Apple releases Lion Recovery Disk Assistant software for creating recovery disk on external USB drive


When you install or upgrade to Mac OS X Lion, a Recovery HD volume is created on your Mac hard disk as part of the setup. The Recovery HD allows you to reinstall Lion, access Disk Utility, restore from Time Machine backup or browse the web with Safari.

Apple has released Lion Recovery Disk Assistant software, allowing you to create the same Recovery HD volume on an external USB disk or thumb drive. This is useful if your Mac hard disk is not usable or you are replacing the internal hard disk.

Creating the external USB Recovery HD volume is also an alternate way for you to have a clean install of Mac OS X Lion, instead of manually creating the boot disk.

In order to create the external Recovery HD, your Mac’s hard disk must have an existing Recovery HD. The external USB hard disk or thumb drive must have at least 1GB of free space. The Recovery HD volume on your external USB drive is not visible in Finder. To boot from the USB external drive, hold down Option key while Mac is booting, and select the Recovery HD from the boot up screen.

Apple has also created a knowledge base article describing more about Lion Recovery Disk Assistant. The article noted:

  • If the computer shipped with Lion, the external recovery drive can only be used with the system that created it.
  • If the system was upgraded from Mac OS X v10.6 Snow Leopard to Lion, the external recovery drive can be used with other systems that were upgraded from Snow Leopard to Lion.

Access using Option key

Access using “Go to Folder”

An alternative is to select the option “Go to Folder” under the Go menu or using the shortcut keys Command+Shift+G. Enter “~/Library” under the “Go to the folder” prompt.

About full-screen mode in Mac OS X Lion


Full-Screen mode is a new system wide feature in Mac OS X Lion that apps can take advantage of. Many standard Lion apps such as Mail, iCal, Safari, FaceTime and Preview are full-screen apps. Apple apps such as iPhoto, iMovie, GarageBand, Keynote, Pages and Numbers were updated to work full-screen, and you can expect third party apps to follow.

  • You can tell if an app supports full-screen by the double-end arrow icon at upper right corner of app window. Click on this icon will switch the app to full-screen mode.
  • When in full-screen mode, the menu bar and the dock disappear.
  • Move the cursor across the top of the screen to gain access to the menu bar.
  • To gain access to the Dock, first move the cursor to the edge where the Dock is pinned. Then swipe or move the mouse in the same direction again. This two-steps process is designed so that the Dock will not easily block any buttons or elements on your app when you accidently move the cursor off the edge of screen.
  • Press ESC to quit the full-screen mode. Or you can reveal the app menu, and click on the double-end arrow icon at upper right corner to exit full-screen mode.
  • The shortcut keys to enter full-screen mode is Control-Command-F. You press the same shortcut keys to exit full-screen mode.
  • Full-screen mode is per app window. For example if you have two windows under Safari, you can have one window in full-screen mode while the other window remains the same.
  • OS X Lion create a Space for each full-screen app window. You can easily switch between full-screen app windows using the three fingers swipe left or right to swicth between Spaces.
  • When in full-screen, you can access Mission Control as usual by swiping up with three fingers.
  • When in full-screen, you can access Launchpad as usual by pinching with thumb and three fingers.
