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.

Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
