No idea sorry. I put the system together to tinker with some iOS dev, but lost interest after a few months. I don't use any of the rest of the Mac ecosystem, so not sure how that functions.
What's special about iMessage/iCloud which poses an issue on a hackintosh?
Messages, Facetime and iCloud work for me on Sierra on my new hackintosh without any fiddling. On my previous Hackintosh, which I believe is running Mavericks, those services don't work.
I ran into this too. As far as I know, nope, it has not improved.
