I have MacBook Pro Retina Mid 2014 with Catalina installed. Initially my Mac is randomly shut down and later it shutdown every time I logged on to the Mac. It will display the desktop for a few seconds then shut down.

The Mac keeps shutting down in the Safe mode and also Recovery mode. But when I run Apple Diagnostic it says that there no errors found.

When I look in the log from advice in comments, I get "shutdown cause -128"

Do you think my logic board is broken or this is related to something else?

  • This might be a Hardware Failure issue but before tampering with that, try resetting the NVRAM/PRAM and SMC. Check out the two Apple Support articles showing how to do that. support.apple.com/en-us/HT204063. support.apple.com/en-us/HT201295 – Todd Apr 29 '20 at 14:12

  • @Allan I've tried it before and it returned -128. Anyway I'm gonna try solution described here apple.stackexchange.com/questions/306714/… – webchun Apr 30 '20 at 13:03
  • -128 is hardware. Disabling protection is the OS isn't going to fix what's inherently wrong with your Mac. Check your memory - see: apple.stackexchange.com/a/212810/119271. If that's not it, you need to take it in for service. – Allan Apr 30 '20 at 13:05
  • Thanks for all links @Allan I'll try it one by one – webchun Apr 30 '20 at 13:20

This could be a Hardware issue.

But you have these options that can help:

1) Reset your Mac's NVRAM or PRAM.

2) If you continuing experiences issues, try to reset the SMC of your Mac.

I hope that works.
