Rated 3.93/5 based on 592 customer reviews

The firmware update can be downloaded through Software Update on the select models, or users can download it directly here.

Last month Apple released the Mac Book Pro SMC Firmware Update 1.6, which addressed a similar issue on other models.

The update addresses a very specific issue owners of the Mac Book Pro (15- and 17-inch models, Early 2011) and Mac Book Pro (15- and 17-inch models, Mid 2010) were having.

Though rare, the issue would cause the laptops to unexpectedly shut down or stop functioning after more than 1,000 battery charge cycles.

Its also up to 60 percent faster than the previous generation,2 so you see more frames per second in 3D games and get greater speed and responsiveness for your HD video projects. Imagine accessing multiple streams of uncompressed HD video from your Mac Book Pro at speeds that let you edit an HD feature film in real time.

Apple has released three System Management Controller (SMC) firmware updates for its Mac Book lineup: Mac Book Pro SMC Firmware Update 1.8 (703 KB; mid-2012 models), Mac Book Pro Retina SMC Firmware Update 1.2 (712 KB; mid-2012 models), and Mac Book Air SMC Update 1.9 (1.09 MB; mid-2012 and mid-2013 models).

All three address battery-related issues, where your system could hang or the battery could stop functioning altogether if the battery level goes below 1 percent.

With Turbo Boost speeds up to 3.6GHz, these processors bring more power to everything you do. The integrated Intel HD Graphics 4000 processor boosts performance by up to 60 percent.1 That extra power gives you a smoother, more fluid experience than before.

Its still highly efficient, too, so you get long battery life when youre out and about.
