Mountain Lion offers a new feature called Power Nap, but since it’s limited to only a few recent laptop Mac models, most people probably haven’t seen it. In short, Power Nap enables supported Macs to wake up briefly to back up via Time Machine, check for email via Mail, receive new messages in Messages, and update iCloud-related data, including calendar events, contacts, reminders, notes, iCloud documents, and photos in Photo Stream. Over at Macworld, our friend Dan Frakes explains just what Power Nap can do, how you use it, why it works on so few models, and more. follow link
File Email with a Key in Apple Mail
In Mac OS X 10.4 Tiger or later, you can use the simple and fun MsgFiler Mail plug-in to file Mail messages using keyboard shortcuts.
New in Apple Mail 4 (the 10.6 Snow Leopard version), to assign a keyboard shortcut to any mailbox on the Move To or Copy To submenu, you can also open the Keyboard pane of System Preferences, click Keyboard Shortcuts, and select Application Shortcuts in the list on the left. Click the + button, choose Mail from the Application pop-up menu, type the name of the mailbox in the Menu Title field, click in the Keyboard Shortcut field, and press the keystroke combination you want to use. Then click Add.
