Yeah, that's the board I have — GA-Z77X-UD5H-WB as far as confirming: Full Graphics QE/CI - Don't totally know how to confirm exactly. Not using on-board gfx. Radeon 7950 works out of the box and is able to run 2 monitors at full resolution. Also got a good Geekbench score on it. Turbo boost - Working XMP - Working Sleep/wake without any problem - Working USB3 - All USB ports are working and functioning as they should (USB2 and USB3) Gigabit Ethernet - Only Intel is working. I installed the InstelMausiEthernet v2.4.0 driver with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] and I have Ethernet upon wake. Have yet to confirm speeds, however. Atheros will just not seem to work for me. Audio - Built in audio working, but I'm using a firewire audio interface (Saffire Pro 40) for my main audio, which is also working. SATA - All ports working. eSATA - Have not tested, don't need. iMessage - Had to run iMessage fixer, still having some issues syncing messages from my iPhone X. iCloud - works perfectly

Thanks for this! Made things way easier for me. Haven't redone my OS since Yosemite! I've got the Rev 1.0 board, and it's working great with the stock bios update straight from Gigabyte. Question though— have you had any luck getting bluetooth to work (assuming you have the bluetooth/wifi board)?
