Not All that Flickers is Gold -- There have recently been numerous reports of video flickering and color distortion in 5200-series Performas and LCs - particularly distressing to owners because the built-in monitors can't be detached for service. Symptoms include shifts between color tints that last anywhere from a fraction of a second to several minutes. The problem appears to be related to the 5200 analog board and may be more prevalent in earlier units, although Apple hasn't confirmed this information. Users experiencing problems should contact their Apple dealers or call 800/SOS-APPL. [GD]
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
