Apple has released a minor update to its Swiss Army knife of desktop media and iOS syncing software, iTunes 10.1.1. The bugs fixed resolve an issue where music videos wouldn’t play back properly on certain Macs, and another where iTunes could unexpectedly quit when deleting playlists. Also corrected are syncing issues: one affecting PowerPC processor-based Macs and another where music videos wouldn’t sync to iOS devices. (Free, 90.5 MB)
Thoughtful, detailed coverage of the Mac, iPhone, and iPad, plus the best-selling Take Control ebooks.
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.

i did the upgrade on two of my macs, a 13" MacBook and an Intel iMac, both running 10.6.5. Immediately after the upgrade, both crashed EVERY time I tried to open iTunes and consequentially sent a report to Apple. I had to restore to 10.1 via TimeMachine to get iTunes to load and run. Anyone else notice this behaviour?
