My Mid-2014 15" MBP has been randomly crashing and I haven't been able to identify a pattern to the crashes.

Here's a log right after a crash and automatic restart:

I followed the troubleshooting suggestions in comments, but the disk appears to be ok. Is there anything else I can do myself before heading to an Apple Store? (The MBP is out of warranty)

  • First thing to do is search to see if this question has already been asked. Secondly, when phrasing a question it's important to provide specifics like what version of macOS you are using. Details are important, as we aren't there to look over your shoulder. – Allan Aug 30 '17 at 10:16
  • Of course I did a search first and didn't find a thread similar to my situation. In the attached log you can find all the necessary info. – Modestos Kaffes Aug 30 '17 at 10:19
  • Interesting...Doing a Bing search, I found this link (very first link). Try the diagnostic procedures outlined in the answer there. – Allan Aug 30 '17 at 10:25
  • The fact that you are experienced in debugging mac crash logs doesn't mean all of us are. You may know immediately where to look in a file full of random numbers, but I don't. If you want to be a helpful member of the community, show some empathy and cut the ironic talk. Other than that, thanks for pointing me out to the correct (I hope) direction. – Modestos Kaffes Aug 30 '17 at 10:30
  • Don't do that. Searching for "initproc exited " in the line right after "Panic Report" would bring up a slew of info including that link. Our How to Ask in the Help Section specifically details this. Finally, you asked for a "direction," does the term "error" in the log not fit that qualification? – Allan Aug 30 '17 at 10:37

What you are experiencing is called a “kernel panic”.

The line Root disk errors: "Could not recover SATA HDD after 5 attempts. Terminating."is a clear indication of your MacBook having an issue with the built-in SSD. Are you sure you had a look at the results of Disk First Aid, preferably run from the Recovery HD? As an alternative, you might want to boot into single-user mode (pressing cmd-S upon start) and use fsck to test the drive:

fsck -f

Use the reboot command once fsck has finished.

Has the MBP ever been opened or dropped? In that case, the SSD may just sit improperly in its slot which would explain the intermittent nature of the symptom. Unlikely but not impossible.

  • - Running Apple Diagnostics returns: No issues found Reference code: ADP000 - Running First Aid from Recovery (Verify/Repair) returns: The volume Macintosh HD appears to be OK - Running fsck -f returns: The volume Macintosh HD appears to be OK (after all the checks) The MBP has been taken really good care of and was chiefly used on a work desk for about a year and a half. I wouldn't suppose this is an issue of mistreatment. – Modestos Kaffes Aug 30 '17 at 14:48
  • In this case it might be worth taking a full backup, completely erasing the disk and restoring from the backup taken previously. Not something done with levity, though. – Tom E Aug 30 '17 at 14:56
  • Should have mentioned it in the original post but I've already done this. I've also completely formatted the disk and cleanly installed macOS but it still froze. It even froze in a Windows bootcamp installation. The problem is I cannot reproduce it. It happens randomly (hence the question title), that's why I'm looking for a way to understand what's the issue, so if I was to take it to the store, to give them some heads-up and not have it returned with the claim "It works perfectly". – Modestos Kaffes Aug 30 '17 at 15:42
  • @ModestosKaffes I'm having the same issue as you. So far everything seems to be pointing to either the SSD itself or the onboard controller being faulty. Have you tried installing macOS on an external drive and seeing if the problem arises again? Alas, there doesn't seem to be anyone with a definitive solution to this issue. – Najm Sheikh Aug 30 '17 at 17:25
  • Also are the S.M.A.R.T readings showing up any errors? – Najm Sheikh Aug 30 '17 at 17:27

Digging up this old question to add an answer, as it might help someone in the future.

What did the trick was to take the MacBook to a 3rd-party repair shop, where they took the internals apart and cleaned the SSD connection to the motherboard. After that I’ve been using the laptop for the past 2 months with not a single freeze 🤞.

However, the above begs the question how did the SSD connection get dirty? But let’s leave it at that.
