Rogue Amoeba continues to extend the wireless reach of audio with Airfoil 4.5, a major update to its popular wireless audio distribution utility. Most notably, Airfoil 4.5 adds full support for third-party AirPlay devices, enabling you to send audio to any AirPlay-enabled speakers or devices. AirPlay support has also worked its way into the free Airfoil Speakers extra, enabling Airfoil Speakers to receive audio from iTunes and iOS apps, along with Radium on Mac OS X. Also new in Airfoil Speakers is the capability to control playback in several new sources like Spotify, Rdio, and Radium. Airfoil 4.5 introduces support for Mac OS X Lion, opts out of ClickToFlash, and provides a number of bug fixes and performance enhancements. ($25 new, free update, 12.6 MB, release notes)
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.
