Macbook pro 16 2019 freezes randomly and restarts

Yeah I've had a few logicboard replacements, followed by a full machine replacement that finally works. As you say Scott, it might not crash but it runs extremely hot at anything more than a browser being opened.

This series of macbooks are probably only going to last 3-4 years then be toast, I can kind of tell because this 2019 mbp gets boiling hot for hardly any reason, but my 2016 doing the exact same stuff doesn't. The fans get so loud I can't make a call through the macbook without myself and caller saying 'huh!'...'what!' cause the machine is so loud.

This is a great example of what happens when a company shifts focus and budget on dealing with a human pandemic instead of their own products, since these machines were released right as covid hit. Joke.

Oh yeah and every time I open an app that activates the GPU (like photoshop), the screen goes black for a few seconds during switch-over. Have formatted my system to get rid of this but it's now a thing ever since 10.15.6...can't win with these machines, $7000 well spent.

Apple also forgot to transfer my applecare from one of my previous mbp 2019's to the latest replacement, forced me to pay for it again. How shocking is that.

What is the expected score when one run Geekbench Metal Benchmark on Intel UHD Graphics 630 card on MBP 16? I am getting a score of 4417. Does it imply that there is a problem with the graphics card?

I'm on this thread, just much earlier. I understand the frustration, since I felt it too. I paid top dollar for a fully spec'ed out machine for work and personal use. After suffering many, many kernel panics and reboots, complete with fans blazing, I finally got an Apple senior engineer on my case. He walked me through downloading a diagnostics package and had it run (~ 15 minutes). I then uploaded a 350 MB file, complete with logs, to Apple. I didn't hear back. But here's the thing -- the kernel panics and reboots just _stopped_. How? It made me wonder if something more than 'diagnostic' happened with the package I ran. It would seem to point to some software issue. At the time I was on 10.15.6. I believe there was an update released afterward. Something strange is going on with these machines. I suspect it is the interaction of Catalina with the new hardware, maybe a driver issue somewhere. But Apple needs to get to the bottom of it for their users.

Since my logic board was replaced (June), I've had a few kernel panics but it *seems* to be getting better. I'm hoping that is due to changes Apple has made in the software -- since if I graphed the crashes against the Catalina updates, as they've updated, the number of crashes has fallen.

My MBP 16" Cataina 10.15.6. is saved!

After 10 month of kernel panic torture my IT colleague found a way out:

There were two or more board partition on the disk, we erase them all and set a brand clean instalation, and...

now it really works!

Yes, Im not 100% sure if helped this or other cause, but after trying E-v-e-r-y-thing, this seems to work.

Hello, I have been experiencing these micro freezes/stutters of my cursor since I bought my Macbook Pro 16'' in June. The problem occurred whenever I was on the integrated Intel GPU.

I thought it would have really been the drivers that caused the issue. But yesterday I tried out Microsoft Edge as a browser as I wanted to have more privacy than with Google Chrome. Since I have completely closed Chrome (not closing the window only and running it in the background!!) the stuttering has disappeared!

I am not sure if shutting down Chrome did the trick... Nevertheless, Chrome is known to be resource intensive and there have been other issues reported with Chrome and this laptop. Maybe some of you can give it a try to elaborate if this is a solution.

Please note, I have also shut down Safari as well and I am using Microsoft Edge as a browser only.

Hope I could help.

I do have the same problem with my MBP 2019 16'-inch.

Specs:

2,3 GHz 8 core Intel Core i9,

16 GB 2667 MHz DDR4,

Intel UHD Graphics 630 1536 MB

Contrary to many people here, it happens even only Safari is open -even with 1 tab-. My quick solution is to close the lid, and then re-open it. It unfreezes automatically.

I still haven't figured out the reason to this problem, but I am looking forward to a solution from Apple with Big Sur.

i had the same problem. After sent back to the vendor, the logic board replaced and since then not a single kernel panic, not a single freeze and the crash report empty. It certainly helped at least for now...

Just wanted to say that this happened to me too on my MacBook Pro (16-inch, 2019) I bought in the middle of 2020. Especially on the initial set up when it is trying to do a a lot of indexing. I think it is a graphics card issue. This seems to go for an uptime after about 21 days and then it goes crazy freezing etc. Shut the thing down for the night and tried it again in the morning and seems to be going ok again. It would start ok in safe mode. Even when I tried a diagnostic it says all is ok. I have taken photos of the screen various time when it freezes too.

I HAD exactly the same issue with my 2019 MacBook Pro 16, Intel i9 2.3GHz, 1 TB SSD, Intel UHD Graphics 630 1536 MB, AMD Radeon Pro 5500M 8 GB.

Stuttering while typing, watching videos, simply scrolling a web page...

Switching to the dedicated graphics card makes it much better but drastically reduces battery life.

Then I found https://chromeisbad.com. I had Chrome installed on my system but was only using Safari. I followed the steps to completely uninstall Chrome and the stuttering problem immediately went away.

This is unbelievable. We all were blaming Apple for bad graphic card drivers, returning hardware and so on...

The problem is caused by Googles keystone stuff which is always active even if you are not using chrome.

Give it a try and please report here if that helps you too.

I'm so happy my MacBook is running smooth now!

Had the same issue with my new macbook , a week after I purchased . I gave it to the customer care of apple with recording of my issue . Initially , they couldn't find the issue but later they understood my issue and changed the logic board with RAM under apple care protection plan. Now it's working fine

There may be software issues as well (though anything in Chrome that could cause such an issue is still an issue with macOS), but I'm quite confident there is at least one if not more hardware issues with some if not all of these MacBook Pros

Ohh I had to have my motherboard replaced back in may , it’s been fine ever since but chrome has also been causing issues ever since they removed the metal flag from the latest version , I get blue lines when it’s trying to use hardware acceleration .

I always thought it was a software issue (and in the deep of my heart I still do) but three weeks ago I finally decided to take the my mbp to apple care. They finally replaced logic board including memory, processors and hard drive.

Of course the first thing I tried was doing something that enables the discrete gpu by attaching a second screen, open an Adobe software and doing GPU benchmark with Metal API in Geekbench 5, all things that were causing display freezes and reboots.

With gfxCardStatus I saw that the external GPU was actually activated everytime and I don't experienced any freeze, any reboots and any glitches, even on Chrome.

I still don't know what was the problem but I'd bet a dime to a bad update, maybe back in december 2019, that downloaded faulty drives for the external graphic card and this caused those hardware issues.

I wanted to share my experience, hoping I will never need to post again into this thread.

FYI my setup is:

MBP 16-in, 2019

2.3 GHz Intel core i9 8 core

32 GB 2667 MHz DDR4

Intel UHD Graphics 630 1536 MB

AMD Radeon Pro 5500M 4GB

MacOS Catalina 10.15.7

My 16" 2019 MacBook Pro with 16 gigs RAM freezes and give me an out of system memory error when I am mirroring my display to my Apple TV and I try to view an image in Photos. Happened 3 times before I gave up trying to use it for that.

Touchpad and everything becomes unresponsive and I have to manually reboot.
