Joseph Schmitt, taking a cue from Federico Viticci of MacStories, has figured out a way to control a Mac with a Pebble smartwatch. Combining Keyboard Maestro for the Mac with Command-C for iPad, Schmitt demonstrates opening his frontmost Safari tab on his iPad. He has also figured out how to use his Pebble to pause or resume Backblaze backups, restart iTunes, and restart Hazel.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.
