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.

Update: I brought it to the apple store, it passed all diagnostics, they wanted me to wipe the machine and start all over, I said no thanks and returned it. I'm going to wait a few weeks to see if this problem gets any traction from Apple before deciding whether to buy another one. Based on Apple's reaction to previous GPU bugs, they will ignore this until enough pressure is put on through the press and/or threats of class-action lawsuits. We'll see...

Can those with this problem tell me if they are using chrome?

I saw in the console that approximately at the time of my last freeze chrome is generating errors like below :


Wakeups:          45001 wakeups over the last 254 seconds (177 wakeups per second average), exceeding limit of 150 wakeups per second over 300 seconds


Maybe it is related?

I'm having a similar issue. Just browsing the web and occasionally, things completely lock up, for around 20 seconds or so, and then it's like all the commands come flooding in. This has happened to me probably a dozen times, and I only have used this machine a couple of days. I'm not doing anything complicated, at all. The most recent time I was just opening a drop down form on a webpage in Safari. What? Shouldn't thins thing be able to handle me doing that like 10,000 times all at the same time? lol.

Guys. I had the similar issue (https://youtu.be/ZYj9bTTcjIg). The defective one was returned. I am currently using (or testing?) the new replacement.

So far so good with the new replacement. I have no issue. But this time I didn't install the MacOS 10.15.2 Update. The previous one was ok until I installed the MacOS 10.15.2 Update and crashed couple of times during using with eGPU.

Looks like Apple's "Not A Regression" policy on bugs has resulted in a climax of catalina crashes triggered by the introduction of Sidecar, resulting in an inability to sell a macbook that doesn't restart or batteries don't explode.


Piling bugs have actually created a background overhead and array of reasons for the OS to crash, usually surrounding new features like the T2 chip.


Unfortunately on a system such as the macbook pro 2019 16" and perhaps 13", an OS downgrade isn't possible. Since Sidecar was deemed more important than Stability and a lack of regressive bugs, the reaction is to for people to keep returning these things, even though it is not the hardware, it is catalina.


You can't really blame users for refunding either, they have a 14 day not satisfied return window, or a 30 day defective return window. Due to bugs in catalina, the defects become harder to spot, so users with truly defective units that decide to hold on to their macbook perceiving these crashes all to be catalina bugs, end up holding on to a defective unit.


Hopefully apple's hardware quality in these new macbooks is better than the software...still unable to do much on mine apart from use a tiny set of software, but my 2016 13" macbook pro with catalina is doing a whole heap of things and not crashing. The freeze and restart seems to follow a gpu switch.

Just returned my 2nd Macbook Pro 16 inch in 10 days bc both crashed - first one kept coming back to the login screen first day I started using it and after less than 10 minutes with tech support, I was told to return it bc it was "not fixable" -- I returned it and exchanged for new one --- 4 days after using it without problems, it crashed on start up. I called tech support again and was told again to return it. I have had MacBook air since 2013 and haven't had a single issue -- just wanted to upgrade and have more storage, but for $2700, I didn't feel comfortable keeping a machine that obviously has software or hardware issues..... maybe if I wait a few months, Apple will fix the glitches and I can try again

I bought a MBP 16 i9 on 31st of December, first thing it did was freeze, right after I connected a monitor. I got a replacement yesterday, I am actually afraid to do anything on this 3k machine, I got a feeling I will just return it as well within 14 days if there is no update from Apple. I never learn, I bought a new version 4times, and this is the 4th serial problem. It's ridiculous that a premium price tag company is using their users for user testing, but its our fault because we tolerate it and give them even more money. I should just go with Lenovo as I planned.

Same here. Catalina 10.15.1, MacBook Pro (16-inch, 2019), 16 GB.


bought it about 3 weeks ago. Starting from last week, every now and then the screen freezes while the Touch Bar and the keyboard still works. I even managed to stop and replay a YouTube video clip using the touchbar while the screen was freezing for few seconds (the sound was also good). Almost after each freeze I need to restart the computer manually.


Today was horrible - working on PyCharm on a major project and I the computer froze for about 15 times, and I need to press the restart key manually. That actually brought me here to see if there is any recall for these models.


I just want to go back to my old 2012 MacBook Air that had 0 problems.

I really can't believe that I bought this useless expensive machine and that it's preventing me from doing basic computer tasks.

Having the same issues here on 10.15.2 .


Screen completely freezing, sound and Touch Bar working for a brief period. Then FANs rev high and complete shutdown.


Replacement machine has same issue, perhaps GPU Hardware issue? Will Apple resolve with Software patch....


I would expect Apple to have an unusually higher return rate for MBP 16-inch.

I used to get the full-on freezes occasionally, but that seems fixed after I reset NVRAM and SMC.


I am still getting occasional freezes a few times an hour on the integrated GPU only. Just got one now while viewing this thread in Firefox. The screen freezes for 5-10 seconds, but audio continues to play in the background. On longer freezes, I notice that closing the lid and reopening seems to "fix" it.


I tried running with the discrete GPU all day yesterday and experience zero freezes, which really makes me think something is up with the integrated GPU or its driver.


Some folks have thought this may have something to do with graphics card switching, but I installed gfxCardStatus to monitor the card currently in use and haven't seen a correlation between freezing and switching.
