Today, I was working on an .scpt file in Script Editor.app, when, suddenly, Script Editor would not allow me to save the file. It was a seemingly random occurrence; I had not done something unique when the error surfaced. I had successfully saved this file in Script Editor dozens of times today.
I then Quit Script Editor and double-clicked on the .scpt file in Finder, to open the file in Script Editor (which is my default application for .scpt files).
Script Editor responded with the following error dialog:
The document "My script.scpt" could not be opened.
I can launch Script Editor and I can create a New Document. But, I cannot open an existing document.
What I've tried:
Restarting and shutting down the computer
Running "First Aid' in Disk Utility.app
Opening Script Editor.app via the right-click context menu in Finder
Opening a .scpt file via the menu bar in Script Editor (File → Open...)
Opening a .scpt file via the right-click context menu in Finder
Creating a new document in Script Editor that contains zero characters. I can successfully save new documents in Script Editor, so I saved this .scpt file to my Desktop. But, after I closed the document window, I could not open the document in Script Editor.
All of my .scpt files originated in (i.e., were created by) Script Editor.
It may be important to note that I could open the .scpt files in TextWrangler.app and Atom.app.
Here is the Sharing & Permissions pane for the app file (via Get Info window in Finder):
These two questions are similar to my own:
However, the solutions do not apply to my scenario.
Short of re-installing the OS, is there anything that I can do to get Script Editor up and running again?
OS X El Capitan, version 10.11.6.
