Apple has released two updates for recent MacBook models that address several stability and reliability issues. The MacBook Pro Software Update 1.4 introduces changes that improve the reliability of graphics rendering and external display support, as well as Thunderbolt device support. The MacBook Pro EFI Update 2.1 seems to have a similar set of targets, but also resolves an issue with Turbo Mode in Boot Camp. As always with firmware updates, do not disturb or power down your MacBook Pro while installing, since it could leave the Mac in a non-functional state. Both updates can be downloaded and installed via Software Update, or through their individual pages on Apple’s Web site. (Free, 132.69 MB and 3.06 MB respectively)
