New document that provides an introduction to using AppleScript and JavaScript to streamline workflows and increase productivity in OS X.
I wonder if this is part of the documents for macOS Sierra, and if there have been any changes since El Capitan?
I’ve only looked at a bit of it, but it’s the same document as before. There have been some changes – ASCII character
