The beauty of Proteus is its multi-protocol support all within a single application. With Proteus you can log into all your IM accounts with ease. There is no need to have several IM applications open when you can just use one! We offer support for AIM (including .Mac accounts), MSN, Yahoo! (including Yahoo! Japan), ICQ, Jabber (including Google Talk), iChat Bonjour, Gadu Gadu, and Sametime with more in the works!

Features:

A tasty interface
With a beautiful and intuitive Mac OS X interface, Proteus makes chatting with your friends and family a no-brainer. It has all the things you need, including a simple drawer to group all your conversations and remove the clutter from your desktop. Proteus just feels like it is a part of your Mac.

A little extra
Proteus Extras make customizing Proteus to your tastes a breeze. Message views, sound packs, and emoticons are among the many extras Proteus has to make you feel right at home and in control.

Share the love
Proteus supports drag-and-drop file transfers for MSN, Yahoo, AIM, and Jabber. We are constantly working to make file transfers that much better in future versions.

Working well together
Proteus works seamlessly with Mac OS X. Using Address Book, Proteus lets you easily display real-names instead of usernames in your contact list. Using a open-source technology called Webkit, we are able to provide customized chat views that fit every personality.

We even support UNIX technologies thanks to Mac OS X's BSD heritage, such as running shell scripts when someone messages you or displaying rich LaTeX equations!

Requirements:
OS X 10.5.8-10.7
Universal Binary
