Well,
the new Hackintosh are based on the Z170-boards. tony updated the buyers guide a few month ago.
there is a very interesting one: Gigabyte Z170X-UD5 TH with 2 x thunderbolt 3 on board, which are fully working, but don´t expect hot plug. all tb-devices need to be pluged while starting the machine.
I am preparing a machine for one of my customers soon.
I also have 2 others in my office, based on the older Z97, one built on an asus-board, another one with gigabyte as well with 2 x TB2 onboard.
it´s a bit of learning-curve to prepare these machines, but finally, if thery are working, a good and more cheep alternative compared to apple.
