The screens are glued and there is no glass on my screen, so where is this dust getting trapped? I'd like to add that this hasn't happened to my screen and I've worked on building sites a number of times.

The dust makes Macbooks overheat, the dust behind the screen is on iMacs which is a pretty common problem.
 
100% computers in the world collect dust... Apple happen to have the least dust and got sued. Now I wonder if these same people will sue Apple in another case where they claim Apple failed to make the iMacs water resistant?

Throwing your iMac in a pool or having it sitting on your desk and it getting “dust stains” are two completely different scenarios.

I have this issue with my 2015 iMac. No, I don’t smoke, don’t live like a pig, I’m not paid by Samsung or Google , and I’m not just looking for something to be wrong with my device. Considering I have it sitting on a desk and in a normal everyday environment I wouldn’t expect these kinds of issues when Apple prides itself on build quality which is what we pay a premium for.
 
I have that issue on my late 2012 iMac on both the bottom left and right corners. It‘s taking up a pretty big area and is especially visible on light backgrounds. I have no idea if Apple would do anything about it, especially since I‘m not in the US. Probably not, so I just learned to live with it.
Today’s iMacs and macbooks are glued together and not easy to fix. That’s a design flaw and Apple knows it. So if there are dust problems in about 5 years time, you should expect Apple to fix that at no cost. It’s reasonable expecting dustfree screens after 5 years of use at those prices. It was their decision to glue it together, so it must be their decision to repair that design flaw for free. Too bad a class action lawsuit is needed for them to admit.

Oh yeah? So why is it that when something like this happens and we call apple support, their first question is always if the user is smoking or has a dust filled room? Why not simply say that “every computer gathers dust it’s absolutely normal, we are sorry you shelled out 3k for an expensive thin iMac that now has dust inside the screen”?

Amen, so simple yet so hard for many apple sheep to grasp.

Computers build up dust on the fans and is normal maintenance to clean them if you can..

It is not normal for dust to accumulate on the lcd behind the layer or glass. If you had a TV and it slowly builds up dust you can not remove how would you feel?

My desktop has 4 air filters that are cleaned once a month. Lian li made the case and understands dust is a issue for everyone.

Apple makes it difficult to do regular maintenance like you are talking about on the HP. Everyone should clean their fans once a year or more depending on the environment. Then around 5 years consider new thermal paste and not a bad time for a new fan.

This is regular expected maintenance for computers. Taking a display apart because dust got into is not normal.
This is a complete "how comfortable are you in your ability to do .....thing..."
Yes. It is more difficult to clean the dust from inside an iMac.
Can I do it ? Yes
Do I feel comfortable? Yes
Does someone else? That is completely up to that person.


Whatever the thing is, there are places that will do whatever "it" is for you.

There are places that will change the oil on your car.
A place that will vacuum your car.
A place that will come and clean your house for your.
A place to drop off your clothes to wash them for you.
Places that will grocery shop for you.
Do your taxes for you.
Cut your hair for you.
and this list goes on and on and on for days.

Can a person do everything for themself yes and that includes cleaning the inside of a computer screen.
"SHOULD" a person do "whatever" for themself? That is completely up to them and zero of my business until they ask an opinion on a specific question.
People in general are ONLY going to do the things that have meaning or they deem valuable. They will not prioritize things that are valuable to someone else and not themself. If and when they do this, that's when feelings get hurt.
Ever have expectations? Then when that personal expectation you have is not met, you then get upset or judge the other person or company for not meeting your particular expectation? How about when we as people have expectations and then do not tell another person what the expectation is, then expect them to know what the expectation is, of course they don't because people can only operate in what is valuable to them specifically, so the other person or company gets crapped on because they were doing what is important to them but did not live up to your untold expectation.

I am not taking Apple's side, I am just saying on this very specific particular subject. I am just going to do it myself because I feel personally comfortable in doing that task.
Someone else may not. And that is completely ok.

And with that, there are some tasks I will pay someone else to do for me. because ---- enter whatever the reason is.

All I am saying is, I am not flipping tables and throwing blame towards someone that they "should" have prevented or did "this" or "did that" ..... I do not care.
I will however make a decision from that point, if a particular item is more trouble to me than I believe it is worth or causes me stress, I never purchase it again and I speak with my money to that company. I will reach out to them personally to make it right, if they do, then I have to make another decision. "Was it still worth it? Am I going to give them another chance? either way I will decide to do what I am going to do for me and then move on down the road to the next decision.

If someone wants to sue a company for whatever reason, that was their decision.

Again I am saying, I am not even putting my time or energy in to that. Because my reasoning is, I can correct this particular issue faster than the time it would take to even deal with a suit and everything that goes along with it. In that case my individual time is more important than the cash that might come from it.
Example: If I get paid $120 per hour for my time. And I can personally fix an issue within 1 hour. Then I worked for myself and paid myself $120 worth of service to get a clean screen.
If I have to put let's say 3 hours of attention into a legal issue or whatever it is, and I do not receive over $360 for those 3 hours then it was not worth my individual time to correct that thing.

Took a good look at the iMac Pro this morning and went and looked at a teardown report on the web. It made me feel a bit better, and I think the problem will be less on the iMac Pro than on others.

The "80% greater cooling" with larger fans will help. The main heatsink is right behind the air exit port, and so at least it can be vacuumed from the outside. The larger, big-diameter fans will help, but I'm sure will eventually get gunked-up, and of course surface components... if you get enough gunk, it starts to be a problem. So, will have to be opened to clean fans and boards. I would be cautious about the idea of blowing air through with canned air... you can inadvertently cause damage.

I see there have been several comments about smoking. OF COURSE people should not smoke around a computer! In fact, Apple sent a memo to employees a few years ago that they can refuse to repair computers that have smoke residue. Good for them! I can see that this could be a work-place hazard if you do this all day! I hope they wear dust masks anyway!

I'm old enough to remember, though, working at a place where the entire IT staff smoked, and that's before people went outside to smoke. Take about nasty keyboards!

Exactly what I did.
Not worth fixing after you run out of warranty. Cost is too high while you only get the new replacement with same old problem that will haunt back later. Not to mention it's also the same old computer that may be too weak today.

I don't give a $ what you do either, but it's a forum where I can share my knowledge and experience in hope I can help someone with the same problem, in this case a very common problem.

You were saying as if it's okay Apple sells you faulty design for years. Now if you have a Mac computer that gives up the ghost just one day after the warranty expires, what would you do? Smile and move on? Wow, you must be Jebus!!

Fix it is also weird phrase when it comes to Apple. You don't fix Apple stuff. You replace it even though only a small portion of the assembly needs fixing. Dig a bit deeper and Apple wouldn't touch your computer.
Well this is where I agree with you but no I think just the communication of texting and forums don't show emotion or can lead to incorrectly showing values. I do agree it is an issue, but for ME, only me and myself, it is not THAT much of an issue only because I will just fix/repair/replace it and move on.

On the question of if it dies and the day after the warranty. I will take the product in person and explain and give them the opportunity to still make right, because I have been in that exact situation before and it is what the company does at that moment will determine the next decision I make. And I deal with dozens and dozens of companies, not just Apple and they all get the exact same chance to handle my issue. If they give me a good experience, I tend to stay with them.
If they give a bad experience, then I make the decision to start looking for another company to do business with. But I will ALWAYS ALWAYS give them at minimum a second chance because, things happen. Companies are run by normal people and sometimes they have bad days or $ happens. I understand. So I give them a chance to recompose and see what they do.
If we have bad experience #2, I am usually moving on at that point.
 
I can't think of any laptop that has dust filters to be honest. Desktops yes but not laptops.

That was my question also. If they are going to file a class action suit over this and no manufacturer does it then they should all be sued or clearly they are only going after Apple because of name. And lets be fair, it takes more than a year to get the kind of dust these folks are talking about, so why the heck didn’t they get apple care if they knew they wouldn’t be changing machines every year. Or you know, take it until a shop every six months or so to be cleaned. My local apple store doesn’t even make me leave our company laptops for this. I book an appointment for them a couple at a time and they take them in the back and open them and clean the fans etc within about 10 minutes.

Had the screen replaced twice on my 2010 iMac because of this and once on my late 2012 machine after it was out of warranty, I said it should be covered under the 6 year european sale of goods act and that the fault was inherit in the design, when i said that they replaced the screen.

Just so you know they didn’t replace it because they agree with you. They did it because it’s just not worth raising a fuss. You say it’s covered and they say no it’s not and then you go to court so you can prove that it was a flaw at delivery and they have to defend that no it wasn’t. Blah blah. It will cost them more than the $500 or so (or whatever the equal in local currency is) to do all that. So they just give up and give you a free repair and ‘make good’, thus saving themselves a lot of time, money and of course the press that might happen

I don’t smoke, but I live close to an highway. I had a 2012 iMac, and an apple thunderbolt screen that developed this problem. Both fixed for free because of AppleCare. I sold them both.

Want to know why I sold them? When I picked my TB screen at the apple store, the store next to them was being renovated, and all the iMacs in the store showed this exact problem, just much worse.

Bought a nice dell screen, changed macs a couple of time (now running with a mac mini), I live in the same location and no dust in my screen after 5 years in a « dusty » environment.
I hope you’ve bought the cheapest edition of the macmini. The more expensive ones with better processors can’t handle the heat and will thermothrottle it down so far that the one with an i3 ends up faster.

Another class action suit needed to get Apple to take actions on their faulty designs. Same for iMac and iMac pro.

Please explain to us how a constantly cleaned NYC apartment, several stories up, with the computer a good 15 or 18 feet away from the window with a 4-in-1 HEPA filter about 6 feet away is an 'extreme environment'?

1. He said ‘generally’ not ‘always’
2. No you can’t google and find millions of cases. You can find millions of posts of which dozens are by the same party
3. Not everyone lives in an apartment like yours so stop acting like they do
 
This thread has quickly grown and I haven't got time to go trough all the posts now.
Just wanna share my opinion with you.

Old MBPR has been designed in a way that allows you to open the bottom cover and clean all cooling components off dust easily. Even better, you can remove the cooling assembly and replace thermal paste on the CPU without voiding warranty.

The new MBP (I've looked at the 2018 models only as I've fancied purchasing one) were intentionally designed to prevent you keep the warranty if you want to detach CPU from cooler in order to reapply thermal paste on it. I was sad to see that.

My first thought was to take the new MBP to Apple Store for a cleaning and thermal paste job but that idea soon faded out as I have not been particularly happy with the quality of work that they did on my 2013 MBPR back in 2015 when I've had it in for warranty repair.

All in all I was really hooked in to buying the new 2018 MBP.
Then the KP problems started and I gave myself some time to see the real fix, but it never surfaced.
I thought that Mac Mini would come in with T3 and free of the KPs - it did not happened.
The new "new" MBP came in and I just do not trust Apple my $4k for a laptop.

For what I do a Hackintosh will provide perfect firepower and upgradeability in desktop form factor for next 5 years to come. And I'll keep using my 2013 13" MBPR as a daily light work runner.

Apple has disappointed me in all the fields they could pull a disappointment at.
MBP Keyboards, MBP poor thermal solutions, T2 Kernel Panic, iMac Core i7 thermal solution, overall price is insane in EU...

I would remove the KP from the list of disappointments if Apple would have released a statement about the problem. They are acting dumb about it. You can call Apple and they will preach for hours about third party apps that are causing problems but they know it is all their problem. I've asked many times if they can prove that Autodesk Fusion 360 runs on the machine I wanna buy and it was impossible to set up in store test. Why is that not possible for a 4k machine?

I am not buying any Mac products until they sort this saga out.

So glad that someone is pushing this case. Poor Steve once said "We just can't ship junk"

I had same problem with 2013 27-inch iMac which I bought second hand - bought from advertising agency it probably collected dust from area where printing machinery was located. I had similar dust as in the picture.
 
Yeah it sure is fine when dusts only trapped inside your computer. We live in planet earth after all.

Problem with iMac is, the computer is also where the LCD assembly sits on. If the computer gets dirty, so does the screen. And even worse with iMac, the dust gets trapped INSIDE the LCD layers.

When you have an all-in-one, screen is the main show of the computer. When the screen gets smudged with dirt, and you paid $3000 for that machine, you'll know you have to be mad at someone. Sue them? Why not!!

Having had to clean this on a few very old iMacs, it's not trapped "inside the LCD layers" - its trapped between the front glass and the panel itself - a user accessible space.

Over a long time, a shadow of dust can form at tiny voids between the air circulated area and the display glass. In much older iMacs it would form around the opening for the microphone/camera.

Also, if the cover glass or panel ever get handled by an assembler or technician, the smallest amount of oil from the hands can also act as magnet for this very fine dust. A fingerprint from years ago will eventually start to reveal itself.

On the iMacs where the panel is held on by magnets, this is a 5 minute fix. With the advent of the adhesive strip being employed, its a far more difficult fix, as one needs replacement adhesive strips in order to replace the cover glass.

Exactly. Apple Mac computers never had a great cooler to cool CPU and GPU. That's how Mac Pro 2013 messed up.

My 2010 iMac has light smudges in the upper left corner, most visible on white backgrounds. Learned to live with it, but bummed out not seeing a new iMac this year, as I cannot got to Mojave.
 
I suggest you put it on sale while it's still running. I've had the same problem with dirty display on late 2012 iMac with 680MX, but it died just two months ago due to GPU failure. I was kinda grateful it died though so I can have reason to get a new computer. That was the deal with the wife LOL

Now I have a custom built PC that runs even faster than maxxed out 5K iMac. Get yourself a Mac Mini if you have to stay with Mac. I wouldn't touch Mac desktop for workstation. Way too many compromise and design fault just because Jony wants it to be 0.5mm thinner.

My home desktop is for work, making a living. I can't put it at stake just because it looks sexy.

I doubt you would want to expose your custom built PC to the same absurd level of criticism from others.

I wish Timmy Cook and Ive would see this movie and looks what they’ve been doing with Apple computers since 2011. I said this before and I’ll repeat it again. They ruined the soul of this company. They’re selling faulty designs. Thermal issues, touchbar disasters, and glued unrepairable not upgradable last years tech at above premium prices. I once told all my friends and family to go Mac. I don’t recommend that anymore.sad but true.
