Ah hahahaha I registered an account to this forum specifically for this post.
I was looking for the solution to this,
weird and unreasonable yet without a doubt Apple's taste which WILL make people pain, as well.
In short, Apple makes you hit that CapsLock button and put your finger on it for a, so they called it, "SHORT BRIEF" of time, to actually make it work.
If you just type it as you would do to any other keys, it won't work.
This key-pressing setting is not written on any manual or any webpage or being told to you by any of the li'l geniuses in the Apple store nor does this exit on any other keyboard on this planet, before you buy that Apple laptop and actually use it. It's more like part of the phrase written on Apple's Golden Bible shared by mouth between Apple worshipers. So if you don't know, you don't know. They wouldn't tell you meanwhile they loath the fact that you don't know. To 'em, Apple is pure and unchallengeable.
As in why would Apple do that? Probably as
Aggedor has pointed out, Apple thought you might,
funny enough but whatever, ACCIDENTALLY hit CapsLock and cause unwanted typing issues.
In the meantime, over 75% of all computers are WinPCs and they are out there doing alright without this tedious, as they call it, a SHORT BRIEF of time but actually long enough to annoy people key press setting.
I have once asked about another weird thing that Mac has got and someone replied with this which I thought is really to the point: ... in order to fatten their already morbidly obese bottom line.
