Panic has released Transmit 4.3.2, a maintenance release of the file transfer program that contains fixes for an issue with connecting to servers using Private Keys, the loss of some custom Favorite icons, and an issue where the Transmit Disk Menu wouldn’t show all Favorites. It also updates its AppleScript support and Automator actions. ($34 new, free update, 26.5 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.
