In order to use Mod Central on macOS you need to Install Windows 10 on your Mac with Boot Camp Assistant or [PAID/TRIAL] with Parallels Desktop or [PAID/TRIAL] VMware Fusion – or [FREE] VirtualBox .
In this use-case you will likely not need to purchase a Windows 10 licence key – Although cheap online – as long as you’re happy with limited customization (i.e cannot change desktop wallpaper for example).
Your Mac can have as little as 64GB of free storage space, but at least 128GB of free storage space provides the best experience. Automatic Windows updates require that much space or more.
Some older Mac models were offered with 128GB hard drives as an option. Apple recommends 256GB or larger hard drives so that you can create a Boot Camp partition of at least 128GB.
