M1 iMac Owners Complain About Horizontal Lines Appearing on Screen

The G4 Powerbooks with their faulty hinges. Faulty 2007 Macbook Pro GPU. iPod Nano's being easily crushed. USB power adapter. Issues with the first Intel Macbook Pro. I'm sure there are many more I can't recall.
Things have changed at Apple, I used to have good luck with getting things like you mentioned fixed, but Apple now takes a HARD stance against fixing anything or doing anything for anyone that doesn't have applecare on a product... even if it's a manufacturing defect. The will now flat out tell you "it's your problem, too bad".
My last two encounters with Apple have absolutely turned me in the direction of moving away from their products, unforunately.
A glaring issue is the $600 (after tax) Airpods max that keep failing people, they no longer pair with peoples hardware and then fail completely for no reason. I had a $600 pair that never left the house and were in mint condition, they started having problems and just bricked... at 14 months of ownership! Never been wet, mishandled, or abused. I took them into Apple and the absolutely refused to do anything for me even though it's well documented throughout the internet that this is a manufacturing defect in a lot of these headphones. It shocked me that they didn't care that their $600 headphones failed me after a year and told me I should have just bought applecare.
I also had a problem with the battery in my Iphone a year ago, and again they refused to do anything for me. They just don't care like they used to... it's no surprise that their profit margins are way up, they have taken a hard line stance to leave customers with defective products!
And I am THE biggest apple fan and everything I own is Apple. I am slowly and methodically getting away from Apple given this new strategy of leaving customers holding expensive useless products because of THIER manufacturing defects.
Never saw this on mine. Small batch of defective displays that showed up? Yes I also extended AppleCare.

He did! The top right one as the article says!
My M1 iMac can get noticibly quite warm around the bottom when I'm on a Zoom call with a lot of participants, or doing other intensive work like transcoding a video or something. I never audibly hear the fan, but I know it's running because warm/hot air is coming out of those bottom vents.
I haven't seen any sign of display anomalies, but fortunately I did extend my AppleCare recently so at least I'll have recourse if it goes bad.
Dustgate issue
I have macbook pro M1 pro 14inch… have vertical lines.. went to apple store and they cleaned flex cable but issue still persists… then they asked me to pay $700 to replace the lcd screen …… this is a known issue on macbook pro models 14inch
I am just haning with one think veryical lines… people confirmed that it was a design issue which was fixed with M2

No mentions of Apple’s first “smart keyboard” for the iPad Pro with the three pin connector on the side?
Apple’s patent was for conductive fabric through the hinges instead of wires. The unplated, bare copper traces oxidized from the slightest amount of humidity in the air and eventually corroded until the dreaded “this accessory is not recognized” error flashed on the screen.
There is no fix other than $169 replacement. All keyboards exhibited this failure at 18-24 months. I think mine lasted 14 months.
Pure garbage design with poor material choice.
My 2013 iMac is still going strong. Win some, lose some.

Same for me I went to Apple Store and told me to buy a new iMac not even a year later grrrr bad apple for service.
Over the past year and a half or so, some owners of the 24-inch iMac with the M1 chip have encountered horizontal lines abruptly appearing on the computer's screen. There are complaints about this issue across the Apple Support Community, MacRumors Forums, Reddit, iFixit Answers, and several other websites, but it is unclear how many customers are affected in total, or what the underlying cause of the problem is.
Many affected users said the lines began appearing on the screen around 18 to 24 months after they purchased the iMac. As a result, the affected iMac units are often no longer covered by Apple's standard one-year warranty at the time the issue begins, unless the customer purchased extended AppleCare+ coverage. Some customers who contacted Apple about the issue said the company offered them an exemption, resulting in their iMac being repaired for free, but other customers said they had to pay for service.
One symptom commonly mentioned is the top-right corner of the iMac becoming hot to the touch after the issue begins, but there is no confirmed cause.
Given that these complaints have been continuously popping up for nearly two years now, there may be a hardware issue with this particular iMac model, which launched in May 2021. We have not seen widespread complaints about this issue affecting the iMac with the M3 chip, although that model was released less than a year ago.
Apple offers service programs for some hardware issues, but it is unclear if it will ever launch one for this iMac issue. We have reached out to Apple for comment on this matter, and we will update this story if we receive a response.

Just to confirm, this issue is affecting only M1-based iMacs, while M2 and M3 iMacs remain unaffected. Is that correct?
They had the choice to use mSocket graphic cards, but refused because the ports would cost 5 cents extra to purchase. And the gpu themselves would have cost $10-15 each more.
like an iMac of the time 2007-2015.
Can’t waste that extra $20 per machine.
Have to MAXIMIZE PROFITS.
I still have a Mac mini CORE SOLO that runs realtime network analytics for me at the shop.
It’s running Linux but it works FLAWLESSLY.
Maxed out the ram at 6GB, 128gb ssd.
I don't disagree. It was just that we had the AppleCare on the device, and it was covered under that plan.
The problem we have with quality control at Apple as they now have a conflict of interest.
It only suits their financial interest up to a certain point to make things as good as possible.
Beyond that they would like to have you have to pay even more money for extra coverage to deal with issues they created

Hopefully they will do the right thing if people do not have AppleCare. Our device was just 2 years old when it had this issue.
Apple sell premium products. They should last 2 years without issues.
At minimum, Apple should offer a full 2 years coverage as standard.

I totally agree.
After getting burned on my old MBP with display issues, I just lunk out the $100/yr for AppleCare. I never did it before, and I'm not a huge fan of extended warranties. But I really got the hose on my old Mac and I just don't want to go down THAT road again.
I also got AppleCare on my first gen Ultra watch. After seeing the cost to repair that sucker. I do that month to month.
As I get older, I find the piece of mind is worth the money to me. Everyone is different. I'll probably shell out for the extended warranty on my next vehicle as I'm just getting to old to crawl under them in the driveway at this point.
See this is my problem with all in ones. Is it the display component or the computer? Using a Mac mini or studio you can just put another cheap $200 display down (or buy used for even cheaper). With this you need to send the whole computer back.
I know this is highly controversial considering the immense amount of requests for 27+ iMac. But in the long run I don’t find these worth it at all. I went through my share of issues with the 2017 27” iMac.

I have a Day 1 M1 Pro-based 14-inch MacBook Pro - no issues what-so-ever. It works flawlessly....Might just be a defective batch of M1-based iMacs that have this issue....
Not a problem in Australia. Products need to last a reasonable amount of time regardless of manufacturer warranty.
In the case of a desktop computer that costs thousands of dollars, 3 years is the absolute minimum I would expect such a product to last. Even if the iMac is 5 years old, threatening to lodge an ACCC complaint should be enough to get the device repaired or replaced for free.
It's not new, it's an iMac tradition that predates Cook. My wife's G5 died in a similar way and so did my late 2009 i7.
