Thanks Nik, but your post today indicates that Nitro “supports” Finder tags in Tahoe. Have you posted any clarification on that? The cataloging software (Photo Supreme) writes finder tags as a synchronization option. I suppose the issue you described with changing those tags outside of Nitro or other PHOTO software could be an issue, but I simply see it as a “one way street” in terms of writing finder tags. The photo software doesn’t need to read or import them…but the option exits in the Finder to do a Spotlight search if one discontinues using a certain commercially branded photo software.
My case in point is moving away from Lightroom (a few years back) left me with a hierarchical keyword mess that took hours to untangle with other software (Photo Mechanic). Having finder tags would be a nice backup.
