Dark spots on display iMac 5k (Late 2014)

I bought one of the first 27" iMac 5k retina display. It is a wonderful machine and is working pretty good.

Last week when i switched my dark background screen to a more light one I noticed some weird dark spots on the bottom left corner of the display, I tried to clean it with a soft cloth then i found it that the spots are actually in between the surface and the display ( in other words unreachable).

Who knows since when that has been there, the case is I am now now realizing that my computer is off by 2 months from the 1 year warranty, took it to Apple store and I was sent back with a pretty much (too bad) we can't do anything about it.


I have done some research and it seems the problem is in more than just mine computer.

Question is, What is Apple doing about it? It is obviously something related with moisture/temperature or the new resin glue that they use on the 5K iMacs.

And of course the fee of 500+_ Dollars is a bit too much for me when I spend at least 3200.00 for it less than 14 months ago.


here are some images that show the spots.User uploaded file

I have an iMac 5k Early 2014, 2 iMac 5K have the same problem,

to me is less dust, with her brother's unbelievable!

It all happened after a year, when we lost a guarantee from Apple, the whole family all use Apple devices, after this, Apple will never again see my 1 cent! This is a shame, we have paid more than 3,000 euros per piece!

All of their devices I hung up for sale, since that's why! iphone 6, iphone 6 plus, iphone 7 plus, macbook air, macbook pro, ipad air 2, imac 5k!

After cheering from the iMac 5k, after a year of disappointment, at least all of their services are charged too expensive! 2017 is the year of Apple failure! trust me on this!

I went to the local Apple store and they said it is a defective housing and that screen needs to be replaced. Most likely it is dust/smoke that is getting in through the fan and then seeping out a small space and getting caught behind the glass.


They said it is a 3-5 day turn around and the computer needs to be left to be repaired. Not ideal. Mine is covered under AppleCare.
