A Cure For Netscape Freezes? Frustrated that Netscape Navigator kept freezing on his Quadra 605, Scott Sykes <email@example.com> rolled up his sleeves and tried to figure out what the problem might be. The result is Netscape Defrost, a simple system extension that patches a Mac Toolbox call designed to return information about the machine's physical location on the globe. (You can access and set this information through the Map control panel.) Essentially, Netscape Defrost checks this data once, then passes that cached information back to any application that might be looking for it. Though I can't personally vouch for it, Scott certainly has a number of satisfied customers. Netscape Defrost is donation-ware and is designed to work with all versions of Netscape. [GD]
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.
