The maximum price of an App Store app is $999.99, and yes, some cost that much. Mike Wehner, writing for TUAW, reveals that some of those expensive apps are an elaborate scam to rig App Store rankings. The scam works by bumping up an app’s price to $999.99, having a second party buy multiple copies — which moves the app near the head of the Top Grossing list — and then, with the increased attention, lowering the app’s price to a reasonable figure and raking in the sales. But other developers, like Sergiy Grachov, who sells his Fleas game for $999.99, do it simply because users keep buying. follow link
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.
