it is compatible
if your are running Mojave you can add a volume for catalina so you can get it working before you
replace Mojave with it. A nice feature of the APFS file system
update any kexts you use either by searching for them (most on github) or using Hackintool
Also update clover to latest release versions higher than 5000 will change EFI driver location
Three recommended Kext are Lilu, AppleALC, and WhateverGreen
Note Whatevergreen will need to be disabled if you install 10.15.1 beta 2 (19B77a) it causing black screen on RX 580 and 5700 GPU so far
