Did Apple remove the "AppleScript handler" option in macOS High Sierra? I wanted to make a little script involving messages on my Mac and after some research I discovered it was indeed possible. The only problem is that the "AppleScript handler" option in Messages>Preferences>General is missing for me. This very option is listed right on the Apple website under the High Sierra heading.

This is what I'm expecting:



But this is all I see:



For what it's worth I'm running 10.13.4 Beta (17E160e). Is it possible that this feature has been removed?
Yes, Apple DID remove that feature in 10.13.4. I actually opened a case on this with Apple Support (I even referenced this page) and they got back to me today and informed me that it really has been removed from Messages.  The Apple representative suggested going to http://www.apple.com/feedback/ if I wanted to express my displeasure, but that was all he could do.
