Apple today made a move to resolve some display problems that popped up among some of the first buyers of the redesigned MacBook Air.

The Mac maker released a software update for the 11-inch and 13-inch Air meant to resolve a "rare issue where MacBook Air boots or wakes to a black screen or becomes unresponsive."

Some of the early reviewers of the hardware noticed flickering horizontal lines sometimes appearing on the display of the 13-inch model or displays being discolored when waking from sleep. Other early purchasers noted similar issues on Apple support forums. Apple didn't acknowledge the issue publicly, but a leaked internal memo made its way to the Web that showed the company's support staff was aware of it. Boy Genius Report received the memo from an unnamed source, and published it in the first weeks the revamped Air hit store shelves.
