I assume the `tr` is to avoid detection, there's a tiny bit more info here: https://www.nicksherlock.com/2021/06/installing-macos-12-mon... (grep for 'OSK')

Seems people really avoid saying the value, ('don't be surprised it doesn't look like a random string') maybe there's some history of Apple requesting people cease & desist wherever they find it, I don't know.

It's easy enough to search for "isa-applemsc":

https://github.com/search?q=isa-applesmc&type=code

I'm guessing it's more of a philosophical stance rather than avoiding detection. Like "Apple isn't going to make me put the string 'dontsteal' in my repo".

Fair enough, I just had no idea to search for that. (I searched 'OSK' because that was the variable name and it seemed not specific to quickemu.)
