    MP 1,1-5,1 MacVidCards Europe Radeon RX 6800/RX 6600XT for Mac Pro 4,1/5,1 benchmarks

    Radeon RX6800 16 GB is now the fastest card for Mac Pro 4,1/5,1 with standard EFI boot screen. You can see EFI boot screen even without any HDD/SSD installed at all. macOS Monterey 12.2.1 works natively without any patches. You just need to either move Monterey from supported Mac or install it...

    MP 1,1-5,1 MacVidCards alternative, or how to DIY EFI for RX580 Reference?

    Hey, I've dealt with Dave from MacVidCards a bunch of times, first with an HD6870, then a GTX760, then a GTX970... Every one of those times was fantastic, albeit, he was getting harder and harder to get a hold of, over time. Now, I sent an email 8 months ago, which he still seemed great...

    MP 1,1-5,1 Displayports not working on 1080TI with Mac Pro 5,1
