Power Macintosh Easter Egg -- Mike Basham <firstname.lastname@example.org> has reported the first Easter Egg for the Power Macintoshes. First, make sure no debugger is loaded. Hold down the interrupt switch while turning on the Power Mac, and then let up. The Power Mac will crash, accompanied by some, shall we say, realistic sound effects, complete with breaking glass.
View Extra Bluetooth Details in Snow Leopard
In Snow Leopard, Option-click the Bluetooth icon in the menu bar to view a few additional items in the Bluetooth menu. Specifically, it enables you to open three utility applications: Bluetooth Explorer, Bluetooth Diagnostic Utility, and PacketLogger. These are likely of interest primarily to experts, but if you're having troubles with Bluetooth, the Bluetooth Diagnostic Utility in particular may be useful. (These tools are available only if you've installed Apple's Developer Tools.)
