Hey guys,

Just updated to the latest version of MacOS on my Mac Pro 4,1->5,1 and it cannot detect any graphic cards... I have 2 XFX RX 480's @ 8GB installed and the cards are no longer listed in the System Report. When I check out the PCI tab in System Report I get the message "There was an error while gathering PCI device information." The cards worked great on before the update; MacOS 10.12.3. I am currently controlling my Mac Pro via Screen Sharing from my MacBook. I have reset the PRAM but no luck. Can you guys please help me out?

Fixed! Things have changed as of MacOS 10.12.4 with regards to patching these cards. Luckily The IT Sage made a great revision to his already great guid: Link to guide

Here is LuxMark score with the latest driver patch
