Converting 32-bit to 64-bit - AppleScripts

[odamizu]

For those of us fretting about our favorite 32-bit AppleScripts (including the one from Alf), here's how to convert them to 64-bit:

• Open AppleScript in Script Editor
• File > Export > File Format: Application > Save
  OR
  File > Duplicate > Save > File Format: Application
• Confirm by checking Get Info (Command-I). If there is an option to “Open in 32-bit mode”, that means the AppleScript has been successfully converted to 64-bit.

If the above fails, look for odd characters in the AppleScript name such as "/". Delete the problematic character. You can rename the AppleScript after it's converted to 64-bit.

To add custom icon:

• Open Get Info window for both old 32-bit and new 64-bit AppleScripts.
• Click on the desired icon in the upper left corner of the 32-bit app and copy.
• Click on the generic icon in the upper left corner of the 64-bit app and paste.

Note: This works for macOS High Sierra. It should also work with Mojave. Earlier versions may work differently or not work at all.

Finally, big to @pdurrant for guidance!

And it worked for me in El Capitan!

The only thing is that the 32-bit version Get Info has a check box labeled "Prevent App Nap" while in the new 64 bit version that box is replaced by the "Open in 32-bit Mode" check box.
