The windows one likely have them, except they have the codepaths for all processors.

Yeah, restricting the hardware your software can run on is super cool!

This happens in Linux apps as well. Vendors like Discrete will have restrictions on what kernel version, which distro, what hardware that is really no different. With a Mac, you just don't have a choice on the hardware to install. On Linux, you have a choice, but only from the 2 options listed and you have to build it yourself.
