Apple today released MacBook Pro Video Update 1.0 (Snow Leopard), a new update addressing issues with freezing and blank video on mid-2010 MacBook Pro models.
This update addresses an issue where MacBook Pro (15-inch Mid 2010) computers may intermittently freeze or stop displaying video.
The update is a Snow Leopard version of the Lion update released three weeks ago. Additional information on the issue is available in a support document, although that document has not yet been updated to list the new software update as a first step for Snow Leopard users.
Apple has determined that a small number of MacBook Pro (15-inch, Mid 2010) computers may intermittently freeze or stop displaying video on the built-in display or on an external display connected to the MacBook Pro. In this situation, you may also see a restart warning message before the video is lost or the display turns black or gray. Affected computers were manufactured between April 2010 and February 2011.
MacBook Pro Video Update 1.0 for Snow Leopard weighs in at 51.45 MB and requires Mac OS X 10.6.8.
