Emulator for Mac OS X?

[theSelfCalledNowhere]

Hey. I'm new to forum, and I'm new to modding. Like modding anything. At all. But the idea of making new maps for ETS2/ATS really intrigues me. So I want to give it a shot.
Small barrier though before I begin: I... don't have a PC.
The only computers I have at my disposal are Macs. I currently have ETS2 and ATS installed on my Mac through Steam. But I've searched high and low and I just can't figure out any way to mod on Macs. Here is a question I have - is there a recommended emulator through which I can start modding? Can I mod on Windows on Mac, essentially? If so, is there an emulator anyone recommends?
Thanks.

It will be the safest if you install Windows 7 or 10 via Bootcamp. We used emulators like Parallels once but they were quite unstable.
