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]
Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
