BusyMac has released an update to its calendaring app, BusyCal 1.6.2, and while the list of fixes is small, they could prove important to many users. This new release corrects a bug that caused conflicts when syncing with Google Calendar, as well as another that prevented meetings from getting updated in iCloud. Additionally, it corrects an incompatibility with alarms that have no sound on Lion iCal Server. Localization changes round out the update. ($49.99 new, free update, 6.7 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.
