Macbook pro 16 2019 freezes randomly and restarts

I just bought a new macbook pro 16 inch 2019 that came with Catalina, I set it up as a new mac and installed some apps (Chrome) and started using it.

The problem is it always freezes at some points and I have to manually restart it by pressing the power button for a few seconds until it shuts down.


This might be just me, but I think this shouldn't happen on a laptop thats costs 2699€.

I updated it to the last version of Catalina and this didn't fix the problem.

I wanted to go back to Mojave, not an option I guess.


What is going on Apple?

Darn it ... took too long to post: reposting.


Interestingly I too have a Space Grey MacBook Pro that was "custom".

My specs are: i9 2.3ghz, 32gb Ram, 1TB storage, AMD 5500m 4gb


It took 4 days to troubleshoot but I believe I have a reproducible way to test the Intel 630 UHD GPU issues people are having.


  1. Download Geekbench 5 (I used version 5.1.0)
  2. Select "Later" when the dialog pops up about paying for it. You'll be testing in "Tryout Mode"
  3. Look the the left of the program and you'll select the "Compute" Benchmark
  4. Select Compute API: METAL (OpenCL doesn't error out but Metal does.)
  5. Select Computer Device: Intel UHD 630 Graphics
  6. Open the Console Log app BEFORE YOU run the GEEKBENCH 5 test
  7. Select "Errors and Faults" from the Console log app. It should be at the top.
  8. Start the GeekBench test.
  9. Watch all the red dots proliferate the Console Log app. Most of them will be IntelAccel errors. Many times you will likely see the internal GPU restarting as evidenced by the attached screenshot. Look for signalHardwareError in your logs.

Here is my video of the whole thing. https://youtu.be/Rxh3wATgPOA


During my 7 minute video I try to select the "About the Mac" it takes almost 3 minutes for the window to render while the test is running. You can see in the Activity Monitor in the video it showing as unresponsive.


I truly hope this helps folks - and I wish you all luck. I love Apple and their products. This is obviously something they need to admit and get ahead of because this is turning into something that appears to be a real issue.


My laptop is currently at Apple repair awaiting a logicboard (MLB).


Edited because I hit post too quickly.

My MBP 16" had issues with USB ports back in March, and I couldn't even charge the computer. I sent it to Apple, and they changed the logic board. When I got my MBP back it started to restart every time it went to sleep. I talked to Apple multiple times over the phone about this issue, and they gave me very basic instructions (resetting PRAM and SMC blah blah) and work arounds (disabling power nap, graphic switching, etc). Nothing worked for me, and I wasn't convinced that it was a software issue since I had the same problem on 10.15.15, 10.15.16 BETA, 11 Beta (Big Sur). I basically told the customer rep to set up the repair even if they end up doing nothing since this is a "known software issue". I got my MBP back today with new logic board installed, and I haven't had a single restart so far. Mine was consistently getting GPU Panic, so if yours have the same issue, set up a repair even if they tell you that they might not do anything.

My repaired MBP with new Logic Board came back to me and I got it up and running about a month ago. It has generally functioned smoothly -- I got freezes with some regularity on Teams and Zoom but those were usually only about 15-20 seconds and I could tell that the computer was still working as video/audio /touchbar were still functional so I learned to just be patient and the computer would return to life.


Yesterday, I had my first freeze -> kernal panic since the repair. I was upset, but the computer restarted and booted successfully and thus far it seems to be again behaving normally. From this thread, however, I'm not expecting that this will necessarily continue. I'm not too skilled at reading console logs so its hard to tell if this was GPU related or not but I'm sort of now just waiting for it to happen again, trying to backup my info and dreading having to get this fixed, again, and wondering when Apple will admit that these 16" MBP have real, serious, issues.

I have watched this thread for a few weeks now, I purchased a MBP 16" a few weeks back, this arrived in the beginning of July, nearly fully specced with 64GB Ram and the AMD Radeon Pro 5500M with 8GB of GDDR6 memory and 2.4GHz processor. I had it for less than two weeks and it would crash with alarming regularity, sometimes even when doing no more than hearing music or writing a mail, the fans were coming on like a Jet Engine again, doing nothing demanding. Did an OS reinstallation, wiped disk and reinstalled, reset PRAM and Management systems, pretty much everything, first aid in recovery mode would find nothing but the crashing (sharp intake on the fans and then shut down, sometimes a minute of complete screen freeze, even lost sound on one occasion unplugging headphones and than it crashed) continued regardless of any remedies so was convinced it was a hardware issue. With deadline and work becoming all to urgent, I could not depend on this machine and so sent it back within the allotted 14 days of receiving it. It was my fifth Mac Laptop and was truly disappointed that a machine that cost more than 4K would behave like this out of the box. I acknowledge these things happen from time to time, but the 42 pages that this thread runs would indicate that this is not simply a case of bad luck. It was noted that in my phone call to Apple customer service that a large number of this model were being returned, so Apple really need to get on to this and be a bit humble to accept that something is not right with this machine in a more than is acceptable number.

Here the same problem. Sporadic kernel panics. After I bought MBP 16,1 in Feb this year, had a panic once per 2 weeks or so. Recently 4-5 times per day, in all, normal, safe modes, even in the recovery mode. Reinstalling Catalina, 10.15.6, did not help either. I was able to replicate kernel problem logs while running Geekbench 5, but it did not crash, just 50+ logs...Not sure how the warranty works and what has to be evidenced to ask Apple or a vendor for a replacement. Indeed, paying CHF 2'900 it is a disappointment for 5 crashes per day. Especially, after I had a MBP late 2011 for 9 years, changed logic board once, but all worked fine...

What options do we have if we want an old good stable Macs?


OS: Catalina 10.15.6

Model Name: MacBook Pro

 Model Identifier: MacBookPro16,1

 Processor Name: 8-Core Intel Core i9

 Processor Speed: 2.3 GHz

 Memory: 16 GB

GPU: AMD Radeon Pro 5500M

 VRAM (Total): 4 GB

I was hoping this could be addresses by a software update. It cannot. Mine is for my business. Started July 9 first call. They next day aired a box I sent back arrived Friday returned today before lunch Monday!


new logic board

new ram

new video

touch pad

new ssd


my

machine is only 93 days old and like mint. Used strictly for work. Not moved just taken home. Hardware failure is causing the kernel panics. It is suppressed but still is a broke machine when u manipulate the energy setting for video and power settings. Apple stepped up to the cause. Hope we r good out of the gate. I did not Restore a back up downloaded apps and software like a new machine. Works like a champ. 🙏

I have a MP Pro 16 "i9, yesterday I received it new, and today it started with flickering on the screen, reading the thread I can see that it is a Hardware problem:" Intel UHD 630 Graphics ". I followed what you say and the problem disappeared when use AMD video.


I create a ticket in apple to take my MB Pro to technical service, I want them to change it.

I am having this problem for last 10 months. I got my first MBP16 refunded (it used to freeze several times in an hour) and bought a new one. This does not freeze as often (once in a few weeks) but when I run Geekbench on Intel GPU I get a score of 4516 with lots of errors in the console log. Apple is not accepting this as a proof of any issue with my MBP. What to do? Other issues I face are heating up of the machine during regular use, fast discharge (more than 50% overnight) in sleep mode, and strange blue dots and lines in Chrome and MS teams. Have escalated this to the TOP of the company but no fix till now. It is extremely frustrating using such a faulty machine and not getting any solution from Apple.

i've had my new 2019 mac book for about a week now. before upgrading, i had a 2012 mac book pro that never froze like this. typing this my mac book probably froze 4-5 times and then unfroze. i only have 2 apps open. google chrome and spotify. once it froze and had to restart, kernel panic. this is really unacceptable. i hope apple provides an update so i didn't waste my money.

Sep 16, 2020 5:30 AM in response to fregsfdvbfeg

Have had the issue on 2 separate brand new Mac's now.


The first one I sent back for repair within a month. It's now happening again 4 months later - it's completely unusable for more than 5 minutes and is only 8 months old.


The second one isn't as bad...yet.


This is obviously a massive problem with this machine. Not hearing anyone from apple post any useful fixes here either - seems to me they;re happy to just hedge their bets on you not having any warranty...


Really unimpressed.
