(It generally does not. Instead it uses more lightweight isolation primtives. That has always been one of its main selling points.)

It very much depends on what you are running inside the containers. I regularly have a dev environment with ~8 relatively lightweight containers running on my Early 2014 MBA without any problems.

Docker for Mac very much uses a VM. It's as lightweight as it can be (using the OS-supplied hypervisor, not something third party), but still a VM.

The context is on MacOS. Docker is a Linux technology, it runs Linux containers, thus it requires a Linux VM to run Docker on a Mac.
