Affects small selection of Pros
Apple has pushed out a new video update for MacBook Pros. The code is extremely narrow in focus, concentrating only on mid-2010 model 15-inch Pros still running Snow Leopard. It is however said to deal with serious graphical issues, including freezing or video disappearing entirely.
The file is a 51.45MB download, available in over a dozen languages. On top of other requirements users must already have a Mac updated to OS X 10.6.8.
