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

Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
