Apple has released several updates, including patches for iTunes and Cinema Displays and new printer drivers.
iTunes 10.1.1 addresses a handful of issues including: music videos not playing on Macs equipped with NVIDIA GeForce 9400 or 9600 graphics and failing to sync with iOS devices; iTunes unexpectedly quitting when deleting a playlist and when connecting an iPod to some older Mac models.
LED Cinema Display Firmware Update 1.0 addresses intermittent audio issues with the 27-inch model.
Apple notes that after updating, headphone redirection will still occur. Plugging headphones into a Mac connected to an LED Cinema Display (27-inch) may limit the audio output choices in the Output tab of the Sound preferences to headphones only.
On a Mac Pro, you need to switch the analog line-out port, optical digital out port, and external audio devices (such as USB or FireWire) manually using the Output tab of the Sound preferences. This is due to the discrete audio engine these computers use for audio processing.
Apple has also released new software for Canon, FujiXerox and Lexmark printers, including multifunction, all-in-one devices.
Aperture 3.1.1 has been available for several days and addresses issues with importing images, iLIfe compatibility and publishing photos to MobileMe, Facebook and Flickr among others.
All updates are also available via Software Update.
