Riverdark is a small (one person) software company, providing various little tools and applications for Mac OS X. We are dedicated to making tools which are both powerful and configurable, while remaining easy-to-use. All our software is available in Universal Binary format, to work on both PowerPC and Intel Macintosh systems... wait, that's not really a concern anymore, is it?

Really, the only available software here at this point is Atlantis, a MU* client for Mac OS X which dates back to MacOS X 10.3 (Panther)—hence the PowerPC reference—but has been recently updated for macOS 10.15 (Catalina).
