I don't buy Apple Care as I usually buy new devices after 2-3 years. It's a common problem so Apple should look into this and should have a service plan for it.

It's unfortunate and I agree a screen should last much longer than 3 years. I am using an iMac here, 2015 model. Recently recycled an iMac 2008 that failed because of its power supply, not the screen. All computer makers purchase in bulk parts for their products from third parties, there is an acceptance of a certain percentage of failures or defects, maybe a percent or so. At work, we have quite a number of iMacs and Mac laptops, I noticed that my employer now has Applecare+ on all of them. And we are required to replace all computers every three years at work. I have never seen one of those iMacs fail, so the percentage might be low.

All my personal Macs are laptops or iMacs, which have a lot of chips and hardware fit into very tight spaces. This makes them prone to thermal issues or other internal connector problems, hence I always get the Applecare+ and consider it simply part of the cost. We have actually never made a claim for a Mac (we have had many, so I guess we have actually lost money on buying the Applecare+ there), but my daughter has had two claims on iPhones which resulted in new phones.

Nope. I don't use this device quite often and I have an external monitor so it doesn't really bother me that much. Repairing it costs more than 50% of its original value, thus it is better to buy a new device than repairing it. It is for sure a manufacture or design defect. I will not buy this device if they tell me that the monitor will fail after two years. Apple should launch service program for this issue.

If enough people tell Apple about the problem at iMac Feedback they might do a recall program on it.

I am having the same issue. Bought mine in Dec 2022. And horizontal lines started appearing on the screen and has been flickering since. Had Apple call me and unfortunately, they say they can't cover the repair. Disappointing. Especially that it appears to be a design flaw as it's happened to multiple users of the same product.

Same issue just came put to my IMAC M1 yesterday. Screen flickers and there is a black spot at the upper left part of the screen that is very hot. I was told to send it for repair to change the screen and it cost 43000 php.

I’m experiencing the same issue with my iMac 24” M1. I purchased it in August 2021, and today I encountered the same problem. The top part of the screen shows lines and flickers. Additionally, the top left corner of the screen becomes extremely hot to the touch, almost burning my finger if I hold it there for more than a few seconds. I’ve noticed that many people are experiencing similar issues with the iMac M1 chip model. Apple should address this issue immediately and provide a permanent fix at no cost. Otherwise, people may lose trust in Apple products. At the very least, there should be a software patch to resolve this display issue in the iMac M1 chip model.

Gulp, I've seen prices like $800.:(

See here...

Persistent horizontal lines appear on iMa… - Apple Community

In Singapore it will cost approximately S$900 including GST.

Well I understand and I have seen about 200 posts on these forums about it, I have no idea how many machines that represents however even if it's about 500-1000 machines that is a relatively small number in the grand scheme of things. It's definitely no fun when it's your machine and you don't have AppleCare though.

I suspect you represent a very small minority in that you only own your devices about 2-3 years, my current machine is 4+ years old (2020 27" iMac) and I plan on keeping it until as long as it can run current versions of Mac OS. That being said, your machine needs may be significantly more demanding than most so buying the latest and greatest may make a lot of sense. Even if you only own 2-3 years AppleCare may make sense for years 2 & 3, that being said obviously it's your decision and as I mentioned already this time your number just came up!

I’m experiencing the same issue with my iMac 24" M1. I got it in June 2022, and today, I encountered the same problem. The top part of the screen shows lines and flickers. Additionally, the top left corner of the screen becomes extremely hot to the touch, almost burning my finger if I hold it for more than a few seconds.

What is the update on this issue now? I have also started getting the same problem with my iMac which I purchased in July 2021 iMac 24inch M1 chip since a month now and still no progress on any solution from apple.

I have an iMac M1 24 inches purchased in January 2022. For now everything is fine, but I'm afraid that I might have the same problem soon. I previously had a MacBook Air and the famous butterfly keyboard problem, which Apple replaced under its repair program.

I know there were lawsuits in the US against Apple to force them to fix this problem for free. I hope it will be the same with horizontal lines now.

If my iMac breaks down too and Apple doesn't fix it for free, I give You my word I will never buy anything from them again. Apple will cease to exist for me, I will go back to Windows.

Of course I will leave feedback and write what I think about them. Maybe if a few hundred thousand disappointed users do the same they will be scared.

So far, reading Your posts I am very disappointed.

It is hard to tell from the number of posts here. We are an emergency room, we might be seeing the majority of the cases, or maybe only the tip of the iceberg, it is hard to tell.

Only Apple can tell for sure, since they now how many screens are being used for the repairs.

I too have the same issue I took this in 2021 and display is costing very high Rupees 54000 in India, Looks like apple should do this for free seems many are having this issue and definitely this seems like a manufacturing defect. :(
