SecureMac has released MacScan 2.9, which updates its malware blocking utility for full compatibility with Mac OS X 10.7 Lion. The latest release of MacScan, which includes the most recent malware definition signatures, can now also quit all running browsers when a scheduled scan is executed, and automatically checks for new updates by default when it is first run.

New Documents in Snow Leopard's TextEdit
In the Snow Leopard version of TextEdit, you can now create a new document by Control-clicking TextEdit's Dock icon (when it's running), and choosing New Document from the pop-up menu. This isn't a major feature, of course, since you can also just press Command-N while in TextEdit, but consider Control-clicking other applications' Dock icons to see what functions they might make available.
