Mac OS error code -1407
Summary:
Mac OS error code -1407.
Deleting a file from a hard drive can occasionally result in error code -1407. This error can be caused by a variety of sources, but the method to fix it is simple.
This error can mean a program has a file "Locked", but isn't reporting properly about it. Because of this, begin by closing all open programs, then try to delete the file again.
If that doesn't immediately solve the problem, eject the drive by clicking the eject button in a Finder window.
The eject button is the icon in the right side of the circled area. Unplug the drive from the computer when the entry disappears from the Finder window. Leave the drive disconnected for a few minutes, then reconnect it.
It should now allow the file to be deleted.
