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.

One quick recommendation for something else to read this week — a warning about Mac-focused Trojans that install ad-embedding extensions in Safari, Chrome, and Firefox.

Beware Trojans Bearing Ads -- According to Russian security firm Doctor Web, there are an increasing number of Mac-focused Trojans that install extensions for Safari, Chrome, and Firefox. These extensions are designed to embed third-party ad code into otherwise unrelated Web pages, funneling the clickthrough revenue back to the malware authors. The Trojans use a variety of techniques to fool users into installation, including masquerading as video plug-ins, media players, download accelerators, and more. To be safe, avoid installing software from sites that prompt you to do so — always get software from trusted sources.
