Any clue?Supermicro X8DTL-6F2 x Xeon X5650RX580 MSI I have Catalina running on my own Nehalem-based system. If you want to run Mojave as @Slice suggested, your system will run perfectly as MacPro5,1. If you want to run Catalina, it will still run perfectly with Clover bootflag -no_compat_check. My RX580 is working with the following configuration items: Configure CLOVER config.plist with the following options Fixes: FixDisplay Boot Arg: -no_compat_check (for Catalina) Graphics: Vendor ID: 0x1002, Product ID: 0x67DF, FB Name: Orinoco, Inject ATI, RadeonDeInit Lilu.kext and WhateverGreen.kext Add Fake EC if your DSDT doesn't have one (I think this was required for Catalina - not sure) Edited February 4, 2020 by tonyx86 Link to comment Share on other sites More sharing options...
