MacOS Big Sur freezes, pink screen and restart

I bought my MBA M1 two weeks ago direct from Apple and it was delivered direct to me because the memory and storage config i wanted wasn't available instore. I am in rural area and won't be near any computer store for another month. Pink screen/restart happened yesterday one hour into working with a simple Word document, and same today. i sent the automatic report to Apple. I'm using ALL new equipment - apple brand USB-C to Digital AV adapter, hp monitor, logi wireless keyboard and logi mouse. I only hooked up the external monitor, and connected the mouse and keyboard one day ago. Maybe one or more of the accessories is incompatible? I have Big Sur 11.5.1. Added note: I have sent the feedback as recommended by Doctor Zhivago.

I've also got the same problem just a minutes ago my MacBook Air M1...all of the sudden the screen freeze and there's a pink lines I tried to pick my phone to take a photo but the MacBook just reset it self..

I think I've been opening up too many pages and tabs might cause the problems / also I haven't shut off for many days only on sleep mode

I figured out what I'm doing that is causing my crashes. To give credit where credit is due, one of my sons suggested this as a remote possibility, and I merely tested it out...

By trial and error I discovered my pink-screen crashes are ALL about sequence of connecting things up:

(a) it never happens when my computer is not connected to the monitor;

(b) it never happens when I awaken my MBA, and then connect the sleeping monitor to my MBA (via Apple adapter);

(c) it always happens, in less than an hour, if I connect the sleeping monitor to the MBA (via adaptor) and then awaken my sleeping MBA.

This has now been reported to Apple engineering department, along with the lengthy error message the computer generated when it crashed.

My monitor is HP f2 24-inch (23.8 inch). To run, it must be plugged into the wall. I keep it plugged in and I never turn it off, just let it sleep. Similarly, I do not turn off my MBA; I just close it and let it sleep.

Hope this may be of help to at least some of the folks out there.

I think every contribution on here is useful is some way, especially if it gets reported to Apple (which doesn't happen via these forums). However, your experience doesn't explain why my 1 month old MacBook Air M1 exhibited the same crash symptoms, yet has never been connected to an external monitor and wasn't connected to anything at all when it happened. It has never happened since - so I have to assume (in the absence of a credible explanation) that either Apple has fixed this in a subsequent update (hard to tell as I don't know how old some of these other examples are), or that one has to put it down to a strange one-off glitch.

To be clear, my MBA was brand new three weeks ago. I upgraded to Big Sur 11.5.1 within days. A few days after that, I connected my brand new monitor as mentioned (with a brand new Apple adaptor), and that's when the crashes began for me.

Also, the last time it happened, the restart failed so I had to manually reboot.

I just had EXACTLY the same thing when my 13" M1 MacBook Pro (8GB RAM) crashed and restarted (with a black screen with jagged pink lines). I read your post while researching the problem, then checked my storage and I've got literally 20GB more storage now (hope I've not lost anything important!). So weird....

Strange you should mention the remaining memory increase - irrespective of the pink screen phenomenon, I find I frequently have slightly odd patterns in the change of available memory on my MacBook M1. A restart always seems to give me 3gb - 6gb extra!

FWIW I had my M1 MBP plugged into mains via USB-C (the standard Apple mains adaptor) when I experienced the crash problem. I don't tend to use the laptop while it's charging, the battery lasts so well I can usually use it all day and just leave it charging overnight or when I don't need to use it, but when I had the pink screen crash it was one of the rare times I had it plugged into mains (and if I recall correctly I might have just adjusted the angle of the screen when the crash immediately happened). Super weird!

So far it has only crashed when i connected to the monitor BEFORE waking up the MBA. It has never happened when not connected to monitor, and it doesn't happen if I wake up the MBA BEFORE connecting the monitor via Apple adaptor. I need thr monitor a lot for my work, but not always.

One week old iMac 24 - I can’t even get it to run anything - it’s crashing every 5 minutes. Apple have agreed to replace it but am waiting 4 weeks !! Have sent feedback via the links - my first time using an iMac and I’m not impressed at all.

i have the same problem, macbook pro 16 ram chip M1. When I perform tasks with a large load, it gives an error and a pink screen.

Maybe crash report will help to identify the issue?

Worth reporting via Apple feedback, they don't read these user forums - but they do read direct feedback messages:

My Mac Pro M1 (8 gb ram) get this screen when it freezes (that happen some times but not so often). The
