Apple has released a rare Supplemental Update for Mac OS X 10.6.7, exclusively for the most recent edition of the 13-inch MacBook Air. The update addresses an issue that makes the system unresponsive when using iTunes, and Apple recommends it for all applicable MacBook Air users. The Supplemental Update is available via Software Update, or directly from Apple’s Web site. (Free update, 461 KB)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
