M1 Mac mini display issue

Much as the (mainly) U.S. glossy format for YouTube reviews works to gain clicks/views, it feels disingenuous that more of the issues aren’t being highlighted so people can make an informed buying decision.

One of the channels I watch has been doing a lot of tests and have noted the pink squares, slower WiFi and slower USB speeds than the Intel chipset. They said they’ve tested but couldn’t find any Bluetooth problems that lots of others have reported, but at least they are honest about the teething problems.

I quite like the glossy format of some of the channels, but they feel like advertising for Apple. Here’s something that blew my mind, here’s the biggest thing no-one is telling you about M1, here’s my top 10 reasons to do x,y,z, here’s why I was wrong about Apple, blah, blah, blah...give me a couple of geeks giving me some actual info any day.

Yup exactly the same on the i5 which I sold to get the m1 mini. Makes me highly suspect software and some googling has shown that there were similar issues that were even worse with pink square stuff on other models of macs that were fixed by software updates.

Just to raise the confusion.... :) On a non real mac running big sur the pink squares arent there :) Under Beta 2 the situation is better, the pink squares immediately disappear after launching firefox :)

UPDATE : It didn't fix the issue :(

''i read from the macrumors forum that disabling the “display spaces” from the mission control in system preferences might fix the pink squares error. Did someone try that ?''

List of my failed attempts dedicated to the next victims :

- tried the m1 on 3 different monitors via hdmi and hdmiTOusbc hub

- tried 3 hdmi cables that i constantly use for multi cam live streaming 

- bought 3 new hdmi cables (1 belkin, 1 Philips, 1 hp) and tried the m1

- erased and reinstalled the OS (using a 2nd mac running apple configurator 2)

- updated the m1 to big sur beta 11.2 (all updates done)

- disabled the screen spaces from the mission control

- tried the dark and light modes

- night shift is off so it’s not the reason for it

- called apple global and apple Turkey support for a fix

- disabled ‘wallpaper tinting in windows’

They've just released 11.2 Release Candidate which has "External displays may show a black screen when connected to a Mac mini (M1, 2020) using an HDMI to DVI converter" in the release notes as an issue that it addresses - no mention of the pink squares bug but might be worth anyone who's testing 11.2 trying it, in case it's linked. The pink squares problem has affected me using USB-C to DisplayPort as well as HDMI to DVI cables though so may well be a separate problem...

Hey everyone, I just bought my M1 Mac Mini today (8GB/256GB) and got a minor display issue after restarting it for the first time. Basically a series of small pixels across the lower portion of the background dropped out, our would shift when I opened menus and moused over apps icons in the dock. Prior to the first restart the only thing I did was install Adobe CC, Photoshop & Illustrator. I was able to "erase" the pixels that dropped out by opening Safari and just moving the window over the dropped pixel areas - like erasing them with the window. Almost as if they only affect the background, but nothing in the foreground. Very strange. I'm using an HDMI cable. Hopefully it won't happen again or often and Apple can work on a solution to this. Will update after some time if it persists.

Version 11.2 (20D53) solved the pink squares on my Mac Mini M1 also the secondary display sleep/wake issue.

Primary monitor is connected with HDMI, secondary is connected via USB-C to USB 3.0 + HDMI hub.

I'm just using an hdmi to usb-c cable (not a hub) and have had no more problems with pink squares, but when I change to hdmi to hdmi they return briefly on first boot only. As I don't have a secondary display I can't comment on that!

I'm glad I returned mine when I could. I'm starting to wonder if it isn't a hardware issue with as long as they're taking to fix it. Other software issues were fixed in short order and will be released in 11.2.

My Mac Mini M1 512GB 16GB displays these pink boxes at the login screen and for another half minute or so on the Desktop. They do disappear eventually. I am connected via HDMI. I even tried two new cables from Amazon; it didn’t help my issue. The boxes have never appeared during use of the computer. They only appear usually from a cold boot. I love Mac OS and the Mini. I hope they can fix this. I saved up for a few years to buy this computer, and this is so disappointing.

Wouldn’t turning FileVault off be dangerous though?

Can it he switched back on when the problem is solved?

If this is the cause I hope Apple are reading this, because it would push them into the right direction.

I returned my m1 Mac mini (16 gigs and 1 TBssd) few minutes ago and I'm not going to buy another m1 until all of the defects are announced to be fixed by Apple officially.

Btw. I am truly disappointed about the time I wasted with the M1 Mac mini trouble shooting and apple support communication about the pink pixels error.

I wouldn't bother turning off file vault if you have it on. Mine has never been on and I still have the issue, most likely the person suggesting this happened to by luck have a few times when the issue didn't happen and made up in their mind that this is the solution when it isn't. Given enough reboots they will run into the issue again until apple fixes it. Again suggesting people file bug reports to apple and just wait for them to fix it. Google how to bug report to apple if you don't know how.

Im using the latest Big Sur currently version 11.2 (20D62).

Have two monitors connected:

LG UltraWide 34UC79G-B connected with this cable:

LG IPS235 connected to the Mini HDMI out

No pink squares after bootup which I also had before from day 1.

The whole system is a lot snappier than before, Safari doesnt freeze when scrolling like in the previous buids.

I dont think you should return your Mini because you think this is a hardware fault, because it isn't... It was clearly a software bug. So my advice is to everybody... wait for the official release of Big Sur 11.2 and when it is out do the upgrade, it should solve the pink squares problem after bootup. Im not working for Apple :)
