First of all, thanks to philipjdall for the details about using the same motherboard for the setup and providing the EFI files

My previous hackintosh was built in 2015 with Gigabyte GA-Gaming3 MATX and Intel 4790K, GTX-980Ti (changed to RX580 later-on), it was working fine but I want to shrink the size of the desktop so I tried to build a new one with smallest possible chassis using iTX board.

Here is the configuration
  • Gigabyte Z490I Aorus Ultra ITX Motherboard
  • Intel 10700K processor
  • Corsair Vengeance LPX 64GB (2 x 32GB) DDR4 3200MHz
  • BCM94360CD with M.2 adaptor
  • HIS RX 580 IceQ X² OC 8GB
  • 512GB SSD from old device
  • Corsair SF750 Platinum power supply (with custom made cables)
  • Noctua NH-L12S cpu fan, Noctua case fans
  • A4 10L size iTX Case
Working
  • Everything - Ethernet, wifi, bluetooth, audio, USB, Sidecar, Handoff, Airdrop with the EFI files from philipjdall without any changes
Not working
  • Apple TV, Netflix with Safari (Chrome is ok)
Points to note
Building with smallest chassis and iTX board will have some challenges including the installation of the BCM94360CD card, antenna connection and cabling arrangement.

For the BCM94360CD card, it is a bit wider than the M.2 slot at the back of the motherboard so it is not stay flat on the board, I used some double size 3M tape to fix it. Using BCM94360CS2 may be better.

For the wifi/bluetooth antenna, I do not want to remove the existing wifi/bluetooth card from the mother board and route the BCM94360 antenna cable to the original backplate. I purchased some FPC antenna with correct connector (IPEX1 for BCM94360CD) and stick those FPC antenna at the top of the case near the case fan. Bluetooth /Wifi Reception may not be the best but as I use Ethernet and bluetooth is only used for airdrop / airpod etc. Speed is not a concern to me as long as it works.

I have also bought an internal USB3 -> USB2 connector to connect the BCM94360CD to avoid sleep problem

What adaptor are you using with your BCM94360CD?
 
I am using this type of adaptor

Some updates, bluetooth reception was not good for airpod use, so I built an external antenna box and connect to the BCM94360CD. Excellent bluetooth and wifi connection after changing to this.

Hi, how come there is a SSDT-PMC.aml file in the ACPI folder of the EFI? Dortania's guide says this is not required by 10th gen motherboards like z490i?

Also have you had any luck with Big Sur on this motherboard?

cheers

Haven't tried BigSur yet.. may wait someone who has the Z490i EFI folder ready for plug and play.

I'm on Big Sur 11.0.1 with no SSDT-PMC.aml. EFI attached.

any one tried to update to Big Sur with any success? Might won't boot the Big Sur but I can still boot back to Catalina.
