Final Cut Pro applies .cube LUTs through its built-in Custom LUT effect — no plugin, no conversion. The 12-LUT pack drops onto any clip and you dial it to taste in the inspector. Free, no email.

Final Cut has a separate Camera LUT setting (in the info inspector) that converts log footage to Rec. 709. If your clip is log, let the Camera LUT handle the conversion, then add the creative Custom LUT on top. Stacking two conversion LUTs is the most common reason a grade looks crushed or oversaturated in FCP.
On already-standard (non-log) footage, skip the Camera LUT entirely and just use the Custom LUT effect.

To grade a whole sequence, drop your clips into a compound clip (select them, then Option-G) and apply the Custom LUT to the compound — every clip inside inherits it, and one Mix slider controls the lot. Keep individual exposure fixes on the original clips before you compound them.
Prefer to keep clips separate? Grade one, then copy it and use Paste Attributes (Command-Shift-V) to apply the effect to the rest — just note the Mix won't adapt to differently-exposed shots.

Vivid Teal and Cinematic for crisp, contemporary color.
Faded Film for faded, filmic character.
Add the Custom LUT effect to your clip, then in the inspector open the LUT dropdown → Add Custom LUT and choose a .cube file. Lower the Mix slider to set strength. No plugin required.
You're probably stacking two conversions. Let Final Cut's Camera LUT (info inspector) convert log to Rec. 709, then add the creative Custom LUT on top — don't apply two conversion LUTs at once.
Put your clips in a compound clip (Option-G) and apply the Custom LUT to the compound. Every clip inherits it and one Mix slider controls all of them.
