This is too accurate to be mad. 

Well then I guess it's only fair Windows gets an "accurate" one for the mac too

Honestly that's just a bit sad really.  For one thing, they're hardly perfect either.  For another thing, it's not like this is an ad campaign or something like that, this is something built into the OS.  Not super classy to disparage competitors in such a manner imo.  Just looks childish, which I think is backed up by the fact the icon is clearly a joke, given the depiction of what they seem to think a typical Windows machine is.

You can barely make it out when its on a 4K screen with decently large icons tbh

1080p its not noticeable at all

Its more of an easter egg to me IMO

You can easily tell what it is though.  I'm surprised you of all people would say that considering how you're always talking about how you run your 9K 3" phone at 100% scaling and read it from 20 ft away
