iMac 24” 2021 M1 backlight glow / bleeding screen

Not sure if you are aware or not so I will blurt it out. We are all end users just like you, Apple does not read or participate in these forums. Apple is simply our host. Your post read (at least to me) like you were attempting to address Apple.

If your computer is less than 14 days or less old you can return it for any reason. This assumes it was purchased directly from Apple. If you bought it from a reseller you need to deal with your reseller's sales policies.

Also, your computer is covered by a 1 year warranty, if you want to take it to your local Apple Authorized Service Provider they will look it over to see if there are any manufacturing defects. Also, if the computer is less than 60 days old and you have not purchased AppleCare I strongly suggest you do to protect your investment for a total of 3 years from the date of purchase.

To be honest, in the (almost) year the 24" M1 based iMacs have been on the market yours is the first post I have read mentioning any screen bleed issues so I suspect the issue is far from widespread.

Your welcome and good luck. Please check with your reseller to see if they will consider you returning the computer in exchange for another. If they are, before taking delivery ensure you power it on and verify the 2nd computer meets your standards.

Best of luck.

There was one other complaint about this- I don't recall that there was a resolution, finding the post though, ...

Thanks, 2 instances of an issue is still a remarkably small amount of complaints.

Indeed. Either folks haven't noticed (I have never looked) or it is a rare defect.
