moving files 27" Mac to a iMac Studio

Try this:

Quit FCP.

Select the library in the Finder, control-click, Show Package Contents.

Press Command-Shift-period to show hidden files.

You should see a folder .lock-dir and two files .lock and .lock-info

Drag the three to the trash. Don't change anything else inside the library.

Close

Double-click to open in FCP.

Does it work now?

I did that and the 3 files are not active ( faint image)

They are not "inactive" - any file whose name starts with a period is a hidden file.

When forced to show hidden files, Finder displays them like this, to indicate that they are hidden.

That is perfectly normal.

The idea is to delete these files in the hopes that FCP will then open the library.

I can't delete them

Again: what happens?

Do they show with a forbidden sign?

Are you dragging them the trash? And then what? ... details, please. Just "I can't" is not clear enough.

NO I can't delete the files?

Sorry, our posts crossed.

What happens if you try to delete them?

Do they jump back to their location? Or do you mean that they are deleted, but afterwards the problem remains?
