Focusing on resolving some compatibility issues with OS X 10.8 Mountain Lion, The Omni Group has released version 1.10.3 of its OmniFocus task management app. The maintenance update fixes some integration issues with Apple Mail on Mountain Lion, ensures that OmniFocus works correctly with MailTags 3.1 and later, squashes a bug with the “allowed mail senders” scripting property, and fixes a regression with the Japanese localization that made the Help menu item non-functional. While iCal Sync isn’t available when running on Mountain Lion, Calendar export in the Sync preferences will still work. ($79.99 new, free update, 22.4 MB, release notes)
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
