Why does drag & drop of emails not work under macOS Mojave or Catalina?

This article has been machine translated. If you find any errors, we would be grateful if you could report them to translation@timesensor.com.

If you perform a drag & drop operation from Apple Mail or Outlook to tSL, tSL instructs the email client to export the selected email to a temporary directory. This operation is performed by Apple Events.

New operating systems from macOS Mojave onwards are not very enthusiastic about one application controlling another via Apple Events. Therefore, the operating systems block this operation as a matter of principle and thus the drag & drop does not work.

To get the operating system to ask the user for permission to execute the Apple Event (which then saves this in the system settings), the key NSAppleEventsUsageDescription must be present in the package of the timeSensor.app or timeSensor Client.app.

Procedure:
  1. Open the app with a right click
  2. In Contents, copy the info.plist document to the desktop.
  3. Open the info.plist (this is an XML file that can also be opened with Textedit, etc.).
  4. Search for NSAppleEventsUsageDescription
If not available, the app should be freshly installed with the installer.
