I'm pretty sure MacOS and most of the headless Linux distributions require you to install it (from a package manager or similar). It's not hard, but usually the alternatives aren't hard to install either.
I've never had that issue. Make existed on all Mac systems I've worked on. Perhaps it got pulled in via other tools, but recently I ran into an issue with the Make on my Mac, and only because the version out of the box is a 3.x, from 2006.
