We should write it "MacOS", following the normal convention of proper
names in written English, because we have no reason to depart from it.
On general principles, in the absence of any reason why we would want
to depart from them, it is good to follow such conventions.
The only proposed reason to write "macOS" is that Apple asks for it.
Since Apple is an enemy of the GNU GPL, and an enemy of computer
users' freedom generally, a request from Apple is for us no reason at
all.
No.
"macOS" should be written "macOS" because that is the name of the operating system. There are no further considerations to this.
As you know, brand names are not English words and do not abide by their rules. "eBay" is "eBay" and "BMW" is "BMW".
It's OK. I was only trying to help, assuming you'd like to know. Once you are aware of this, it is your call.
We can close this issue folks.
