[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[TheAsocial]

It might be a good idea to fully activate the UHD 630 ports. Whether this has an impact on the RX 580's ability to drive your HDMI TV is unclear, but it won't hurt and will rule out one additional factor.

The easy way to do this is simply copy and paste the settings below to your config.plist on the EFI partition of your Mojave disk as shown.

Just need to copy and paste the above code into this section:

<key>Devices</key>
<dict>
    <key>Audio</key>
    <dict>
        <key>Inject</key>
        <integer>7</integer>
        <key>ResetHDA</key>
        <true/>
    </dict>
    --- paste the Properties section right here between Audio and USB ---
    <key>USB</key>
    <dict>
        <key>FixOwnership</key>
        <true/>
        <key>Inject</key>
        <true/>
    </dict>
</dict>

After rebooting you can even try connecting the HDMI TV to the HDMI port on the motherboard itself...

OK, so that didn't go well. I'm not sure if I pasted the code into the config.plist correctly though.

The UHD630 wasn't recognised and my LG 5K wen't back to the strange half and half (2 displays recognised) issues from before.

I've attached by config.plist (with SN removed) if you could double check my workings?

Also, here is my config.plist before I made the change.

@TheAsocial I'm wondering if you had a chance to try connecting Apple Thunderbolt Display today? Really curious to see your experience with it.

 

[CaseySJ]

Also, here is my config.plist before I made the change.

Please try the attached config 2b.plist. The only suspicious settings were (a) ig-platform-id="0x0" instead of having it empty (in Graphics page of Clover Configurator) and (b) InjectIntel=true (which I set to false). The same problem exists in both config 2.plist and config 3.plist.

When we apply framebuffer settings via the Properties section, we should disable IntelGFX, InjectIntel, and ig-platform-id from the Devices and Graphics pages of Clover Configurator. That's because we want WhateverGreen to fully take over those functions. (We don't want Clover injecting any conflicting parameters.)

Update on Dual Monitors (LG 27UK650) I switched both to Display Port, driven off of my RX580 and it boots comes up to both with out issue.

Oh yea, I just edited my first Audio Project with it. I do a Podcast for a friend which involves editing, eq'ing and then compressing (the audio) then the files into MP3. This machine is way faster than my old one, and my 2016 MBPro. I did a little comparison and it is on par with an "entry level" iMacPro. With far more storage and RAM. Woo Hoo! Thanks again @CaseySJ and everyone else who helped. Especially the FCP crew.

My motto: When in doubt, use DisplayPort. It seems to be the least fussy of them all!

Hi guys,

I often have a disconnection of Thunderbolt 3 cables. in fact I can not find out if it comes from the hackintosh or the quality of the design in general Thunderbolt 3 / USB-C. if I have the misfortune to touch the connector, it disconnects. It's crazy. If I do not approach the computer, everything is fine. Did you meet this? Or you can safely touch the cable without problem?
I will end up believing that the design / manufacture of USB-C is really crap.
Thank you.

LOL, it was weird. When the monitors were dark (HDMI connected), I could see the second one in System Profiler. And I could log in using Chrome Remote Desktop (I HIGHLY recommend using this, it is available after boot and before logging in) if the main one was black. Now with DP all good! I am still using iMac18,3 in SMBIOS.

This happens with my MB Pro, If I bump the cable connected sometimes my drives drop out. I Ended up buying a couple $$ good cables and that helped. It seems to be my MB Pro connectors...
