Nothing more to add to this at this moment. It is interesting that Apple has added non existing GPU kexts into the system. 2 GPUs may come: Polaris 12, and refreshed Polaris architecture. It would be baffling if the benchmarked GPU was Polaris 12. And BTW. This framebuffer is linked to Trash Can Mac Pro. So somebody is at least testing hardware. macOS Sierra 10.12.2 Beta 5. https://www.tonymacx86.com/threads/...d-radeon-drivers.197273/page-118#post-1386344 And no, this is NOT fake.
