Unlocking a Computer Screen
You must use Apple Remote Desktop to unlock any computer screen locked by
Remote Desktop. When you unlock a computer screen, you restore the desktop and
use of the mouse and keyboard on that computer.
To unlock a computer screen:

2 Select one or more computers from the list with a “Locked Screen” status.
3 Choose Interact > Unlock Screen.
4 Click Unlock Screen.
Disabling a Computer Screen
Sometimes you may want to control a client computer with a user at the client
computer, but you don’t want the user to see what you’re doing. In such a case, you
can disable the client computers screen while preserving your own view of the client
computer. This is a special control mode referred to as “curtain mode.” You can change
what’s “behind the curtain” and reveal it when the mode is toggled back to the
standard control mode.
This feature works only on client computers with Mac OS X v10.4 or later.
WARNING: Don’t log out a user or use fast user switching while using curtain mode.
These actions prevent further remote access to the computer and require the
computer to be restarted.
To disable a computer screen while you work:
1 Control a client computer.
For information, see “Controlling Apple Remote Desktop Clients” on page 88 and
“Controlling VNC Servers” on page 91.
2 Click the Lock Computer Screen While You Control button in the control window toolbar.
Alternatively, if you’re not currently in a Control window and have added the “Control
Computer in Curtain Mode” button to your toolbar, click that toolbar icon. You can also
select Interact > Curtain.
