@Sleepy - There is indeed, but once I start browsing the apps folder all I see is the KM app itself not the Engine......
@tiffle - Right that seems pretty complex having to design a script to get the function added. None of my Macros seem like they need that functionality at the moment so I'll hold off trying to get rid of the error for the moment.
In Big Sur and later, you can actively add the Keyboard Maestro Engine to the Screen Recording permission in the System Preferences, Security & Privacy, Privacy, Screen Recording settings by unlocking the System Preferences, and then finding Keyboard Maestro.app in the Finder, control or right click on it, select Show Package Contents, drill down in to Contents, and then MacOS to find the Keyboard Maestro Engine.app, and then drag that in to the Screen Recording settings.
Not really complicated - just create a macro with one action in and then Try the action or run the macro, as it says in that thread I linked to and in the wiki:
“ If Keyboard Maestro Engine does not appear in the permissions, create a Screen Capture action and capture all screens, and “Try” the action or run the macro. This should force the system to notice and prompt you for permission.”
Maybe, but the only reason to do this is because of Apple’s buggy permissions, so I really don't want to. It is also more likely to lead to people messing up the application and leading to other support problems.
