In light of the recent security breach at certificate authority DigiNotar, Security Update 2011-005 removes DigiNotar from the list of trusted root certificates and from the list of Extended Validation (EV) certificate authorities, and configures default system trust settings so that DigiNotar’s certificates, including those issued by other authorities, are not trusted (for more info, see the links in "Firefox 6.0.2," 8 September 2011). The release is available for both Mac OS X 10.6 Snow Leopard and 10.7 Lion, and it updates both Mac OS X and Mac OS X Server. (Free, 869 KB for Snow Leopard, 15.59 MB for Lion, release notes)
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.
