Rogue Amoeba’s Fission audio editing software gets a minor update with version 2.1.1, which offers a lone feature addition: the Batch Converter now accepts folders containing audio files as well as individual files. The release also ensures that the Save panel remembers the last saved location, corrects an issue with chapterized AACs and very large image files, and fixes an issue with the Mac App Store version where attempting to save a file would cause an error. Additionally, Fission now includes a hidden preference accessed via the Debugging window that enables the app to check for and prevent rare instances of Normalization clipping.

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.
