Recurring Freeze and Shutdown (MacBook Pro late 2016, No Touch Bar)
MacBook Pro (13-inch, 2016, 2 TBT3)
Now on Catalina, issue first appeared on Sierra
I have this recurring problem on my Mac. I brought it to Apple several times, each time they changed the topcase which didn’t help the issue. Now they don’t want to do anything anymore without me paying as it’s out of warranty. I am very disappointed as I’ve never been able to enjoy my Mac at all.
The problem is the following:
My MacBook pro suddenly freezes and then shutdown. If I turn it back on it says “Your Mac Shutdown because of a problem” And I can either reopen all apps or not, but I don’t have the diagnosis option.
It becomes more and more frequent as I use it. In other words the issue comes faster and faster after the mac is turned on.
For example if I don’t use my mac for 1 week and that I turn it on, it can go without freezing and shutting down for 3/4 hours. After the first freeze and shutdown, the second come like 45 minutes afterwards. If I turn it on a third time after the second freeze and shutdown, it will only work for 20mn before freezing and shutting down again. And so on. About halfway through the day it just freeze and crash before I can even type my password to access my desktop, which makes the machine unusable at all for the day.
I tried unsuccessfully the followings:
I tried to reset NVRAM
I tried to erase the disk and then reinstall MacOS from the recovery partition
I was on High Sierra, I tried to update to Catalina through the internet recovery mode, (CMD OPT R), the update happened but issue still is here
I tried (sort of) successfully the followings:
Any idea to help is very welcome! :)
Thank you in Advance,
Thanks for getting back to me.
1) Unfortunately I do not get the prompt window where I can have the report. This is because the computer shutdown (It doesn’t restart). The only prompt window I have asks if I want to open what was open when it shutdown.
2) They did not replace the logic board. This is because when they do a hardware diagnosis, all components show up OK. (I did one myself too and it was all fine)
3) Unfortunately, my mac is not eligible for the SSD program because it wasn’t purchase in 2017 but in 2016, when apparently units were not affected. I’ll try to be more insisting when I go back, thanks!
4) I want to explore the “Safe Mode” aspect, it doesn’t shutdown at all in “Safe Mode” (I let it run 4k video overnight and it was still running in the morning). My understanding is that if it works fine in “Safe Mode”, it means something that is activated during Normal Mode but that is not activated during safe mode is responsible. How could I test these elements one by one ? The responsible could be something I don’t care much about like location or bluetooth …
Thanks again guys!
