Hi Everyone i am getting the error below and my computer wont login. i have the new 2019 16in its less than 3 . weeks . old.

I am having the same issue. When I reboot the progress bar gets to about 70% and then the fans whir for about 1 second then the machine restarts and it just keeps doing it. When I restart in safe mode I get this error report.

Same problem here. Started happening 1 time per day and now its multiple times. Seems to happen only when awaking form sleep.

Let us know if the new one fixed it. Im hoping this is not hardware related and I will have to go through the headache of replacing this.

Okay so this is the error message I've been getting:

I was replying back to @philux who provided an EtreCheck report showing the use of CMM. If you read my reply I also said I doubted CMM was causing this particular issue since so many people have reported the GPU panics with the MBP 16". Suggesting to remove CMM was to help @philux specifically to minimize future issues since CMM has been shown to cause problems with peoples' Macs (just search these forums for how many systems are fixed just by removing CMM).

Right... but if you read my responses, you would note that CMM had

nothing to do with it. It was removed with zero impact. In fact Apple

Engineering wanted Dropbox removed... yes Dropbox strangely enough. So

there is no need to explain.

Similar issue here, differences bolded:

Ok, I do NOT have a MBP 16"...I have a 2012 MBP 15" and I have the same issue. If its not plugged in, it tends to crash on wake from sleep. It does occasionally do it while plugged in but majority is when on battery.

I just did a fresh install of Catalina. I had been experiencing the rapid restarting. With a fresh install, It ran better...for about a day.

Backstory. I bought this used off of Mac of all Trades. It had a new motherboard about 16 months ago.... \

Oh, I did notice when I signed into Adobe CC, the processor started working really hard and it would shut down.

I am going to try not letting it go to sleep... the gestapo method of computer using.

Same here. Absolute joke of a company - support were so rude. Casually saying to reinstall everything to test when I just paid my engineer £600 to install every music plugin i have all of which would need licensing again and took days to set up / let alone multiple final cut pro projects on the go that are a pain to move. The exact same thing happened last year with a maxed out MBP and after months of fighting they refunded. This time they basically said 'do one' - Awful support - when is a rival company just going to come out with a competitive product that is actually well-made. Every time I close the machine it restarts, sometimes turns off mid work flow, screen going weird, touchbar not working randomly, DO NOT TOUCH THE 16 INCH MACBOOK PRO. I don't know about anyone else, but if this (laptop) is your only way to work why do apple assume we can all go without a machine for 2 weeks to get it repaired? Especially After 5 weeks of being brand new machine and costing 6k. Joke of a company. Steve jobs would be ashamed. If your porche or even skoda started cutting out on the motorway after 5 weeks they would bend over backwards.

I don’t have the luxury of Apple care on this 8 year old MBP, which worked great until Catalina

hmmm... are they trying to make me update?

This thread is for issues with the 2019 16" model and from all accounts it looks like the 16" MBPro 2019 has an actual hardware issue. Since you do not have this computer please start your own thread with the pertinent details if you want assistance from the community on sorting out the issue with your laptop. You may want to run EtreCheck and post the report to these forums in your own thread using the "Additional Text" icon which looks like a piece of paper.

Well since I am having the SAME issue I thought I might try to help you figure it out by showing you what mine is doing. ESP since I probably have a motherboard from 2016

stop being so snooty. Ignore me if you don’t agree

Thanks for letting us know what your [different model] is doing, but the computer that was just released is unlikely to be showing exactly the same issues as yours, even if the symptoms are the same.

You would be far, far better off starting your own thread to get a solution for yourself.

There are several other threads, one with over 36 PAGES of posts about the new 16-in MacBook Pro. Your issue about a different computer is unlikely to be relevant to THIS discussion, being held in the Hardware area for MacBook Pro.

If you think this is a Catalina problem, please start your new thread in the Catalina forums.

Ugh... I was about to try this. I'll give it a shot anyway. I'm speaking with someone who just had their logic board and touch ID replaced. Having him try to induce the crash.

Next step is to try turning off everything I can in pmset.

Yep. That reproduced it. Interestingly I am not seeing PowerPlay in the problem report log this time. But still have IOGraphicsFamily and AMDRadeonX6000 showing up in the extension backtrace.

I had auto gfx switching off, which seemed to help earlier but apparently that didn't fix it. At least I know how to trigger it now for when I inevitably take this to the store.

Just tried this again but in safe mode (where the GPU isn't used?), and I couldn't reproduce the problem. So definitely gpu-related. Now is it drivers or hardware?

Does anyone have Bootcamp running? I wonder if it does this in Windows.

"Solution" was probably the wrong word there. I just spent a lot of money on this, so I'm not going to accept turning off a feature, "crippling" the machine as a resolution to this. But to me it implies this specific issue isn't the typical needs a new logic board/GPU hardware failure. And sending this in isn't likely to fix it. Or at least I haven't yet seen evidence that it does. But I have seen enough people claim it hasn't that I'm moving towards the sleep/wake crashing being Catalina related.

That said, I haven't so far experienced any noticeable effects from having standby off. There is still a sleep/low power mechanism built in. I came back to 100% charge with the laptop closed for a few hours, and it woke up like normal. Standby supposedly doesn't even kick in until at least 3 hours in idle sleep - which makes this working for me even more confusing.

The amount of time you're going to be without the computer from the constant exchanges surely isn't worth it. I suppose replacing it with a newer model is an option. But that ended up costing you how much more in the end? Applecare+ and then the deductible.
