Hi there,

I've read several posts that state whatevergreen and RadeonDeinit aren't needed but I can't boot to the login screen without weg kext. The monitor states that it lost video signal. Any ideas.

That level of compatibility seems to be coming for some cards (including RX 570) in 10.13.4 (see <https://egpu.io/external-gpu-macos-10-13-4-update/>). As of now I think that only works for a very few RX 580 cards.

Thanks for the info. I have 10.13.4 beta installed and was hoping to test the native support.

Sapphire should work A-OK.

It's always XFX that has an issue, but you can always flash the card under Windows to a similar Sapphire model to make it work better.

update to 10.13.4 beta4 (17E170c), gets black screen on HDMI port. Only get back the screen using DVI port. Other than that, works fine in the new beta. I am using RX 560 card.Support natively without any kext added.
But, anyone know why it is black screen in HDMI port?

Throw in the nVidiaGraphicFixup.kext into your efi/other. That should fix the black screen issue.

I'm sure there's a cleaner way to do this, but that kext always helped me even with AMD cards.

It does not solve the problem in my case. Thanks away.

What SMBIOS are you using?

You should try 18,3 which is closes to the RX5xx

Keep nVidiaGraphicFixup in there before you switch to 18,3 because it's an alternate to AGDPfix (which modifies system files). We don't want to modify system files.

I had an RX560 in an 18,3 Skylake machine and it worked perfectly with multi monitors (including HDMI)

My card will not show the login screen (no signal) if whatever green is removed and or inject ati is checked.

I have changed to 18,3 but still get the black screen.
My card is Sapphire Pulse RX 560. I don't know whether different brands of card affect the situation.
Thanks anyway for offering helps.
