Thanks for a pinch of hope.

But how it would be possible to spoof the ID, if 6600 is BigNavi 23 and 6700 is BigNavi 22? Or thay are not so diferent as BigNavi 22 and BigNavi 21 (6800&6900)?
When the RX 460 support came in Sierra we were able to use RX 480 cards but they ran on the 460 drivers and we had 14 CUs (compute units) instead of the 480s normal 36 CUs. They worked but they were not used to full capacity. Apple eventually released proper 480 drivers.
So it may be possible to use the lesser driver, however Apple has made the drivers tougher to spoof these days. It may also not work but only time will tell.

Did you look at the chart on the first page? It doesn’t seem to be working out of the box and the device id is listed as unknown.

I think that list is outdated because after searching this site I found posts where people had faked the device I’d and made it work. Check out this thread here:

Besides my HD 7850 works for macOS out of box and is recognised as R9 270.

I would assume it is the same as the other non ‘X’ branded cards, ie. it requires a fake-ID to work in macOS.
