1 tracks have not been updated probably due to a write permission issue

I get this message when I try to change the meta tags of files. In fact, the tags are already there and show up on iTunes, Vox and Amarra, but do not on Audirvana. It wouldn’t be a problem, but I am not being allowed to fix it.

The files for all players are in the same place and permissions for the whole drive are “ALL.”. This is a Mac running the latest operating system.
