M1 Mac mini display issue

yesterday I went to the apple store and they saw this issue but they send me to the place where I bought this Mac mini. 🤬🤬🤬the most worst experience of apple devise in my life also apple support same as my experience. It’s not a display compatibility it’s a HW issue for sure because at apple store they said need change it in the place where I bought or fix it at any apple store but this device is new so need time from 7 days to 14. I activated it 6 of December. Used it with pain and issues until yesterday and they can’t change it at original apple store I’m really disappointed and of course don’t wanna wait so long because they need to test it. They need check this thread and start to react not just keep silent . First time I went in Genius Bar they found problem and seen it but don’t want to change it. It’s disgusting

If you want to return or replace it of course you need to go back to where you bought it. Of course. It wasn’t sold out of apples stock. They sold it to the retailer. Did you get apple care on it? If not yes your only viable recourse is to return it to your retailer. This isn’t evil of them. It’s just standard product channel management.

I found something strange , if you Disconnect hdmi and then reconnect it the squares go . Almost like it is a HDCP error at startup :/ If so this could be linked to the hdcp errors with some hdmi and display controllers at the moment used in many electronics including some macs. If that is the case then a firmware fix may be possible :)

So, I updated to 11.1 and those little pink buggers came back on a cold boot today. They lasted about two minutes and then disappeared. I also got my Magic Mouse 2 today and I am already experiencing bluetooth disconnects. My Magic Keyboard works well. Why did I switch away from Windows 10 again?

Sad thing is that, I just posted my Windows laptop on E-Bay. I still have the option of returning this mini and getting something else until January 14th. We will see if Apple response with a good solution by then, or this thing tanks on me.

I have the same problem. It happened after my display ended up splitting with a line about 4/5 to the right side. The screen would shakes and it's like the 1/5 of the right side of the monitor became what should have been the 1/5 of the left side as I would drag my mouse left and it showed up on the right. This issue has happened to me at least 4 separate times usually after the computer hasn't been logged in for a while. Today after rebooting it showed these pink squares exactly as you described and they went away quite quickly. I have seen the pink squares before.

I also cannot use the display over the HDMI port it only works via USB C to HDMI adapter. The Mac recognizes the display through the standard built in HDMI and the resolution is set correctly, however there is no signal and my display advises me the frequency is incorrect. This display works on my 2012 Mini and several other devices as well.

"Yep, it's PC and Windows for me once more. The so called 'Apple Experience' has gone sour."

To be fair, that's a little bit of a silly position based on buying a first-rev new model as your first Mac. Whomever told you that was the choice to make when moving over to the Mac platform needs to stop giving such crappy advice.

$.02

No, it's a legit experience and if you sell a product you should make sure the quality is up there. It's no excuse to say, well it's a first revision system so it'll have some problems. That's on Apple not the new user trying them out for the first time.

I will say this though, even though it's sad this has happened I'd wait until later and get another mac after they've had some time to work the bugs out. Hopefully it does get better.

Oh, I agree that it shouldn't be happening. I'm saying judging the entire Mac platform based on his buying a brand new model on a new platform is not indicative over the overall Mac experience.

There's clearly no reason there should be so many of these out in the marketplace with problems, and to be fair, in this thread I've only seen one or two posts that suggest anything more problematic than a software or firmware update is likely going to fix...

but yeah, shouldn't be like this.

Please don't judge the whole Mac experience from this one model is all I'm saying.

I was being 'fair' when I returned the first defective one and gave them a second chance. Now the replacement one is doing the same. First-rev new model or not, Apples a big company who's been in the game a real long time. They would have picked up these issues if they had tested them properly before releasing them into the wild.

It's a silly position to be defending Apple when these issues are occurring, many more people coming out of the woodwork with this problem. Never had issues on any PC I've built or owned of this nature, and sadly this is my first experience with Mac and first impressions last.

Not judging the Mac platform. But I am judging Apple in this instance releasing the M1 Mac Mini with this issue when it just shouldn't be occurring. There's no support either from Apples end. We are just left twisting in the wind.

I think the Mac OS is just fine.

Started noticing this on my base M1 Mac Mini around a week or so ago during initial logon about 1/3 the way from the bottom of the screen, tried obvious HDMI cable change to resolve but no dice.

Has anyone else noticed responsiveness drop / 30 second beachball as the pixels occur? Applied latest update last night but not fully put through its paces today.

I also still see the pink squares after upgrading to 11.1, but right now I don't think I'm going to return it.

Why not? I literally only see the pink squares during boot (sometimes) and they disappear fairly quickly once I'm logged in and open an application.

After that they never appear again when working on the computer (so far).

When using sleep mode instead of shutting it down they also never showed up again. It only happens during boot for me.

All is performing great so that gives me hope that it's a software thing during boot.

Agreed, though one thing to consider (though I understand not everyone will do this, probably the minority) is it may be difficult to resell the machine in years to come on a platform like eBay if the issue is never resolved.

I usually don't sell my old macs, but a fair point indeed.

Since it's still early days when it comes to M1 and Big Sur I still have hope that Apple might fix it,. But for now we really don't know ofcourse.
