Apple has started rolling out a new software update for all the Macs that it had introduced in June 2012, including the MacBook Air and the 15-inch MacBook Pro Retina.
The MacBook Air and MacBook Pro Update 2.0 weighs in at 127MB and the change-log from Apple suggests that it includes “graphics performance and reliability improvements and improves compatibility with some USB devices”.
Apple recommends this update to all the June 2012 MacBooks, so do update if you own one of them. Early reports suggest that the update has fixed the freezing issues that many people experienced for around 30 seconds when they plugged in a USB drive to their Retina MacBook Pro(s). It, however, does not fix the image burn-in issues on the Retina MacBook Pro(s) with an LG display panel, or the flickering issues that have plagued rMBP owners since quite sometime.
