A site where you can open other sites with a "disguise" desktop?

Question

Computer networks

Hello.
Are there any sites where you can open another site as if you are watching it from another operating system (so that not only the browser is different, but the entire desktop). I have Ubuntu, and I need to take screenshots as if I'm running Mac OS. Is there something like that?

Answer 1

You come up with some complex solutions. Virtual machines will save the father of Russian democracy.
