Not really. There's rather large quantitative difference. Vast majority of user facing PC OSes are not run in a VM, or are run in a VM only from technical perspective, not in any user-visible way. Compare that with writing code to bare metal, which practicly no-one does (even if assembler counts are bare metal).

You presume that the person likes MacOS or has some reason (like a particular app) to run it. If you want to make such presumption, it's fine by me, but you have to spell it out. My default presumption is that people usually get by with just one OS per computer.

I agree with them, but don't really see how it's relevant to what you asked. You didn't specify any particular needs.

I don't particularly like MacOS, but I don't particularly like Linux desktop managers either. Main reason for that is that I don't want to waste my time learning to fluently use several OSes, if I can get by with one. Both MacOS and all flavors of Linux have limitations that make them less than optimal for my personal use and pretty much impossible for professional use.

So now that I've explained that one OS is enough, do you still think I should run it in VM under some other OS?
