Chapter 6 Setting Up the Network and Maintaining Security 73
 Wireless networks also are not suited for multicast traffic. However Apple Remote
Desktop’s multi-observe feature is different because it doesn’t use multicast traffic.
 Display shared screens in black and white rather than in color.
 Configure your AirPort Base Station with a station density of High and increase the
multicast rate to 11 Mbps using AirPort Admin Utility. Using the base station density
and multicast rate settings limits the range of each AirPort Base Station’s network,
requiring client computers to be fewer than 50 meters from a base station.
Getting the Best Performance
To get the best performance when using the Share Screen, Observe, and Control
commands:
 Use the fastest network possible. This means favoring Ethernet over AirPort,
1000Base-T over 100Base-T, and 100Base-T over 10Base-T.
 If you’re using AirPort, adjust the multicast speed higher.
 Don’t mix network speeds if possible.
 Reduce the use of animation on remote computers. For example, you can simplify
Dock preference settings by turning off animation, automatic hiding and showing,
and magnification effects.
 View the client’s screen in a smaller window when using the “fit to window” option.
 View the client’s screen with fewer colors.
 Use a solid color for the desktop of the screen you’re sharing.
 Share screens only on local networks. If you share a screen with a computer
connected across a router, screen updates happen more slowly.
 Set the Control and Observe image quality to the lowest acceptable for the given
circumstance.
Maintaining Security
Remote Desktop can be a powerful tool for teaching, demonstrating, and performing
maintenance tasks. For convenience, the administrator name and password used to
access Remote Desktop can be stored in a keychain or can be required to be typed
each time you open the application. However, the administrator name and password
for each client computer are stored in the administrator’s preferences and are strongly
encrypted.
