Concerning 'I would run Disk First Aid': I'm not quite sure
what 'locked' is and I don't understand much of the MacOS.
But in MCL (Macintosh Common Lisp) there's a function to
unlock files. I print here the documentation: 

"UNLOCK-FILE file [Function] unlocks file. If the file was
previously locked, it will now be unlocked, so that it can
be written to. If the file was already unlocked, no action
is taken."

_When_ there is such a function there must be a trap or
whatever in the MacOS. Can you ask a MacOS guru or take a
look of IM?
