M1 Mac mini display issue

Snow picture still appear on M1 Mac mini with Big Sur 11.3.

I don't see pink squares now. Earlier they appeared after every restart/reboot of Mac mini.

I finally solved the problem with black screen after updating to Big Sur 11.3. It simply does NOT wake up on clicking external USB mouse / or keyboard. I unplugged USB cable and connected again. Now I could wake up M1 Mac mini.

More problems. When I tried to replace a monitor, Mac mini didn't recognize a new monitor with HDMI connection. I tried a half of hour to get it work. Then suddenly it started to work again.

So it's really TERRIBLE! Too many bugs and problems. I regret about buying M1 Mac mini.

These pink squares really doesn’t bother me at all. It appears sometimes on the login screen.

It doesn’t effect the performance of the Mac.

I’m using the Mac mini’s HDMI port for my main display and for 2nd monitor I’m using my thunderbolt 3 docking station’s display port without any issue.

I had problem with waking up the 2nd monitor at the but after first update the problem has gone. And after the last update the pink squares didn’t appear yet. Finger cross!!

The latest update on the device and I have not seen a pink square since. However, twice now the device will not wake (or wake monitor) after sleeping. I read in the myriad of comments here that perhaps I should try disconnecting my monitor and then reconnecting (or turning off and on) after such an event. I'll try, but there is still something wrong with the software/firmware (???). How sad that Mac is so slow to respond.

Exactly the same problem here. Tired different HDMI cable, DVI cable and monitors and it’s still present. Not much else to blame.

Same issue for me pink squares. After logging in, visible for a few seconds, then disappear. Guess it's a software issue, but no fix or Apple reply soon and I may return it. M1 16GB 1TB

Internet. It automatically downloads the most current version of Big Sur.

Yes it happens to me too only when booting and every gets fine once booted.

After replacing my HDMI cable, I've not encountered any issues at all :)

Omg. Just return the machine. That speaks louder than these forums.

dtsardakas , I don't think it's a hardware issue I had it with my 2018 i5 mini too, though less often. We just need to wait out a software fix.

I have the update 11.1 and only turn off the filevault, the restart is faster and without problems on both monitors

Did you try 10 or more restart to your Mac mini? Are you so sure that your issue “pink squares” is over?

I have same issue with small pink cube

and today also this “snow” screen. After rest it’s disappear.

I think when the Mac mini cold it’s do the issue

pink square still not resolved in 11.2

I tried 11.2 Beta, 11.2 since yesterday I still have pink squares at startup, with sharing display I don't have a pink square even when they are on the main monitor.
