Apple has issued two System Management Controller (SMC) updates for the MacBook Air — version 1.5 for models released in June 2012 and version 1.6 for models released in 2011. Both updates enable Power Nap support when running OS X 10.8 Mountain Lion, while the version 1.5 update for mid-2012 MacBook Air models also fixes several sleep and wake issues that should improve overall stability. Version 1.6 (for mid-2011 models) requires 10.8, while version 1.5 (for mid-2012 models) requires 10.7.4 or later. To ensure you get the firmware update for your specific model, we recommend relying on Software Update. (Free, 698 KB/663 KB)
Open Files with Finder's App Switcher
Say you're in the Finder looking at a file and you want to open it with an application that's already running but which doesn't own that particular document. How? Switch to that app and choose File > Open? Too many steps. Choose Open With from the file's contextual menu? Takes too long, and the app might not be listed. Drag the file to the Dock and drop it onto the app's icon? The icon might be hard to find; worse, you might miss.
In Leopard there's a new solution: use the Command-Tab switcher. Yes, the Command-Tab switcher accepts drag-and-drop! The gesture required is a bit tricky. Start dragging the file in the Finder: move the file, but don't let up on the mouse button. With your other hand, press Command-Tab to summon the switcher, and don't let up on the Command key. Drag the file onto the application's icon in the switcher and let go of the mouse. (Now you can let go of the Command key too.) Extra tip: If you switch to the app beforehand, its icon in the Command-Tab switcher will be easy to find; it will be first (or second).
