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)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
