Apple Studio Display (ADC): Pressing Button Does Not Open System Preferences

Symptom

Pressing the button on the lower left of the front of the Apple Studio Display (ADC) does not open the Displays pane of the System Preferences application.


Solution

Follow these steps to open the Displays pane of System Preferences:

1. Choose System Preferences from the Apple menu.
2. Click Displays to open that pane within the System Preferences window.

After closing System Preferences, pressing the button opens the Displays pane of System Preferences. However, pressing it again does not close System Preferences.

The symptom described above will recur if you log out or shut down the computer. A future Mac OS X update may provide the button with full and persistent functionality.
