Not authorised to send Apple events ... Mojave issue

[anbanpillay]

In the Mojave, cannot grab link. Error is "Not authorised to send Apple events to ...". Is there a workaround?

I don't know. I haven't upgraded. I guess maybe Emacs's do-applescript simply doesn't work on Mojave, if it's true, this is probably an Emacs issue.

I have upgraded to macOS Mojave and the error message I get is

AppleScript error 1

Below is the version of my Emacs

(emacs-version)
;; =>
"GNU Emacs 27.0.50 (build 11, x86_64-apple-darwin18.0.0, NS appkit-1671.00 Version 10.14 (Build 18A391))
 of 2018-10-23"

Anyway, this is probably a bug of Emacs. According to https://www.felix-schwarz.org/blog/2018/06/apple-event-sandboxing-in-macos-mojave

apps can no longer send Apple Events to other apps without user authorization.

Emacs now has to ask user for authorization, like Terminal.app

I just learnt the fix and it works here. Add the following to Emacs's Info.plist and restart Emacs.

<key>NSAppleEventsUsageDescription</key>
<string>Emacs requires permission to send some event to another application.</string>

The path to Info.plist for me is

(expand-file-name "../Info.plist" invocation-directory)
;; => "/Users/xcy/src/emacs/nextstep/Emacs.app/Contents/Info.plist"

Great. Thanks for your assistance.
Upgrading my emacs through brew to HEAD-c9487b2 seems to have fixed the issue. grab-link works now - a dialog pops up asking for permission and then all is well.
