I'm a Python programmer that is trying to make a system of sorts that creates save data for a game I'm making, and I want it to be in different places in something like Ubuntu than I do macOS. As I don't have a macOS, and it's impossible to just up and get an ISO to get a macOS VM, I can't look through the files and folders and see what it has (or doesn't) that Linux does or doesn't.
I've tried looking all over to the point of attempting to get a hold of an ISO to build a VM in VirtualBox, but haven't been successful at all.
What files or folders does macOS have that Linux does, or vice versa?
To complete the (excellent) answer from @Michael, here is the listing of the home and root directory after a fresh install on the latest stable release of MacOS System (10.14.2)
