Updating firmware on macbookpro

Rated 3.93/5 based on 715 customer reviews

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.

The Mac Book Air SMC Update also throws in a solution for the possible problem of the system not recognizing the battery when it goes below 1 percent.

As always with firmware updates, we recommend relying on Software Update or the App Store app to ensure you get the firmware update for your specific model, and be careful not to interrupt the update process.

The mid-2015 model was released in May with internals component upgrades and a pressure-sensitive Force Touch trackpad.

In this tutorial we'll look at what to do if your Mac stalls or freezes during a operating system software update.

For graphics-intensive applications, the 15-inch Mac Book Pro automatically switches to the NVIDIA Ge Force GT 650M discrete processor with up to 1GB of video memory.

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 describes Internet Recovery as follows: If your Mac problem is a little less common — your hard drive has failed or you’ve installed a hard drive without OS X, for example — Internet Recovery takes over automatically.

It downloads and starts Lion Recovery directly from Apple servers over a broadband Internet connection.
