 > Introducing the simplest app on the market that has the sole purpose of moving your mouse pointer at regular intervals so that your machine never sleeps! And best of all, it works **ONLY** when you are not working, so be rest assured that the mouse won't start moving on its own without the machine actually being idle.
 
 
+## Error while moving the app
 
+In case you get an error from the app saying `mouse pointer cannot be moved.`, you need to give the app permission to control your mouse. Don't worry, it's nothing sinister, but Mac doesn't allow outside apps to gain accessibility to the mouse by default (which include Firefox, Discord etc.)
+
+In order to resolve this error you need to:
+
+Go to Security & Privacy -> Privacy -> Accessibility and allow the `amm` app to gain access.
