Apple has issued EFI Firmware Update 2.6 for the MacBook Air models that were released in June 2012. The update resolves a color issue with connected HDMI displays, a bug that caused the system to freeze if a Thunderbolt device was unplugged while in standby mode, and a problem with properly booting Windows using Boot Camp. It requires OS X 10.8.2 Mountain Lion. As always with firmware updates, we recommend relying on the App Store to ensure you get the firmware update for your specific model and being careful not to interrupt the update process.

Although many people never change their toolbars from the default settings, all standard toolbars on the Mac offer six states: icon only, text only, and icon and text, with all three coming in normal and small size. You can change them by choosing View > Customize Toolbar.
But there's a shortcut that makes it easier to check out each variant. Simply Command-click the toolbar lozenge at the upper right of a window, and the toolbar switches to the next view. Click it enough times, and you cycle back to the start.
