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.

This app is good for spotting bad kexts and removing them:

Currently spending my evening formatting my replacement mbp 2019 16" for what feels like well over 100 times since Novemeber 2019 with these machines. 5 months now without a fix or even a hint from Apple as to what is making this one of the most unstable macbooks ever.

Yeah kextviewer is an easy way to see that those were apple kexts.

As someone that's had apple go through multiple mbp pro 2019 16" machines (requesting a format before), look at crash logs in a fresh install and determine something is wrong then issuing replacements, this situation is highly frustrating.

I think it would be best if owners of the mbp 2019 16" only commented. Nothing worse than buying a super expensive machine for it to freeze & restart. My latest replacement did that out the box with nothing installed and has continued to do so. I formatted again in preparation for my next call from apple but in reality phone support can't help and my next step will be to drop it off to the repair center again.

Like when I said 5 months without a fix apple have replaced my logicboard multiple times, and even issued me a full replacement. Stuck in a loop of no refund. I think the only correct thing I read in above statement was consumer protection laws, which in my country need to be backed by a court case. Last time I went to court was never so thanks for the advice and thanks apple.

I can't say for sure, but a clean install of 10.15.4 on my latest mbp 2019 16" seems to have done the trick...I've only been using it for a day though, lol.

When my replacement unit first arrived, it came with 10.15.3 preloaded with a freeze & restart without installing anything, then I installed 10.15.4 over the top. It was still freezing & restarting.

Then I formatted the macbook with command + R at boot, when in internet recovery I first went in to Disk Utility and erased the internal nvme by right clicking on each container and selecting "delete APFS container" for both partitions. Then I erased the disk to be sure. After that, I then installed 10.15.4 fresh.

Since doing that, I have been using the macbook heavily with most of my software installed but no crash.

It's a pain to have to constantly format for something that may have been fixed in 10.15.4 with previous 10.15.x versions of Catalina not running in a stable manner on the system, but give it a try. What amplifies the situation is apple's total lack of recognition on the issue, you are stuck proving to them it crashes and then their only recourse of action is to replace your system or logicboard.

This issue could be better addressed, especially since at this current point of time this is apple's 'best macbook' and users are left spending countless hours on the phone and driving to stores/repair centers for what may have been something addressed in 10.15.4 with a totally clean install.

Macbook Pro 2019 16" crash on sleep and force restart related to GPU Panic.

I still see it today same GPU panic crash every single time I open lid. Apple should address and send a software update to fix for all machines affected by this bug!

If anyone gets a response from Apple please post it here. Thanks.

Quick update... Apple support got back to me. Engineering said they needed me to try one more thing on a newly installed MacOS with no 3rd party installs. They wanted me to turn off my Sonos as the streaming wireless may be affecting the computer.

That was my last straw. I told the support to pound sand on that as a Sonos broadcasting on its OWN network (I use a SONOS bridge) will have no impact. I explained that if it did, then they have a serious security issue on thier hands. Imagine crashing GPUs because there is a SONOS on the network somewhere.

He ultimately agree with me and told me he would tell engineering to pound sand. He was in agreement that it was very likely hardware related. He is awaiting a final from engineering.

At this point if i don't hear back from him in 48 hours, I will initiate a chargeback on my credit card and force a refund on them.

Hard to believe since its only 2 months old and I bought Apple Care. They should be handling this a bit more expeditiously.

I'll update when I hear back.

... if I close the lid and open it up in a couple of hours (I assume after the MacBook has gone from sleep to hibernation) it always does a cold boot. After I insert the password, I get a black screen and all the fans got 100% for one second. Then it boots again, I insert the password and I get logged in. I always get a crash report from the OS.

Exactly same issue as mentioned here.

Hardware: MacBook Pro (16-inch, 2019)

It happens several times within 12 hours starting from about 12 hours ago. I have installed nothing within this period of time.

Most of the time, I just use this computer to code and view webpages. I have reset the SMC, but it seems useless.

I have the issue with Radeon Pro 5500M on MBP 16 inch. I tried all solutions (reset everything and reinstall them) and nothing worked.

I brought the computer to Genius Bar several days ago, they ran a basic test and there is no hardware damage. Therefore, they just replaced the logic board for me. I have not get back my computer yet, once I get back the machine, I will test and feedback here.

UPDATE. Problem Solved !

About my problem. I tried disconnecting all the devices. When all devices were disconnected the problem didn't happened any more. So I started connecting one by one, testing which one was the problem. I found the a Power Adapter from Magsafe 2 to USB-C was the problem. I stopped using it and the problem didn't came back.

I strongly recommend to test your devices to identify if that is the problem.

Best Regards to everyone and a I hope my experience can be helpful for someone else.

I suspect it's heat related.

Interestingly, plugging everything into the wrong side of the Mac (the left side) can apparently increase heat issues. I now ONLY plug my power in on the right side.

I know it sounds silly, but see this article.

Also, be warned that privacy webcam covers CAN CRACK YOUR SCREEN. Even thin ones. This happened to me.

They replaced the logic board, and the T2 Chip. I haven’t had any issues since. The key is to tell them that you have already gone through all of the recommended troubleshooting steps including reinstalling the OS.
