A veces no podemos reactivar los permisos de una aplicación reinstalada. Cada una tendrá su truco concrecreto de las cosas que habría que resetear, pero este es el caso de Bartender, que seguramente se podría extrapolar a otros:

```
tccutil reset Accessibility com.surteesstudios.Bartender; tccutil reset ScreenCapture com.surteesstudios.Bartender; 
tccutil reset Accessibility com.surteesstudios.Bartender-setapp; tccutil reset ScreenCapture com.surteesstudios.Bartender-setapp
