Apple has added a nice feature in OS X Lion that allows you to synchronize the Address Book with your Google Contacts. Just launch the Address Book, go to Preferences, and select the On My Mac in the Accounts pane. Next, check the Synchronize with Google option, click the Configure… button and enter your Google account username/email and password. That’s it, no more missing contacts!
Quick Look on OS X is a great feature for previewing the images, sounds, videos and text files. However, for some reason Apple has chosen not to allow selection in Quick Look, you can’t click and drag to select the content. We can fix this, and here is how.
Here is how to move your Dashboard Stickies widget information to a new user or a new Mac OS X system. All the text you wrote on the Stickies is contained in the /Users/[your_username]/Library/Preferences/widget-com.apple.widget.stickies.plist file.

Mac OS X Lion introduced MobileBackups, a new TimeMachine feature that stores local backups of your files while you are away from your main TimeMachine backup disk. This feature stores filesystem snapshots inside a virtual drive on your local disk, so should not be considered as a main backup strategy. The system automatically does periodic snapshots, but you can also manually initiate the process.
To make a local snapshot of the current state of your files, enter this command in your Terminal window:
sudo tmutil snapshot
It should complete almost instantaneously, giving you a tick in the TimeMachine backups timeline.
