Home - Switch appears on my Login screen I need to know what to do because I was looking at accessibility settings today and now the log in screen has this on it: 



Is this called a prompt? I was trying to learn the VO modifier commands and I was looking at Trackpad commander. I'm not sure what to do about this, or what has happened here.

How do I remove it?
What you have there is called the Home Panel.

To disable it you can:


Go to Apple menu () > System Preferences
Click the Accessibility pane
Select Switch Control from the list of accessibility options (it's usually at the bottom)
Click the General tab
Untick the Enable Switch Control checkbox


For more information on this feature, refer to Use Switch Control to interact with your Mac on Apple's website.
