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 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.

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.

Same exact problem here, and I also get crashes while running gpu-intensive apps (Unity 3D). I took it to the Apple store, they ran all diagnostics and everything came back fine, they recommended wiping and reinstalling, I said no thanks and returned it. Am waiting a few weeks before I decide whether to replace or not.

There's another thread over about this or similar crashes on the new 16" Macbook Pro: https://discussions.apple.com/thread/250905859

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

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

No one, company or individual, can debug a machine with dozens of add-ons. It needs to be standard all-Apple. The requirements is not "blow away your drive" it is run in an unmodified MacOS.

MacOS can boot from any drive, Internal or external, after you make some adjustment is the T2 chip. You don't have to erase your drive, just use an external drive and install a fresh, unmodified copy on the external drive.

Nope. It did it again. Sorry for wrong alarm.

As a temporary workaround, I turned off "Automatic graphics switching" off for Power Adapter in Energy Saver settings. This seems to work for now. Will update if it happens again.

I've read in other forums related to the Macbook Pro 2019 16" model freezing with black screen/restarting to try running it in safe mode.

The reason being that running the system in safe mode and experiencing a freeze/restart around a gpu switch or sleep is said to determine a hardware fault as opposed to a Catalina fault, this applies only to the Macbook Pro 2019 16".

Got a huge project due tomorrow but am spending the night erasing my original macbook pro 2019 16" (but with 4 logicboard replacements, lol) and moving data over to my older slower iMac.

Amount of time lost to this situation is so ridiculous now, and it all boils down to apple's poor company policy blaming users for faulty products out the box.

So courier pickup tomorrow, 1 week for apple to get it. Then a 3-4 week wait for a full replacement, counting the logicboards that's number 5. NUMBER 5.

Something is seriously wrong with apple. These new 2019 macbook pros are too much of a risk, I was meant to be editing videos on the move with it and it provide ample computing power away from my desk while travelling.

But Nov '19 - Mar '20 it's been 10 hours of driving back and forth, almost 12 hours on phone to apple support, multiple logicboard replacements, now a full replacement because I pointed out battery hasn't been able to do a full 0% - 100% cycle since purchase due to constant freezing and restarting.

This machine is not ready for business but sold to professionals purchasing for business use. Quite the joke. If this 5th replacement is faulty guess I'm doing a return and put myself behind 4 months in my work just to try and get a macbook pro 2019 16" from apple that doesn't freeze.

I've also paid for apple care "+" but basically just paid for the honor to be blamed by apple for 4 months. If this is the start to this macbook's run then it won't see the year out. I wouldn't work on it for free and it cost me $7000 for a build-to-order spec.

Steps to reproduce. Can anyone try it out?

1. With power plugged in, start a youtube video playing in fullscreen in chrome. (Something to make sure the graphics card is being used.)
2. Stop the video but leave it open.
3. Close the Macbook lid (power still plugged in)
4. Unplug the power.
5. Wait 10 minutes. Set a timer. Really. A full 10 minutes.
6. Lift the lid to wake back up the mac.

Result: The screen is black. After several seconds the fan spins loudly and stops. The Mac reboots with this crash.

Thoughts:

Figure it’s a hardware failure with the graphics switching. Just started a few days ago after everything being fine for months since I purchased the Mac.

I prefer to use Onyx for a thorough clean, CleanMyMac is used for quick cleans without typing a bunch of stuff in terminal.

All of my software on macOS has been chopped/changed since I started using it in 2010 to the most compatible software for my macOS based workflows. All my software on macOS is 64bit and I began that transition when I was on High Sierra.

When hundreds of software applications made specifically for macOS stop working, I doubt the problem lies with hundreds as opposed to one, macOS.

TLDR; no, CleanMyMac isn't the problem here, and it cops some heat being one of the first pieces of software users with no idea how to run and maintain a system go to, and thus gets caught in the crossfire of an already badly configured system and unarticulate user.

clean installation via the Internet with disk cleaning. Problem still exists. It is very clearly visible when you turn off the integrated video and it immediately freezes. When loading, here is such a picture.

The panic mentions an issue with the GPU, but this could also be caused by third party software. Run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper.

Same issue here, saying there's a GPU kernel panic.

Just got my MacBook Pro 16 less than a week ago and it came out of nowhere.

Whenever I put my laptop to sleep or close the lid, it crashes and will keep crashing until I do a hard shut down.

I am having the same issue, the laptop is 10 days old. It seems there is an issue with some motherboards of the 16in laptops.

A colleague is having the same problem. He is already awaiting for 3 weeks; no answer from Apple, when to expect the new motherboard.

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.
