Any updates on Color Finale and LUT Gallery Crashing FCPX?

I have used these two programs for months, but I miss having an organized library of LUTs and the ability to preview. Plus, I would like to be able to use my color checker passport. Is it safe to use again, and if not, can anyone recommend a different way to preview looks in FCPX?

I can't speak to to the passport because we don't use that, but Color Finale Pro and the LUT Gallery work fine. The latest version is 1.9.2 Build 258 and has been working for me for quite a while. Tested it just now with the latest FCPX 10.4.6. released today.

There are a few other LUT utilities, but we generally use mLUT (free by Motion VFX).
