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.

 
 

Security Update 2011-004 (Leopard/Leopard Server)

Send Article to a Friend

While Mac OS X 10.6.8 resolves numerous security vulnerabilities for Snow Leopard users, those still using Mac OS X 10.5 Leopard should download and install Security Update 2011-004. The most important fix is to AirPort, and it prevents an attacker on the same Wi-Fi network from causing your Mac to reboot. Other affected aspects of Mac OS X include ColorSync, CoreGraphics, ImageIO, MySQL, patch, Samba, servermgrd, and Subversion. Separate standalone updates are available for Leopard and Leopard Server, though it’s still easiest to let Software Update do its thing. (Free; 256.4 MB, 499.8 MB)

10.6.8 update broke many PS printers - search for paused_printers on the Apple discussion boards or see:

I expect to see a quick revision of that update from Apple or a plethora or printer driver updates.
