio hardware plugged into thunderbolt. If I unplugged, it would crash in a matter of minutes. I turned off the Thunderbolt /Ethernet ports in Sys Pref, and that seemed to work for a while. But, instead of entering sleep mode, it would shut down. Thought it was working enough to bring it to work (where I dont have a TB device) and it shut down within minutes of turning it on. UGH!

Currently, I have the TB/Ethernet ports set back to “using DHCP”, but I decided to shut off my wifi (I’m currently typing on my work PC). My Mac is currently not shutting down, until I turned the wifi back on, then it shuts off in minutes.

So, no TB plugged in and wifi OFF and machine acting stable. I’m curious if anyone else has had things stabilize by turning off wifi. And further, what this means for me and my MBP.

Thanks

Closed my MBP last night. It shut down at some point. Had 4 failed boot attempts to start the day! Command D got me booted and working (TB plugged in still). At work, I have no TB device here to plug in. MB crashing in less than a minute. Turned wifi off, no more shut down. On a whim, I tried Renew DHCP Lease for Wifi in Network Preferences. No crash for about 15 minutes. Rebooted, and went back in to Renew DHCP Lease for wifi. Hasn't shut down in two hours.

For whatever reason putting my flash drive in the USB slot fixes the problem. o.0 I havn’t tried the wifi thing yet, but that sounds interesting.

OH MY GOD! IT WORKS!! I got my MBP to repair store and they put a new motherboard in it, after that I got a new external SSD for backups for my MBP and random shutdowns didn't appear for a long time. But then I needed to use my MBP out of home so I plugged out SSD then call my wife and MPB shut down in few mins, I thought that problem reoccur and didn't realize that I got it fixed by plugging in my back up SSD!! HUGE THX for your comment. I can't believe that the solution was THAT SIMPLE!

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.

In reply to the past comments about random shutdowns with MacBook Pro late 2013, I also have this experience and I think I have solved it, at least on my MacBook. . My MacBook Pro experiences this random shutdown, and has been for many months, however only in High Sierra. I also boot camp into windows this shutdown does not occur when in Windows in Bootcamp. I erased the entire drive and installed El Capitan and I have not had a random shutdown since then.

there might be a lot of reasons for that.

It might be due to physical power cord or motherboard or power supply.

Better to visit and consult some local support shop.

If you want to figure out this on your own, then you have to diagnose the problem, you will have to try different things.

You have to try to Reset your MacBook (follow this decent article on the internet for that https://www.experthoot.com/how-to-reset-...)

You have to try to pull out and pull in the battery(yes you will have to open your MacBook)

SOLUTION FOUND! I have a MacBook pro with the same issue. I found connecting and external monitor or TV with the HDMI cable corrects the issue. Then I purchased a CompuLab Display Emulaor on Amazon for $8.50. It's a small dongle you connect to your HDMI port. It fools the laptop into believing it has an external monitor connected. Better than an $1100.00 board. I put the link below. https://www.amazon.com/gp/product/B00FLZ...

P.S. I tried all of the solutions out there and none of them worked for me.

My Macbook Pro 2013 had the same problem. But then I found this free python scripts with explanation:

https://www.reddit.com/r/mac/comments/9p...

and after some month of terrible problems and an increasing frequency of random shutdowns my mackbook runs the first time without charger and any shutdown. I almost cannot believe it...

Now since 20 days it works absolutely well. I can use it as before the problem appeared. Even the weak battery (from permanently charging for a few month) works very well again.

I can really recommend this simple solution.

Hi everyone.

Im running Mojave on my MacBook Pro 13” Mid 2014.

Im still having random shutdowns, even though that I have tried all the following solutions:

NoCrashMBP (RealMacMods) as well as another 3 level no crash python script, from a German Mac/computer specialist workshop.

Pythonscript from Anders Wigger

Moving the AppleThunderboltNHI.kext file

I have even put in a new fan with new thermal paste on.

I’m now using Macs Fan Control as I noticed that the fan ran at 1399rpm as a default, and It didn’t increase in speed when I did CPU heavy tasks.

I now simply have no clue, to what my next step should be to resolve this quite annoying issue. 

I’ve tried to get a crash report, when it shuts down, but as far as I am concerned I can’t get any or find the location of it. 

Does any of you have any experiences to share regarding my situation?
