2011 MBP got off to a bit of a bumpy start for many users. Some encountered problems when outputting video through the Thunderbolt port to their Cinema Displays, while others found the new MacBook Pro freezing up when processing loads got that little bit too intense. The good news is that Apple now has a software update geared to remedying all these maladies, with changes specifically designed to improve graphics stability, 3D performance, and support for external displays and Thunderbolt devices. You can grab the download at the source link below or use Mac OS' built-in Software Update utility to freshen up your laptop with the latest code.
Update: A separate EFI Update (version 2.1) has also been rolled out. This one fixes the perplexing issue some reviewers had reported of seeing Intel's Turbo Boost disabled on some machines. Turns out the problem was related to Boot Camp and Apple has now resolved whatever was causing it. Click below for more info. Thanks, Francesco!
