OK, this feels like an idiot question, but I'm stuck - I don't know the first thing about AppleScript. I have a .scpt file and I want to double-click it and just have it run, but instead every time I click, it opens up the AppleScript Editor. This feels like it should just be an option on the file, but I'm missing something obvious.
Please help me feel less dumb, thank you.
Answer
From the “File” menu, choose “Export”; there’ll be a “File Format” dropdown underneath the file browser. To get a double-clickable application instead of a document, choose “Application”. This will produce a .app bundle like ordinary Mac applications (this will also let you package other resources with your script if you need to). You can choose “Run Only” or not; if you do, then anybody with just the .app won’t be able to edit your script further, since it’ll be compiled. (But if you’re saving a copy as the application, that might be what you want.)
Another option, as per an anonymous user on Ask Different, would be to save/export your file as a “Script” (.scpt) or “Script Bundle” (.scptd), save it in ~/Library/Scripts/, and check “Show Script menu in menu bar” in Script Editor’s preferences.
