Macbook pro 16 2019 freezes randomly and restarts

Apple have always been in denial about issues with their products until ages later and huge public pressure.

Under pressure to have a mobile 4K video editing solution, and knowing the keyboard was awful, but willing to suffer the low travel keys, I bought a fully loaded 15" i9 MB Pro in May 2019 for £4000. Yeh, four grand, as we say in the U of K. What I didn't expect was to constantly hit the Esc key (and rest of touch bar) by accident, causing chaos - I have been touch typing since 1980s and type properly. Worse, and the key issue, the machine would slow down under load, throttle, so a pain. They then scrapped it (a first for Apple) and launched the 16", that whilst retaining the central touch bar, did improve the other issues. (I am typing this on one now.) So I politely asked Apple to swap my troubled 15 for a 16 or refund me. Made a very good case. Their staff at the store were rude and in denial, saying "Sell it online and buy a 16". I was dumbfounded. I gave up, flogged it in eBay for about £1600 and bought this £4200 16 inch because I need it to produce videos. Will seek compensation later. Apple have never done this before, the old AirPods are still for sale (pre Pros) as are Apple Watches prior to the Series 5 and some other even older products. By withdrawing the 2018/19 15 Inch MacBook Pro, Apple were admitting it was a flawed design.

I have an appointment @ Apple this week, but because I bought this on Amazon I was told by support they won't exchange it! I then spoke to Amazon this morning and they will replace or refund without question (only have had this for a week) BUT, they also offered me €450 compensation if I just keep it! I almost fell off my stool when the Amazon representative made that suggestion. I even received an email confirming there offer that is good for 2 weeks, so I have time to debate if I just live with the problem. Right now I have no sudden restarts, it's just when waking up and even documents I haven't saved prior to the "wake up crash" are saved (I've tested this several times)! What a dilemma! I can save a hunk of change with just living with this mess or start the exchange process that will only function over Amazon! At least Amazon is fair about the situation & not like Apple that refuses to do ANYTHING!!!!

I have this issue too. 16" i9, 2.3Ghz, 32GB, 1TB SSD, 4GB Vram.

I experienced the random lockup once or twice during the 12 hrs of usage. the random lockup occurs after 2 week of the device with me. Just like the others, occurs when using Chrome.

I used to have the random restart too. but the SMC reset fixed it somehow.

I hope this is a software issue and not a hardware one. I have the apple care + so if this tends to be a hardware issue I know im covered.

By the way, i didn't experience this kind of issues on my 2015 Macbook 13". What's happening Apple?!

It's random but I seem to have suffered the freezing when macbook went to sleep under intense load, & plugged in to power.

So perhaps set power options to sleep after a minute, and leave some video rendering.

My experience has been to walk away from a video rendering, come back to a macbook I thought was sleeping, only to be logging in after a restart and everything is closed.

This is interesting. Both my prev 2019 15 Inch MB Pro and our new 16 crash when asleep. On waking or restarting I get the message stating there was a shut down problem and an option to send crash report to Apple, re open apps etc.

Does your MacBook have problems when going into the “sleep” mode? Or actually it would be waking up again? You would receive an error message that gives you the opportunity to “ignore” or “send” (to Apple). Here an example of the message you’ll see when you hit send and if you have this then you’ve got the same issue:

I was hoping this new update that came out today (10.15.3) will solve this problem for me, but sadly it does not... Looks like I will have to go get a new replacement.. :(

MBP16' 2.6 6 Core i7 16gb 500gb

Intel UHD Graphics 630 1536 MB

The new update came out today! Hmmmm, I’ll try it out but I already fixed the problem when connected to power by doing the SMC resets & changing the power settings:

System Preferences > Energy Saver

And uncheck the Automatic graphics switching."

It only gives me these messages now when it sleeps under battery use! I canceled my Apple appointment because they will just want to reimage anyways & I already tried that with NO SUCCESS!!! I’ll just live with the mess...

Something that I didn't mentioned in my previous post is that in addition to disabling the Automatic Graphic Switch I also have my Touch Bar configured as Expanded Strip, showing the old function keys statically instead of showing dynamic content (App Controls).

I decided to share this because few days ago I decided to switch back to the default Touch Bar configuration with App Controls that change depending on the app or activity that you are doing and few hours after enabling it my laptop fans went crazy and the whole system got unresponsive so I had to reboot it using the power button, as soon as it booted again I changed my Touch Bar config back to Expanded Strip and everything is working again.

So if I have Automatic Graphic Switching turned on or my Touch Bar set to App Controls my system is almost un usable having to manually reboot at least 2 or 3 times per days.

Another thing that I noticed while testing with Automatic Graphic Switch turned on today is when the Intel graphic card is in use even basic system are bit laggy, like switching between spaces or get in / out of full screen, everything works great when the AMD 5500M 8GB is in use (I left the automatic graphic switch turned off)

I am running the latest OS version 10.15.3 (19D76).

Spent $5k on mine and it's crashing at least once an hour. Reset the PRAM and SMC, ran DiskUtil, and it still can't stay up. It even crashes with the lid closed.

Apple has to address this. The machine is barely useable.

I sent mine back!!! As of Friday it didn’t start in normal mode any longer! For some reason it ran for 2 days prior to this issue without problems, and then one time “lid close” and that was all she wrote! Spent hours trying to fix it using all the tricks in the book (again) to include complete re-image, to no avail!!! What a piece of crap!!!! And of course Apple support (called 2x with about 2 hours waiting time) couldn’t help what so ever & seemed to not even know the problem exists! When I asked if they ever look at the Apple help forums they said “this is not an official website recognized by Appel” although this is on their website as link! In summary, send it back if you still can, drink a big Jackie & try to forget you wanted so many brain cells on something that, according to Apple, doesn’t exist...

I can confirm that the 10.15.3 update DOES NOT fix this problem. As an additional "feature", the crash now bricks my machine for 5-10 minutes. It's also crashed so many times during backups that my Time Machine disk is hosed and will probably need to be reformatted. Still trying to save data from it.

It's either the mainboard or processor! Nobody from Apple will be able to help you because it's simply a HW error that they don't even acknowledge exists! As I stated before, I sent my MacBook Pro "16 back after 2 weeks of nothing but problems & purchased a MacBook Air! Couldn't be happier with this decision because I haven't had 1 error since I've owned it (24 hours). Did some homework prior to this purchase & nobody complained about Kernel Panics, standby problems, etc.

Buying a MacBook Pro is like playing the lottery = maybe they function without a problem or they crash multiple time per day. You'll never get rid of this problem sir if it exists & sooner or later you won't even be able to use the thing unless it's started in "safe mode" only, even if you wait a 1,000 Apple updates!

Good luck!

With the GPU switching disabled, I managed to make it over a month but half an hour ago, my 16" panicked with a BAD MAGIC message on reboot. I did not get the option to send the report to Apple which I found odd. No video running, just a few browser windows open. This time, the fan did not spin up as if the unit was overheating, but it might have been at the very beginning of the cycle since it made sort of a "ping" sound as the screens went blank. Am still on 10.15.2. I strongly recommend returning any unit that is within the return window and walking away because it is not worth the aggravation, especially for a $3000 notebook. I would also recommend avoiding new purchases of the 16" altogether especially as an upgrade from a 15" since loss of work is costly and Apple's costly, ineffective Applecare coverage provides no solution other than to reload the operating system and wait until it crashes again. Once you are past the return window, you are stuck.

I’m so happy I got Ris of mine before the return window expires! Bought a MacBook Air 13” like I had for years before & NO PROBLEMS WHAT SO EVER! The MacBook Pro is the worst computer I have ever had! As someone had mentioned in all the forums I looked at trying to somehow fix the problem “it’s like having a computer from the mid 90’s”! Good luck to anybody that has one, but it if you believe the problems will disappear magically using one of the suggestions in this forum, FORGET IT!!!! Thanks Apple for making my life miserable for the couple of weeks I owned that piece of CRAP!!!!!!!!!
