About the OS X Lion v10.7.3 Update

Display a note when the screen is locked in OS X Lion

Lock message

New in OS X Lion is the ability to display a message when the screen is locked. This is useful to inform your co-workers not to meddle with your Mac in your absence. Go to System Preferences > Security & Privacy. Under the General tab, check the option “Show a message when the screen is locked” and key in your note below. If you’re not able to check the option or key in the note, click on the lock icon at bottom left corner to unlock for editing.

Merge video clips using QuickTime Player in OS X Lion

QuickTime Player in OS X Lion has the capability to merge multiple video clips into one movie. Simply drag the clips you want to add into a movie window. QuickTime Player will automatically scales or crops the clips so they match the dimensions of the movie. You can even trim the head or tail of any clips before saving the combined clips as new movie. If your video editing is just trimming and combining clips, instead of the more elaborate iMovie, you can just use QuickTime Player to achieve the same result.

Hide unwanted System Preferences options in OS X Lion

If you find the options in System Preferences overwhelming, you can selectively hide those unwanted options from displaying.


Open System Preferences app. Click and hold on the “Show All” button to reveal a drop down menu. Select “Customize…” at the bottom of the menu.


From the customize screen, uncheck those options that you want to hide, and then click the “Done” button to save the changes.


Finder’s Duplicate Exactly in OS X Lion

You might be familiar with the File > Duplicate (Command-D) command in Finder. New in OS X Lion is the function “Duplicate Exactly”. You can access Duplicate Exactly by pressing Command-Option-Shift keys while in the File menu. The “Duplicate” menu item will change to “Duplicate Exactly”. Or you can just press the keys Command-Option-Shift-D.

When you choose the normal “Duplicate” command, OS X will create a copy of the file and set the file owner to your login account. “Duplicate Exactly” will create a copy of the file but the ownership of the file follows the source, thus ensuring the exact same file even for file permissions.
