But make sure your MBP supports it. A pre-retina MBP is really outdated for this powerful software. My 2012 MBP is already borderline outdates - I'm just waiting for the new Mac Pro to be released to upgrade.
Alas, DVR (DaVinci Resolve?) simply does not start, so I'm left with a lonely Apple crash dialog. I am however in:
- Code: Select all
/Library/Application\ Support/Blackmagic\ Design/DaVinci\ Resolve/logs
and I see

davinci_resolve.log
with the following block of text toward the bottom:

Given this, it seems OpenCL is being used.
I think I've found the issue although I'm not sure where this leads from here. More investigation is needed. In the aforementioned directory, parsing through

================================
This application failed to start because it could not find or load the Qt platform plugin "cocoa".
Reinstalling the application may fix this problem.
The Cocoa API is quite vital to macOS, so now I'm going to attempt to satisfy this and determine why it happened. I have some guesses, but I'll refrain until I've exhausted some before I post back. Thanks for staying with me!
