#Bluish Spots# Please Check the screen of your MacBook Pro 2016, 2017, 2018

I also have this issue on my Macbook pro 15" 2019 model.
Still under Apple Care, will make an appointment with Apple Support later.

This is my second display replacement with the issue. Two blotches across the centre of the screen and now a large blotch appearing to the left.

Is this issue happening in M1 based MacBooks and when mainly using them in clamshell mode?

It would be interested to hear from MBP 14 M1 Pro and also from MBA M1 owners who have been using their MacBooks in clamshell mode mostly. I'm considering replace my Mac Mini M1 with MBP 14" Pro so I would be using it 99% of the time in clamshell mode and plugged in to charger using my 32" 4K monitor as display only. I currently have also MBA M1 I use rarely, so I was thinking about getting rid of my both Mini and MBA and use this single MBP for all my use where I rarely need a laptop really. I'm just not sure this is really wise thing to do.

Also how common is battery swelling in these when constantly plugged in?

I'm not sure it is somehow related to clamshell as I supposed to think some time ago...
My personal opinion is that the main reason for battery swelling and spots appearing is chassis temperature.

I had 2 MBPs (one in clamshell mode always, the second always standalone) - both have bluish spots and batteries swollen in 2-3 years.

I have my current MBP (mostly in clamshell) for 3 years already. But from the day one I installed MacsFanControl and set more aggressive cooling policy. And no problems so far.

2016 13" here. No problem. Well, at least for this issue- I've already had my screen and keyboard replaced for flexgate and butterflygate.

Now my camera has stopped working again, looks like flexgate is back and the free repair program is no longer around.

So all good, lol.

Heat sounds like the most plausible reason for this but I guess battery swelling could have caused pressure against the display which might result something like this too.

I guess battery swelling might have been more issue of battery design/problem generally since it seemed like it was common few years ago but might also be partly from very hot running Intel CPU's. So hopefully M1 and M2 will be better for the battery due to less heat. Just not sure about MBP 14" and 16" since M1 Pro/Max chip in those seem to run a bit warmer than in basic M1 based Air or Pro 13".

Interesting to see if this still will be issue with M1 based MacBooks, I just started using my MBP 14" in clamshell mode all the time.

Have you been using clamshell mode much with it?

I have a 2018 and I have the same problem. Apple does not want to fix it for free, but I think it should. This seems like a manufacturing defect. Probably a glue or something they use to make the panel.

I have a 2018 MBP 15" and have a similar blue splodge pattern on mine.
If it was image retention or burn, it wouldn't always be blue, and some of these patterns are similar to others.
It was a corporate machine and a few other people have the same.
I recently got a 2022 M2 Air, not noticed anything so far, I mean perhaps there's a slight slight blue small area to the left but hard to notice it. I'll keep an eye on it though. My thoughts were a glue getting cooked bad by heat over time.

Having scrolled through the thread I see quite a few which look very similar to mine, like a large € shape on the left and mirrored on the right almost with an eye on each and a line between them forming in the middle...

I have a macbookpro 2017 and have the same bluish spot in the center of my screen. Its very faint though so not sure if its worth having the screen replaced

I recently bought a used MacBook Pro 15" (2018), and everything is fine except for some blue spots on the screen. They are very faint and hard to see with the naked eye, so I increased the contrast in an editor to make them more visible. From what I understand, there isn't a definitive explanation for why this happens. My guess is that it's due to pressure. If you carry your laptop in a backpack and the contents press against the screen, these marks might eventually appear.

To test my theory, is there anyone who has experienced this issue but has never carried their laptop in a tightly packed backpack?
