Apple has released Server Admin Tools 10.7.5, which includes updates to its set of administration applications for use with Mac OS X 10.7 Lion Server. In particular, the Server Admin and System Image Utility tools add NetBoot/NetInstall model filters for MacBook Pro and MacBook Air (Mid 2012) models. Additionally, the System Image Utility improves reliability of booting from NetRestore images, and the Workgroup Manager correctly sets the password expiration date for Open Directory users and shows the names of members of Active Directory groups.

Enter Dashboard, Expose, or Spaces Temporarily
Hold down F9, F10, F11, or F12 (or whatever you've set for the Expose and Spaces keyboard shortcuts) for a few seconds, and then release the key to enter and leave the appropriate mode without having to press the key again. This is particularly useful for Dashboard, in which you can check the contents of a widget and then return to your work with only a single key press.
