Apple has released MacBook Air and MacBook Pro Update 2.0, a standalone package for both notebooks that aims to improve compatibility with certain USB hardware. The update also improves graphics on said computer models, according to Apple.
A technical note on Apple’s Support Downloads site says, “This update includes graphics performance and reliability enhancements and improves compatibility with some USB devices.”
Apple recommends to install the 127.07 MB update on “all Mac notebooks introduced in June 2012.”
If you’re not sure whether your MacBook needs it, don’t worry. Use the Software Update tab in the Mac App Store to see if Apple serves MacBook Air and MacBook Pro Update 2.0 to you.
If the update does appear listed as available for your computer, hit install. If it doesn’t, it means you don’t need it, so don’t bother looking for a manual download elsewhere. Plus, the manual download link offered by Apple doesn’t work (at the time of writing).
However, for the sake of everyone’s understanding, Apple is specifically targeting the MacBook Pro and MacBook Air models introduced at WWDC 12.
Those include the 15-inch MacBook Pro with Retina display, the updated range of non-Retina MacBook Pros, and the updated MacBook Airs with new processors and graphics.
Under System Requirements, Apple only mentions OS X 10.7.4 Lion. Customers running OS X 10.8 Mountain Lion will not require this update. The same goes for OS X 10.6 Snow Leopard installations.
The supported languages for this update include Deutsch, English, Français, Español, Italiano, Nederlands, Dansk, Norsk Bokmål, Polski, Português, Chinese, Japanese, Korean, and many others.
The respective MacBook Air and MacBook Pro models shipped with OS X (10.7) Lion pre-installed. Customers who purchased a Mac after WWDC 12 were eligible for a free copy of OS X Mountain Lion.
Update: the manual download link is now available.
