WindowSender: Sender is prohibited from synthesizing events (M1, macOS 12.6)

Open jcrm1 opened this issue 3 years ago • 1 comments

Problem:

  • I can see that my input is registering correctly in the Testing tab of the preference pane, but my mouse does not move and applications do not show tablet input.
  • I have removed and reinstalled the preference pane several times, and I made sure TabletMagicDaemon had Accessibility permission each time.
  • The first time I tried this, it worked, for the most part. The mouse moved, but applications did not detect a tablet specifically.

Error in Console.app:

  • Process: WindowServer
  • Message: Sender is prohibited from synthesizing events
  • This message is constantly repeated when the pen is engaged.

I am on macOS 12.6.

Since macOS is much more thorough about security, it's probable that the daemon is not running at the correct privilege level. If the Security panel in System Preferences doesn't show an option to give authorization to the daemon, then we'd have to dig into the current security APIs and make sure everything is being signed and authorized correctly, and with the right security / usage flags set in the info file.
