Hear changes in progress or status
By default, VoiceOver announces when the progress bar or status text in the VoiceOver cursor changes. For example, while installing software, you might hear “Installation 45 percent completed” or you might hear a ticking sound.
Note: VO represents the VoiceOver modifier.
You can change the options for status text while you work using the rotor.
To open the Verbosity rotor, press VO-V.
Press the Left Arrow or Right Arrow key until you hear “when status changes” and the current setting.
Press the Up Arrow or Down Arrow key until you hear the setting you want.
To close the rotor, press the Escape key or Fn-Tab.
You can choose how the changes are announced, or turn them off, in the Announcements pane of the Verbosity category in VoiceOver Utility.
If you’re using portable preferences on a guest computer when you change status settings, the settings are saved to the portable preferences drive and not to the guest computer.
