C-Command Software has released SpamSieve 2.9.10 with added compatibility for what became the final release of OS X 10.9 Mavericks. As with the previous update (see “SpamSieve 2.9.9,” 9 October 2013), C-Command recommends that you update to SpamSieve 2.9.10 before installing Mavericks, but if OS X 10.9 is already installed then you should choose SpamSieve > Install Apple Mail Plug-In. The new version also updates various parts of the manual. ($30 new with a 20 percent discount for TidBITS members, free update, 10.8 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.
