They'll never back port it. Ever. An upgrade will be required.

Sierra 10.12.6, High Sierra 10.13.6, Mojave 10.14.6 all the final versions only security upgrades to follow. Catalina is the only option most likely.

I downloaded the latest 15.1 and there is no major change from the prior versions. This must be a mistake by Apple, maybe 15.1.2 will have it. I'm not even going to bother editing the info. plists of the kexts, as they don't show any Navi support (10000Controller and 5000kext).

Maybe the Device ID of the consumer RX 5700 series is not there, but I have not seen any RDNA based Vega II cards out there to know its Dev_ID and try an injection over the 5700 card. It would be worth trying IMHO - if only I had this card...

Looking into the drivers and the only ones with Navi are the same as the last beta version. There is still no ZN38 in the 10000controllerkext so Navi10 is not going to work there.

When we had partial support for the Polaris cards back in Sierra betas the device ID was in the 4000 kext but not the controllerkext and we could edit it into the controller and it worked. They may have just forgotten to include updated graphics Kexts and they may come out in the next update or a supplemental update.

Trying to fake the ID to a Vega card most likely won’t work either because they use HBM2 and the Navi cards have GDDR6 which has completely different controllers.

Do you think Apple just made a mistake, or there may not be support for 5700/5700 XT cards in the future macOS?

Yes, I think they are going to release the drivers but they made the announcement before they were ready. They have been working on them, it's just a matter of time.

You don’t know if Sapphire graphics cards are always supported on macOS if Apple guarantees support for certain chipsets?

Just someone on the forum wrote that some theoretically compatible video cards (from different manufacturers) with macOS refuse to work in a hackintosh.

Sapphire cards usually work, but their RX 590 Pulse didn’t, the Nitro version does.

It comes down to custom BIOS on the card. Usually reference cards all have the same AMD provided BIOS and then the custom fan cards come out and sometimes have incompatible BIOS XFX is known to have custom BIOS versions that restrict their use in macOS. But, not all XFX cards have the problem.
Sapphire, Powercolor, MSI, Gigabyte, and ASUS cards usually are compatible.

The Sapphire Radeon RX 5700 XT Pulse card just suits me in size and everything else. Then, I’ll probably wait until macOS comes with full Navi support and until someone buys such a card to report its performance in macOS.
