MacOS support added

I've uploaded a MacOS version; it's worth to mention that this version is mostly untested since I personaly don't have the hardware to test it on. So I can't give any sugguestions about hardware requirements or potential issues. That said, a few people had tested it and the version was functional on newer hardware as long as the GPU was powerful enough and featured neough VRAM (I guess everything from 4GB VRAM should be fine).

Any feedback or bugreports are welcome - just drop them in the comments of this post to inform other users; share your experience and maybe even fixes. 

Thanks :-)
