Appl maxOS. "eh, buddy, that's fine. Grab yourself an iPhone"
Linux. "Dude, it's GNU+Linux, actually. You need to RTFM before you are allowed in."
@claudius @aral I installed Ubuntu for 3 people who didn't use computers before (no prior MacOS or Windows knowledge) Two children and one senior citizen. That was 3-5 years ago. One of the youngsters sometimes whines because he can't install some windows only application. The other two only use the browser. I set up automatic updates and they all seem to be able to use the computer for what they want to without me holding any hands.
I think it's possible already for normal people to use Linux.
@claudius I'm not sure I would say that it's easier to fix MacOS or Windows by yourself if it breaks down. At least if "fixing" means something else than reinstalling the operating system. But probably we have different expectations.
