Having downloaded the free version of Resolve 11 from the app store, I proceeded to try and export LUTs from it for import into Final Cut X. The program would not export the LUT; clicking the button produced no action. A call to Black Magic instructed me to remove the app store version and download the same software from their website, and their version was somehow more robust. Sure enough, they were right. Not sure if this will still hold true in 12, but do your research.
