In fact, after downloading the trial and giving permission in Accessibility to the Keyboard Maestro.app, I do not see the engine there nor do I see anything in /Applications/Keynote.app/Contents/MacOS. It seems to run if the application is running, though.
Used the tab key on the command line to accept the option when I typed K and Keynote was the only choice. I should have looked more closely
Keyboard Maestro does not appear in the /Applications folder nor in the ~/Applications folder. I logged into another account on the Mac and dowloaded the "Free Trial" and was able to start it however in this case nothing at all appeared in Accessibility.
I own Keyboard Maestro. Should I be retrieving it from someplace else?
Sometimes an app can be installed in a location other than the applications folder and you have to move it to the apps folder. At least when you download the DMG files. Is the app perhaps in your downloads folder or desktop? It’s been forever since I installed KM so I can’t remember what the install process is like.
You first said the KM Engine is missing. Later, you said the KM app is missing?
I think when I did something, the KM Engine was also missing in Accessibility. I was not able to add the KM Engine to the list, because the KM Engine is located inside the KM app folder. /Applications/Keyboard Maestro.app/Contents/MacOS/Keyboard Maestro Engine.app.
I solved it by running macros. KM Engine automatically pops up to require Accessibility access.
