Apple would seem to have been optimizing its code in the time between sending its latest MacBook Pro models into mass production and yesterday's launch, as we've just come across a software update for the brand new 2010 laptop models. Specifically aimed at the 15- and 17-inch machines -- which differ from the 13-incher with their Core 2010 CPUs and automatically switching graphics subsystem -- the patch is aimed at improving "graphics stability for high-performance video and gaming applications" while also squashing a variety of bugs. That hardly sounds like you'd be in danger if you didn't update, but we'd still advise swallowing the 258MB pill just to keep your aluminum-clad investment safe.
