@casey: Do u know some trick to get sound transferred by HDMI or DisplayPort? With Audio Port 7 my Case ports are working and with Port 11 my Mainport Ports. But I don't want extra cabling .

You have to select System Preferences > Sound > Output -

I must say this is a great guide, I cannot thank you enough. I've just built this up but used a 9900K instead. Everything was/is working wonderfully. However, I've discovered an issue with booting straight to a 4K screen.

I initially did the whole setup at home with a 1080p screen. Everything was great.

However, I've just taken the unit to work and tried to boot it onto our 4K television, and there's no output once the OS loads.

1. You can see the motherboard POST
2. You then see the initial Apple logo and progress bar as it loads.
3. Then the screen flashes black, and it goes to a blank screen, and the display shows "No Signal".

If I plug in a 1080p monitor, then it loads fine and shows the login screen, but if I try it with a 4K display, I get "No Signal".

However, if I boot the machine with the 1080p monitor, as soon as I reach the login screen, I can connect the 4K display, and it sends a signal to the screen and mirrors the displays. I can then disconnect the 1080p screen, and macOS recognizes the change and displays on the 4K screen only. If I reboot in this config, I get the same initial "No Signal" error.

Some background info: I've tried this with a 4K ASUS screen, and a 4K Toshiba TV. I'm plugging straight into the GPU with an HDMI cable (for the TV) and straight into the GPU with a DP-to-DP cable (for the ASUS monitor). [Also the GPU is in SLOT2]

Any help would be greatly appreciated.

It's saying no output controls.

It's saying no output controls.

This is normal for most displays with built-in speakers because volume has to be adjusted on the monitor itself (activate the monitor's built-in menu and it should allow you to set volume level).

Hello CaseySJ, thanks a lot for the great guide! I want to build my first Hackintosh and i plan to follow your guide and instruction (with a Sapphire Radeon RX VEGA 64 8 GB NITRO+)
I just have a few questions:
1. Will Corsair Vengeance LPX 4000Mhz 32GB (16GBx2) be compatible? The Gigabyte MB is, but does it work with Mac OS?
2. Both the Broadcom WiFi and Bluetooth Module -- BCM94360CS2 and PCIe x1 adapter card for WiFi/BT module are out of order in all the shop in my country. Do you maybe have an idea to replace it? I have found this one here but i can't tell if this gonna be compatible with your guide.
3. i plan to buy a Samsung NVMe SSD and also some Samsung SATA SSD. Does the brand matter for your build?

Thanks to anybody who can reply to me

Very glad to see another successful build!

Let's see if we can troubleshoot this issue or at least find an acceptable workaround until a proper fix becomes available:

• Are you using an AMD RX 580 in Slot 2?
• You stated that if you boot the machine using an HDMI cable connected to a 4K Toshiba TV, you do get video output until the final seconds of the boot sequence when MacOS initializes the display driver. At this point, there's no 4K signal from the HDMI port. In this case, have you tried unplugging the HDMI cable and re-plugging it after a second or two?
  • I thought this happened only with the internal UHD 630 GPU, so I will test this myself later this evening.
  • But please try the hot-plug "workaround"...
• You also stated that if you boot the machine using a DisplayPort cable connected to a 4K ASUS monitor, the same problem occurs. Does the same hot-plug workaround work with DP?
• Finally, have you tried using HDMI output from the motherboard itself (after applying the framebuffer patch mentioned near the end of the build guide)? A new more effective version of the framebuffer patch for UHD630 is coming soon, probably tonight or tomorrow. (I am almost done with the testing.)

Thanks for the reply. Yes, I'm using a Sapphire X580 Pulse 8GB in slot 2.

I have tried unplugging and re-plugging both the HDMI, and the DP cables and this doesn't help. I have also tried plugging the HDMI cable into the mobo directly - this also doesn't help.

I had thought maybe it was an issue with the TV, but it also happens with the ASUS screen. Both the TV and screen have been used for a long time with genuine Mac mini's, etc with no issues.

I can also give a further update, moving on from my initial post. I have plugged in an LG 5K UltraFine display into the TB3 port (after running a DP-to-DP cables from the RX580 to the DP-in) and it runs this absolutely fine, and boots to it with no issues.

EDIT: I haven't done the Framebuffer patch at the moment.

This is the first confirmation of a 5K Thunderbolt 3 display working on this motherboard -- and out-of-the-box, no less! Thank you for posting that - it deserved its own reply.

@AlexD might be interested to know this.

This is a longshot, but worth trying...

Because you're using a Sapphire card, please try setting Framebuffer to Orinoco in Clover Configurator --> Graphics.

If anyone here has a Sapphire RX 580 and a 4K monitor, do you also get a black screen when booting to a 4K display?

I'll check my MSI Gaming RX 580 later this evening.
