I looked at the upcoming Asus Z390 motherboards, too, and the specs sound great. (I really like the improved VRM.) I'm particularly interested in the Z390 GENE. However, as @Skripo alluded to, some of the new integrated features may not be compatible with macOS yet.I'm assuming the Z390 motherboards will take advantage of the new built-in Intel Wi-Fi. Some of the H310/B360/H370 already take advantage of this feature. The motherboards that feature this have a card plugged in to a slot that is physically the same as a typical M.2 (A/E key) slot. However, these slots are only compatible with Intel CNVi cards. This means that using a BCM94360CS2 with an M.2 adaptor or DW1560/DW1830 cards won't work with these motherboards. Therefore, the slot and included cards will be useless until Apple adapts the technology and adds drivers to macOS.Secondly, Intel now includes USB 3.1 gen 2 with the B360/H370/Z390 chipsets. This will probably mean that Z390 motherboards will no longer use ASMedia chipsets for USB 3.1 gen 2, which macOS had native support for. Again, until Apple adapts this in to real Macs and includes drivers, these USB 3.1 gen 2 slots will be useless to us.If you don't mind these two issues, I amthat Z390 will be fairly easy to hackintosh because of the extreme similarities to Z370. As far as I know, besides the two above features, Z390 is essentially Z370.
