I was lucky enough to bring home a new MacBook Pro on Tuesday, and the first thing I noticed was a hefty software update waiting for it. Pushed out two days after the new MacBook Pros were announced, the 1.14 GB file improves graphics stability, external display support and USB 3 support. I'd go ahead and do this update before loading anything else on your new system. Find it via Software Update or download it from Apple's support site.
