#Macbook pro mid 2012 software update high sierra problem upgrade

You can either go to Apple Menu > About This Mac… > Overview Tab > Press System Report…Under Hardware, look for Graphics/Displays….Thanks to them and I combined both their solutions to disable the dGPU on my system. I searched for my particular make with NVIDIA GeForce GT650M Graphics card. However, it was done for older makes (year 2011) of the MBP. In the Apple forums, I saw people had already disabled the on-board dGPU and they had a working system with only the built-in iGPU. Then sometimes it would work for 2/3 days straight, until I don’t open up any BIG IDEs like Intellij or any program like Chrome or Firefox that caused a switch to dGPU. It all then depended on the spirit to re-enter the machine and bring it to life again :)) Many times, it had barely woken up and slipped into coma again. With laptop in comatose mode 😉 I literally had to resuscitate it using SHIFT + OPT + COMMAND + Power (SMC reset) by counting 10 and then do a CMD+OPT+R+P+POWER (NVRAM Reset) and the wait for sometime and power up again. After checking with both the older OS X, I started getting very frequent GPU panics, like the one pasted above. So, I thought may be I should downgrade the OS X to El Capitan or Sierra and rule out my High Sierra upgrade. Secondly, Logic board replacement is an expensive affair! Last option, of course, is to get a new MPB, but I wanted to wait till the WWDC June 2018 announcement.Īnyways, I still wanted to make sure that this is indeed the same GPU problem that I was facing. It had all the possibilities of appearing once more (even after changed GPU).

I thought, if I could get Logic board changed, I should be okay, but in many forums many users who got that done were not still immune from that problem. The machine is a 15″ MBP 10,1 (mid-2012) with dual GPU system. I missed the replacement program (as I was not even aware that it existed until I hit this problem) and now my machine is out of warranty (more than 51/2 years now). So, I started Googling for this GPU Panic problem and found that many laptops had this issue and that many forums said it was all due to a faulty discrete GPU on the logic board.

I got my MacBook cleaned and then it booted fine.

I tried all that, but it refused to work.

I started asking myself why would this happen? Was it due to upgrade to High Sierra 10.13.3 or was it that my machine really developed some hardware problem? I asked a friend of mine what can I do and he suggested SMC Reset followed by PRAM (NVRAM) Reset. After that, many times I would boot straight into Black Screen, and the only sign that the machine was awake could be just tested by pressing the CAPS LOCK key (turns on the button-light) or connecting an External USB with a indicator light. It all started when my MacBook Pro showed me black screen after waking from sleep.
