MBP 16" 2019 CRASHES WHILE SLEEPING

Yup, disabling Power nap worked for me too.

I've been having crashes for the past 2 months or so. Tried all other solutions (3 different calls with support and many hours diagnosing), but turning off power nap is the only thing that worked.

So to everyone who is new here with this problem, try this first, before you waste hours on re-installs etc.

Now let's hope Apple fixes this real quick.

Same model here, MBP 16" i9, 1TB SSD, 16GB RAM, 5500 4GB, Catalina 10.15.4 (19E287).

Brand new, same issue. I performed a clean install rather than backing up from time machine. Same story.

To me worked disabling power nap (in the plugged in tab - energy savings).

Looks to me that this is a software issue, but I'm still worried, just updated from a late 2012 mbp 13" which worked seamlessly.

3300€ for a pro machine shouldn't be like that.

Not really sure if give the machine back.

Actually yes, it has worked like 1/10 times the past months. I didn’t really care about that though, as the crashes are way more of a problem.

Btw, I have a fully maxed out machine, except for the 2tb ssd.

Hey, just now it crashed again. I just found it with the fans at max, hot enough to boil eggs on it. Then it shut off and restarted to the state, i would find it when in crashed during sleep.

Someone mentioned a supplementary Update? I don't have any updates in the sys-prefs nor the app-store. Do people still have this problem?

It started for me, after it installed the latest update 10.15.4. This is a software problem, which renders my 5k mbp unstable. I would really appreciate immediate support!

It's the same specs as the thread owner. Also use Bootcamp.

I'm curious why this thread has been marked 'Solved' as it's clearly not_solved and the reply tagged 'Solved' offers no solution at all. In fact, he/she states they are still having the problem in the post.

I solved the issue by replacing the macbook. Amazon hopefully provided another machine.

First one was manufactured mid october 2019, actual one that I'm using mid december 2019 and it's working flawlessly.

Same identical specs, same backup, same everything.

I'm curious about when the panicking macbook pros 16 are produced!

This is interesting.

I experienced the problem with Power Nap enabled and my MBP was produced in late October 2019. Maybe it's just a small range of MacBook Pro 16" models which are affected.

EDIT: Manufacture date was obtained by using coconutBattery, unsure as to the accuracy of the manufacturing dates reported on this software.

Just got my new 16" 2019 MacBook Pro a few days ago and experienced this "crashing while sleeping" phenomenon a few times now. Just downloaded CoconutBattery 3 and my laptop was manufactured 1/20/2020. So I'm not sure if the date matters here. I did do a fresh install after receiving the device because I wanted to set up multiple partitions. I was worried it was related to that, but guess it's not looking at how common this issue is.

Yeah, can guarantee it's not just your MacBook. As I said in a previous post:

Power nap seemed to be the issue. Got off the phone to AppleCare team last night and they confirmed to me that it is a known issue specific to 16 inch MBP’s and engineers are working on a fix

I've had exactly the same issue, all started after an OS update so hopefully it's a software issue that will be fixed in the future. Apple Support just told me that I needed to disable sleep for the SSD and this has so far solved the issue.

I have the same issue on the my Mac book pro 16. During the first two months it wasn’t quite often - maybe 1 crash in a few days, maybe once a week, but now it happens 1 or 2 times a day. I took my Mac to the service center and they made hardware tests and ensured me that problem was with the software. They did reinstall the software and told me to drop power or nvram to solve the problem. Most often Mac crashes when exiting the sleep mode with by the mouse move, or on any keyboard event, but now it’s been lagging , and then crashing while I’m working. The Mac support advised me to reinstall OS but it didn’t help.

10.15.5 Here, I'm having the same issue with my MacBook 16 2019, just bought it couple days ago, I'm using it in clamshell mode and it crashed every time when I try to wake up the computer. Extremely unhappy about this, if this isn't fixed soon, I'll just return it
