Macbook pro 16 2019 freezes randomly and restarts

Same with me. I started crashing when it went to sleep mode but suddenly it started crashing every 5 minutes. So I took it back to the store and they replaced with another one. So far, so good (after 3 hours of use). LOL. I'll purchase Apple Care for sure.

A fresh full install has been proved useless. Since the latest update 10.15.15 doesn't resolve this issue. The only way is to go to Apple Genius Bar and ask them replace the logic board, and ask them install the MacOS version 10.15.1.

1. Jackhans,

Since you have found this to be the case, I would recommend:

Calling AppleCare and getting a case# for your case.

2. Request that they allow your case# to be shared with others, so they can refer to it.

3. Suggest that people with such cases be allowed to send their Mac in to AppleCare to get the logicboard replaced and reinstalled with 10.15.1 like yours did. Clearly, in the event of COV-ID, the mail in should be possible for such a repair.

4. Let them know 10.15.5 does not solve the problem. This suggests that for people who need 10.15, they will need to use Firefox or Chrome since the latest security is not available on 10.15.1, but is on 10.14.6's latest security update and 10.13.6's latest security update. Perhaps even suggest a version of the security update be made strictly for 10.15.1, until they can figure out why certain logicboards are having trouble with cameras.

I get that this maybe seems unreasonable, but I really just want to Shibboleth and for Apple to forego the whole process of going through their whole AppleCare process, getting forced to downgrade or try other software fixes, going through resetting my SMC and PRAM for the Nth time, leaving me without a computer for days to a week one or several times to replace the logic board, and so on, and just send me a new MacBook Pro, let me image it from TimeMachine, and return the old one.

They have over a hundred billion in the bank and IDK how many tens of thousands I've spent personally on MacBook Pros, PowerBook G4s, MacBook Airs, iPhones, iPads, AirPods, etc, and IDK how many hundreds of thousands they've gotten from me buying those things for my companies and encouraging friends, family, and colleagues to buy their stuff, and IDK how many times I've defended the company putting my reputation on the line saying «they're not over-priced; they're worth it !»

Now I have a ~$5k computer that is broken and my only hope for resolution is to waste hours on the phone and weeks of back and forth and being without a computer under the hope that maybe maybe they'll manage to fix it.

I'm just livid.

My MBP16 has this problem. Fortunately, all AppStores close, and I had to bring my MBP16 to a repair shop, which can formally repair Apple's devices.

My MBP16's problem had physical memory error, so the shop exchanged some parts.

And he said:

1. Only MBP16 with Core i9 has this problem. MBP16 with Core i7 doesn't have this problem. His hypothesis is that program for Core i9 is not enough, especially for external graphic card.

2. My MBP16 had physical memory error, which is permitted by Linux system.

I think that some kernel panic occurred in my MBP16 and its physical memory was harmed, which caused for many kernel panic.

Now I have repaired MBP16, but use it by no sleep mode, no automatic graphics switching (why does it turn on after reboot??). No problem now. But I'm afraid of using MBP16. I think that Apple must compensate our time and mental stress ... !.

Unfortunately that shop was not correct. i7s have had this problem too.

I hope you didn't have to pay for the repair. You do know Apple will send a box to you to send to their repair facilities at no cost to you (at least in the US)?

Ok, so got mine back today from being repaired, new logic board, with 10.15.5 installed and it works totally fine.

So mine was definitely a hardware issue.

Lets see how long it lasts !!

if anything changes over the next couple of months i will report back here.

Cheers

(Replying to myself, see my previous post for context, my 16" MBP was stuck in a reboot loop)

I managed to get the vendor I bought my 16" MBP to issue me a replacement machine with the exact same specs (base everything: i7, 16, 512, 5300). The replacement machine came with 10.15.4; I've since upgraded to 10.15.5 supplemental update. The replacement machine has had no issues at all for over a week now on both 10.15.4 and 10.15.5 unlike my first machine.

My faulty machine was manufactured on week 16 2020 at factory C0. My replacement machine was manufactured on week 20 2020 at factor C0.

As most of you in this thread can imagine, having a machine that you can trust to be stable is a completely different experience than one that can restart on you at any time. It's like having a huge weight lifted off your shoulders. I seriously feel your pain if you're stuck with a broken 16" MBP. The issues described in this thread are definitely hardware issues. I don't understand why Apple doesn't step up and offer completely new replacement devices to those affected by the hardware issues here. If I didn't get so lucky with my vendor (e.g. if I bought directly from Apple) I would have been screwed.

I’m sending mine in today! I reinstalled the OS to make support content it wasn’t the problem. Of course at first you’re like wow everything feels smoother ,but just running geekbench 5 on metal with the intel gpu targeted I get the same intelaccelerator prodding error in the console logs and the fan is back to go 100% definitely send it in. if you have to get a new mac it wont be to big of a deal to setup.

If issues persist after the update and you have correct graphics card, then you have a logicboard issue with the computer. Could be RAM related, and might not even appear under Apple diagnostics, but if you erase and restored the operating system, ran the updater, and it still had an error with Apple only installed software, then I would focus on it being a hardware issue. This is why you purchase AppleCare. As well designed as the machines are anything from a power surge to a spill to an improperly connected or disconnected cable could create issues. You also need to make sure you are using only the correct wattage power brick for make, model, and age of the computer in question. If all that has been ruled out as a cause, then RAM is the probable cause since no test can 100% verify RAM is good, it can only tell you if it is bad.

well - i can duplicate now - if u take the energy saver and manipulate to never sleeping or screen always on where is does not go into a low power, reduced power state it works flawless but this is putting a band-aid on it - If you have anything plugged into the usb-c ports even the power adapter this triggers mine when u have the energy saver set to defaults - if u back up or use any of the usb-c ports like i said even charging this replicates my to freeze or restarts ...... so i have run mine since yesterday with no usb-c ports using anything and no power adapter until needed - charging back from 5% at 37% crashed - hard reboot and 78% crashed got to 100% unplugged and no crashing - just copied the data with apple diagnostic tool and sent to them .....this is not what a new macbook is suppose to be like when i run my business off of it .........just to me sounds like a hardware issue?

@jary144

Evidenced is screen shot log failures while running geek bench 5 , support will ask the “did you reinstall Catalina not from a backup?” If you did and still experiencing the crashing it’s covered under 1 year warranty.

got my logic board done like a month ago and it works like it should right now fingers crossed 🤞

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.

Thanks, I agreed! It's HW! Mind got so bad it wouldn't even start in Safe Mode any longer! That KO criteria for me, back it went, and I couldn't be happier after 2 weeks of ****...

When we’re these established as hardware issues? Me and another friend just started getting these after a Catalina update and turning off power nap fixed it.

Update, i disabled the graphics switching on my MBP 16 on monday rebooted it, and since its not crashed once !

its been on 24x7 since monday no reboots or issues ???

might be just a fluke !!
