MacArthur

MacArthur is a chat software that provides an effortless way to set your away message on multiple clients at once. With MacArthur, you can choose to display the location and title of your next event as the default away message by linking the app to your specified iCal calendars. Alternatively, you can override this with a personalized message of your choice.

Additionally, MacArthur offers the option to set all supported chat clients' status as "available" all at once, without the need to individually toggle the status for each. The software supports a wide range of clients, including iChat, Yahoo! Messenger, Adium, AOL Instant Messenger, and Proteus.

With limited support, MacArthur also provides compatibility with partially supported clients, such as MSN Messenger, Fire, and IRC in a terminal window. Overall, MacArthur is an incredibly useful and functional software for managing multiple chat clients with ease.
