DNSCrypt OSX Client is a user interface to conveniently start/stop dnscrypt-proxy and change DNS settings. It was specifically designed to use DNSCrypt with the OpenDNS public DNS resolvers. It includes a preference pane, a menu bar indicator, and a set of scripts for interacting with the system.
OpenXSpell aims to bring comprehensive and flexible open source spell checking to the Mac OS X platform. The project was born of a frustration with the limitations of the native AppleSpell spell checking service which provides support for only a very limited number of languages. OpenXSpell makes use of the excellent Enchant library, which makes it possible to use a number of different spell checking back-ends, including Aspell, ISpell, MySpell, and Hunspell.
