After I updated to Mojave, I can't no longer use the automator service I've previously been using with the alert below.

• In Security & Privacy, I already checked AppleScript Editor.

Do you see any problem with my code or is this the problem of the newest macOS?

Script

on run {input, parameters}

set pathList to {}

repeat with itemNum from 1 to count of input

    tell application "System Events"

        copy POSIX path of (container of (item itemNum of input)) to end of pathList

    end tell

end repeat

return pathList

end run

This is definitely a part of Mojave's new security framework. In terminal try

osascript -e 'tell application "Finder"' -e 'set _b to bounds of window of desktop' -e 'end tell'

and you may receive:

36:42: execution error: Not authorized to send Apple events to Finder. (-1743)

What is supposed to happen on the first execution is the Finder opens a dialog box informing you that terminal is requesting permission to send events to the Finder. If you allow it, then terminal will get added to the Automation page in System Preferences > Security & Privacy > Automation:

There's two issues that I see at the moment:

• the implementation of requesting permission for the scripting action appears to be bugged; I've run other scripts that request permission to send events to Safari and the Finder doesn't prompt for permission, it just returns an error.


• streamlined automation requires some type of mechanism to have the permissions granted a priori; an example would be utilizing AppleScript with Ansible and being unable to preload grants

Others have written up more extensive information about this:

• https://forums.developer.apple.com/thread/106949

Hopefully this gets worked out before Mojave ships as it seriously impacts automation capabilities on macOS.

I had a similar error running AppleScript .app applications. I received the following error:

Not authorized to send Apple events to Finder. (-1743)

A workaround is to re-export the Application from the .scpt or .applescript source code. This generates a new .app application, which in my case ran successfully. The initial launch required approval (as well as some subsequent launches), and the application was added as an entry under Settings -> Security & Privacy -> Privacy -> Automation.

UPDATE: Updating to the latest Public Beta (as of 4 August 2018) fixed the issue for me. Prior to this, the issue did persist in all public betas of Mojave.

Original reply:

Just wanted to let you know that both myself and another friend are experiencing this exact same problem, with different Automator workflows that use Applescript (different than yours). We have the problem occurring with both manual activation (Finder --> Services --> click item) and with keyboard shortcut activation.

Even stranger, the workflow performs beautifully when testing inside Automator.

I've filed a bug report through the Feedback Assistant, and suggest to anyone else who sees this that you do too! Squeaky wheel and all...

Automator - Permissions error. "The action “Run AppleScript” encountered an error: “Not authorized to send Apple events to System Events.”"

Automator workflow performing well inside Automator

Here is what I did that resolved the issue for me. I went to System Preferences > Security & Privacy > Accessibility (Options on left hand side) > (Enter system password) > Click Automator (or your app you want to enable) and TADA it works.

I faced same error opening gitk.

Error in startup script: execution error: Not authorised to
send Apple events to System Events. (-1743)

SOLUTION

Goto Settings -> Security & Privacy -> Privacy -> Automation -> Privacy tab and check the System Events checkbox.
