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 Long Hierarchical Menus
If you right-click (or Control-click) on some item, such as a file in the Finder, and one of the sub-menus has many options (Open With is a frequent culprit), it may take several seconds to open, even on a fast machine, which is annoying if you did not actually want that sub-menu.
The trick is to not pull the cursor through the menu, but in a curve around it, so the cursor does not touch any menu items until lower on the list where you wanted to go.
