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.

News from my MBP: It's still in repair and the repair shop confirms a hardware failure. System crash (black screen, fans blow up, reboot immediately) when switch to 5500M GPU, probably this switch doesn't occure in safe-mode. The system crash even in Apple advance diagnostic program (from a netboot image), the built-in diagnostic (press D on boot) doesn't report any error.

Result: A new logic board from apple is on the way and I should get back my MBP next week.

(MBP 16inch, 2.3i9, 64G Ram, 2TB SSD, GPU 5500M 8GB)

This is not software. After 3 weeks of working with an Apple customer service rep and doing everything under the sun, we finally had it shipped to Apple. They fixed it in a day and are currently shipping it back. It is definitely a hardware problem as confirmed by my support engineer and Apple knows about it very well.

THIS IS NOT SOFTWARE AND IT WONT BE FIXED BY A SOFTWARE UPDATE. <---- READ

If you have the GPU panic problem, contact Apple as you have a warranty and have them fix it. Don't wait, because if your warranty runs out and you don't have Applecare, then its on you.

As soon as I get the detailed problem and official hardware fix, I will report back. But at this stage, this is a confirmed hardware problem and can be fixed only by Apple.

I am having the same error.

I got my 16" MacBook Pro a week ago and it worked fine for one day when it was connected to a charger. But 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.

Back when I had 10.5.1 it was a kernel panic and said something about the CPU related setPowerState() function failing. I saved all these reports into files, but then one day the MacBook went into an endless boot loop and I had to reinstall the OS. That's when I lost 8 of these reports that I had stored on the disk.

Now with 10.5.2 I've only been getting GPU panic reports. Most of them have said "PowerPlay Failed Resume" and I was surprised that I found zero Google results with that exact text. Today I got my first "PowerPlay Failed to Initialize" and was able to find this forum thread with it.

I will be sending this unit back to Apple as I believe it to be a hardware issue. I've had problems with 10.5.1 and 10.5.2. I did a clean install of 10.5.2 and got the crash report even right after finishing the setup. I believe it's either in the CPU, GPU or the logic board.

I'll write here when I hear what they did to the MacBook in repairs.

P.S. During writing this post the MacBook did a sudden cold reboot while it was just on idle on the desk next to me. When I got to the desktop I got another "PowerPlay Failed Resume" but the system was also very unresponsive. I was unable to copy the full report to TextEdit or even press the "Send" button on the report. Mouse stopped moving. A minute later a black screen, 1 second of 100% fan noise and another cold reboot.

I was having the same issue with my 3 weeks old MBP 16in, went to the apple store and ended up having to return it and order a new one. Originally they wanted me to pay for the repair but they ended up extending my return period because it seems to be an issue with some of the models. Hope this helps some of you with the same issue, don't waste your time trying to troubleshoot it yourself.

Feedback here: I got my MacBook Pro back for 2 days, the Apple changed the entire logic board and the Touch ID module. Everything works fine now.

Hardware: MacBook Pro (16-inch, 2019) with AMD 5500M

Guy from Genius Bar recommended me not recover the data from Time Machine because some "bad settings" might lead to this problem, but I recovered all the files and nothing bad happened. So I suppose this is just a hardware issue, any reset might not help.

Maybe apple should check the design of logic board, because this seems not to be a individual problem. I know 3 or 4 guys in China having the same problem.

For anyone having their Mac for 2 weeks or less, I would print my receipt and take the MBP back to a brick and mortar Apple store. Apple will take it back unless it obviously is damaged.

I spent 3+ hours on the phone with Apple Support. They logged into my machine. I had already rebooted and wiped my drive. They looked around for a while but in the end concluded it was hardware. I returned since I was within my return window and got a new one. I've read that it is either the T2 chip or the GPU. I had the higher end base model with the 5500M 4GB but I'm not sure that matters. So far my new one (slightly upgraded) is ok but every time I boot I cross my fingers.

I've got my 16inch back from Apple Service Provider - there was an error on logicboard, the MBP crashes everytime in switch to dedicated GPU. With the new logicboard it run's fine since last friday - finger crossed.

from the extensions listed, you appear to have added some additional AMDRadeon drivers (I have never seen these listed first, that is the position for non-Apple extensions).

loaded kexts:

@kext.AMDRadeonX6000 3.0.8

@kext.AMDRadeonServiceManager 3.0.8

>!AGraphicsDevicePolicy 5.1.16

You will need to remove those and reproduce the issue without them before contacting Apple at 1-800-APL-CARE or using the Contact Support link at the top of every forum page.

Use the Contact Support link at the top of every forum page. If they agree, you may be able to arrange for a courier to pick ip up and send it to a repair depot.

If its is more than 14 days, this falls into the Repair category. Apple promises to repair or replace at Apple's discretion, components found defective in materials or workmanship during the warranty period.

They don't generally send you a completely new computer. That said, if they replace the mainboard, it includes the processor, RAM , both graphics processors and the Boot Drive. So you essentially get a new computer out of it.

Got my MacBook Pro back from repairs about a week ago. Logic board was changed. Haven't had any crashings since.

My GPU is the 5500M 4GB

Service center confirmed - my mac needs motherboard replacement.

Had a call with Apple customer service and they concluded it must be a hardware problem, so I sent it in for repairs yesterday. No estimates as to when it might come back.

Luckily I just replaced the battery on my 2013 MacBook Pro that had a swollen battery. This thing is rock solid. Seems like during the 6 years it hasn't gotten any slower. This unit will probably keep on going when the 16" comes to it's end of life.

In fact Apple Engineering wanted Dropbox removed... yes Dropbox strangely enough.

That is standard procedure when troubleshooting the source of a Kernel Panic (or any issue actually) in order to determine if the Kernel Panic is caused by hardware or software. Uninstalling all third party drivers/extensions or even better yet performing a clean install of macOS (erasing the whole drive and reinstalling macOS without migrating or restoring apps/user folders) is the only way to separate out a hardware issue from a software issue. Just because DropBox is a common app does not mean there couldn't be a bug in the DropBox software which is interacting badly with a driver specific to this particular MBP.

I do realize the MBP 16" GPU Panic is most likely caused by a macOS driver bug or faulty hardware or firmware.

Did anyone experience MacBook shutting down at the initial login screen, if not logging in, just waiting a few minutes?

The fans start accelerating, slowly becoming louder, and then after a few minutes, the laptop shuts down.

My previous 16" did the same thing at the beginning. Later it started crashing, following the 1-sec fans blaring. After that, I couldn't log in at all; the same story, login stops at 65%, restarting over and over again.

Apple confirmed its a logic board issue, and they sent me a new 16". However, I'm concerned I will have to send back the second 16" as well.
