News from my MBP: It's still in repair and the repair shop confirms a hardware failure. System crash (black screen, fans blow up, reboot immediately) when switch to 5500M GPU, probably this switch doesn't occure in safe-mode. The system crash even in Apple advance diagnostic program (from a netboot image), the built-in diagnostic (press D on boot) doesn't report any error.


Result: A new logic board from apple is on the way and I should get back my MBP next week.


(MBP 16inch, 2.3i9, 64G Ram, 2TB SSD, GPU 5500M 8GB)

By today, I got my 2nd replacement both had the same issue or similar . I purchased the first Macbook Pro 15 inch , Max specs in May 2019 and I started experiencing crashes a week after and it kept getting more frequent. it took Apple till Nov to believe me and finally give me a new one. I got the 1 replacement in Nov 2019 and went about my business and Today 02/07/2020 , the first replacement keep restarting and crashing . I took it to the apple store and it did it in front of them and they gave me a new replacement.


I'm currently on 2nd replacement and hoping not to ever go back to the Apple store again and deal with this. I been a Mac user since 1997 and I never doubted their reliability but now days after Steve Job passed away things are just not the same quality as they use to be.

Hello Everybody !


I have the same problem. I have a Macbook Pro 16", 2019 for just one week and start having problems.

The problem is the same you have all tell in this post.


I don't understand why apple haven't fixed it yet. I mean, this is a very high end laptop that is bought by demanding people that want the best in a equipment, customer service and technical service, and certainly apple is not delivering it...


I really hope this can be solve ASAP.

Same issue .See above a subset of the stack trace which is sent to apple after reboot.

Are they going to contact me to ship me a new computer as a replacement ? Computer is a high end Mac which is couple of months old ,apple care ,32GB of memory..... I thought it will be better than the one that I bought in 2018. ,I have had 3 times the logic board replaced.

Prior those 2 ,I also had a computer who died from the same thing logic board.I did not fix it.

My daughter has a Mac pro as well .Logic board died got replaced after apple care expired. I paid for it.

Mr Apple support ,please look at the history of the Mac which are registered to my ID and the history of the repairs.

Likely ,the new one has the same issue....Logic board need to be replaced....

Will you be shipping 2 new computers to me for the new one that I bought a couple of months ago ,for the one bought in 2018 and I don't count the one that I paid for my daughter or the previous one which is sitting on a shelf because the logic board did not get fixed.


You have my contact information .You have the history of my purchase .You have the history of the crash because they get sent to you ....


What can you do for me when I spent more than $10.000 in computers in the past couple of years ?
