I have googled all day long and I cannot get my new Decklink 12G Extreme 4K card to accurately display anything in Resolve 18.0.6-18.1. I have a flashed 4,1>5,1 unsupported 2009 Mac Pro (Yes, time to upgrade, but...) and managed to comfortably stay in Big Sur 11.6.4 until today. Tried rebooting in Recovery mode, attempted "csrutil disable" and the response was failure; Tried Cmd-S-R "Single user Recovery" and still no go with "csrutil disable". Since I'm using an aging unsupported Mac, I had to use OpenCore for my EFI and bless the system to allow for incremental updates, but no full sys updates, which means, no Monterey (yet) nor Ventura (without a serious hardware investment).
I can install Desktop Video 12.1, restart, bless Apple's security permissions, and get the Control Panel pane to launch and config. But when it comes to actually launching Resolve (Why else would I be here?!?) , v18.1 wants the latest updated drivers, which means installing 12.2 or 12.4, and after that, the OS no longer sees the 12G card. I must have done this 10x over and over again today in slightly different configs, all of which refuses to produce an image on any screen for that matter.
Watched this 10x and still cannot bless the security settings no matter what.
I am convinced it's an issue with an OpenCore patch for this machine, but I am also petrified of switching gears midstream in a project without 3x backup options before I burn another day dicking around with it.
Anyone else in this boat?
Please.. help!
