How to mute accessibility options voice over? Sometimes when I double click the power button, I hear a voiceover for accessibility options.
How do I disable this and all other potential voiceovers?
A triple-click on the power button will show the accessibility shortcuts window. In macOS Catalina, you can disable this in System Preferences → Accessibility → Shortcut (at the bottom of the sidebar list) by disabling all the checkboxes in the list. Prior to macOS Catalina it is not possible to disable this action.
