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

[CaseySJ]

I have the exact same problem with my Radeon VII as do others I've seen post here, so it doesn't seem likely to be related to defective cards. My RVII doesn't experience any instability when under load in games in Windows or in GPU compute tasks in Blender either.

It's strange because it only happens in 1 out of 5 boots and it's completely random when it happens. I figured it might be Lilu/WEG in combination with Apple's immature drivers, but couldn't say for sure.

FWIW I'm running mine from an EVGA G3 750W with both PCI-E power cables attached.

I see. Does enabling CSM Support in BIOS make any difference? Did it happen in 10.14.4?

Ah I hadn't tried that, so I'll give that a go. I updated my post above too. Cheers for the help

I know the first batch of Radeon VII cards stupidly didn't support UEFI out-of-the-box, but my firmware version is only dated March 2019, so it should've been fixed already. I currently boot Windows in UEFI mode with it too.

EDIT: Got the boot error 4 times in a row, so it doesn't seem CSM appears to affect it.

Perhaps you already have the answer but roughly:

1. In Bluetooth settings you can enable an item in your menubar -- do that
2. Click on that while holding down alt -- then scroll down to a connected device -- you should see a lot more details including single level. Roughly speaking:
   1. anything bigger than -50 is pretty great
   2. -50 to -75 is serviceable
   3. less than -75 is pretty miserable (start to see disconnects)
   4. unusable at -90
   5. Note that the values tend to fluctuate quite a bit so you may need to read it a few times to get a sense

On my new Fenvi card, I still had poor Bluetooth power problems but when I turned off wifi (I'm hard wired) it worked much, much better. I'm honestly very confused about wifi and things like handoff and continuity. I've heard that you have to enable wifi for those features (which never made sense to me -- how would your computer know if it's a wifi connection or a wired connection?) but regardless -- after wifi off the Bluetooth worked great AND, as far as I can tell, all of my continuity features continued to work (but I didn't test it very thoroughly)

Fun Fact -- I'm sort of ' in the business' with regards to RF things -- the units the mac shows are in dBm which is dB relative to 1mw of power

dBm	Power (W)
-60	1 × 10^-9
-70	1 × 10^-10
-80	1 × 10^-11
-90	1 × 10^-12

The point of the fine table above is that when your mouse is working at -60dBm (which it will work just fine with) you are dealing with one Billionth of a watt of power -- that is not a lot of power!

Thanks for the info. I'll try switching wifi off. I think handoff needs wifi for phones and ipads etc. .......Now to to get a video doorbell that actually works is another matter!!

Hey Skittlebrau,

Aside from the bug you're trying to iron out, how is the Radeon VII playing in your build? I'd like something more powerful than the Vega 64 for when I'm gaming in Windows, but stability in macOS for productivity is a must.

I can't figure out why I have short range cordless communication (both BT and RF).

If I move keyboards away from the case more than 50cm, they start to loose keystrokes.

All this stuff (Logitech K380 BT and K270 RF + Broadcom BT card) used to work fine on my previous build with Mojave 10.14.3 and MSI B250.


Any Suggestions?!?
@CaseySJ
Thank you.

Please try the attached config.plist. If you'll be selling the RX 580 and using the iGPU exclusively, it's good to have all 3 on-board video ports enabled (the two Thunderbolt/DisplayPorts work by default). The attached file will do that.

In BIOS, set Initial Display Output to IGFX.

Terrific Casey; you're config.plist worked to get the UHD630 iGPU going on my board; but I notice a considerable less view quality output via the onboard UHD DP output to the same monitor. I think it is better to keep my MSI RX580 for that matter. I have put back the previous config.plist. Is it normal that the DP and HDMI outputs on the RX580 are not supported in Mojave ? Regards from Holland,

Sleep is no longer working . Can you help please?

If you go into activity monitor and right click on the task list to 'show processes preventing sleep' is there anything running? Intel Power Gadget is one thing that will prevent sleep...

That's a good idea, but instead of right-clicking, we need to select this:

Hello Bart,

DP and HDMI outputs on the RX 580 are absolutely supported in Mojave, and have been since the beginning. But the VBIOS on different makes and models can be different. It is often a good idea to run Hackintool and check this:

If you see "5" then mostly likely all ports will work. It is best to avoid video converters and use straight HDMI-to-HDMI or DP-to-DP connections. (Video converters do work, but when you're troubleshooting a black screen problem it is best to avoid them.) It is also recommended to use monitors that support DisplayPort 1.2+ and/or HDMI 1.4 (ideally HDMI 2.0+).

Also, I'm curious about the considerably less view quality from the on-board Thunderbolt (DisplayPort) output. This supports 4K at 60Hz! With a USB-C to DisplayPort cable, did you see any visual artifacts or glitches? Or did the display seem to look worse subjectively? Is it possible to grab a screenshot?
