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.

Send Article to a Friend

Apple has released Security Update 2014-002 for 10.8 Mountain Lion, 10.7 Lion, and 10.7 Lion Server, with many of the same security fixes applied to the recently released OS X 10.9.4 Mavericks (see “OS X 10.9.4 Includes Wi-Fi, Wake from Sleep Fixes,” 30 June 2014). All three releases receive updates to the certificate trust policy, as well as fixes for vulnerabilities in maliciously crafted ZIP files, cURL re-using NTLM connections, and the Dock’s handling of messages from applications. The Mountain Lion Security Update also patches vulnerabilities related to a kernel memory issue with graphics drivers, a validation issue in the handling of OpenCL API calls, and array indexing with IOAcceleratorFamily (see the full list of patched vulnerabilities). (All updates are free. For 10.8 Mountain Lion, 139.3 MB; for 10.7 Lion, 134 MB; for 10.7 Lion Server, 184.3 MB.)
