I m currently running el capitan 10 13 6.
Sapphire pulse rx 580 mac pro.
Gpus were installed in x16 slot one.
This is due to it being used in the official external graphics dev kit.
I have a 2009 5 1 mac pro and want to get it working with mojave.
I have tried the vega 56 and now the sapphire nitro rx 580.
The sapphire rx 580 pulse 8gb is the only current generation amd gpu identified correctly in macos.
I have a 2009 mac pro 5 1 and upgrade cpus running os x 10 13 6.
I wanted to upgrade my video card.
2010 mac pro tower with 3 33ghz 12 core xeon x5680 with 96gb of 1333mhz ddr3 ecc sdram running macos mojave 10 14 6.
Hi thanks in advance for any help.
When i tried the vega it booted fine but no video.
The sapphire pulse radeon rx 580 is also one of the recommended models for use as an egpu with macos 10 13 4 or later.
Using both aux power ports.
