I've read the first couple of gens of Retina were the most likely to manifest Mura White Spots. That: "you might treat it like a baby and you still might get it."

How likely are they on the last gens of Retina (the 2014/15 ones)?

And what about the post TouchBar generations?

So far, in my experience I've come to realize that it is (from most likely to less likely):
2012-13 Retinas < 2014-15 Retinas < post TouchBar gen
Would you agree?


P.S.: Mind we're not talking staingate. Just Mura White Spots, image for reference:

Had them on my Late 2013 15", had them on my Late 2016 15" Touch Bar model after a couple years. I'm pretty sure it's directly to do with pressure on the display. Closing the screen with hard particles between the display and the inside top case, for example. Pressure causing the backlight layer to show an indent on its otherwise perfectly flat reflective surface, but not hard enough to show an impact on the surface of the display glass.

From what I've seen, I think the problem is not from within (pressure between the screen and the keyboard side of the inside top case) but rather external.

i.e., when the MacBook receives excessive amounts of pressure, for example, when it's sandwiched between books and other objects in a backpack. Except it doesn't even take thaaaat much pressure to get a Mura.

Mura White Spots are literally cracks on the backlight, inside the screen's case.

I wouldn't suspect those particles between the screen and the keyboard as you suggested.

Either way, whatever cause it, it is something that happens nonetheless. What I was mostly interested to know, is if anyone else would agree that this issue is less and less likely to occur as generations of Retina and then TouchBar went by.

(So awful to have on a such expensive device, sigh...)

Ah - makes sense actually that I've gotten them on both my past MBPs. The late '13 and the late '16 models both were often smushed into a very tightly packed large camera backpack and traveled all over the world. Definitely a lot more external pressure than I would ideally want on them but had to do what I had to do. I honestly don't see an appreciable reason why the newer models would be more immune to this - the aluminum seems the same thickness and the LCD and backlight tech remains exactly as it was since the first rMBP in 2012.
