Yes, my RX480 is now recognized as 0x67df vendor id#1002. Last night on the last Sierra beta 2 it worked.
And, clover V3670 recognizes RX480 in Graphics injector and gives it the id # for you. Pretty sweet.
Something changed so the Nvidia webdrivers no longer works, at least on my 970, booting with nv_disable is all I can do for now
Where do i get 3670? I can only find 3650 at the site.
If you use the Nvidia web drivers then it is normal for them to break when an update changes the build number.
There will be new web drivers soon.
