Please refer to the latest DaVinci Resolve configuration guide for details on Mac OS X support, including certified driver versions for third party hardware. It is available from

Sadly, the "latest" configuration guide is from August of 2019. It suggests many computers that are no longer manufactured. I often have to recommend systems for people setting up Resolve workstations, and it's crazy that I have to essentially research this topic and find suitable currently-available hardware to spec, rather than just let the user read an up-to-date guide from Blackmagic. I realize this is low-priority, but maybe an annual update is possible? I really need one this afternoon!
