The Finder Get Info Sharing & Permissions doesn't seem to allow adding x permission to anything, just read only, write only, or read & write. In any case, user _mysql does not appear among the users to add that way.
The chmod man entry for ACL manipulations is hard to penetrate.
With my mysql datadir in
and that matador already owned my _mysql, is the following what I should do?
chmod +a "_mysql allow execute" /Volumes/MacHD/Users/thisuser/Databases/mysql
chmod +a "_mysql allow execute" /Volumes/MacHD/Users/thisuser/Databases
(/Volumes/MacHD/Users/thisuser already has +x permission for all).

> You can use ACLs to only grant that permission to the _mysql user (see ACL MANIPULATION OPTIONS in `man chmod`, or use Get Info in the Finder and see the "Sharing and Permissions" section at the bottom of the info pane). But in general granting directory search permission is common and not considered to be a significant security issue. In particular, by default everything up to /Volumes/MacHD/Users/$USER will generally have a+x.
