Build project for Linux and Mac

I’m trying to make a build for Linux and Mac, Mac has a lot of issues with it from the app store or I don’t know what. Linux seems to have fewer steps to build a project, I made a build for Linux but it doesn’t work, what build settings or player settings do I have to change to make my Unity project compatible to work for Linux and Mac? right now, I only care for Linux since I’m testing a demo, so I want to give a bit of extra access to Linux players.
