Adium
Adium is a free and open-source instant messaging client for macOS that lets users connect multiple messaging accounts across different services into a single unified interface. Based on the libpurple protocol library, it supports a wide range of messaging platforms, OTR encryption, file transfer, and integration with the Mac's Address Book and Notification Center. Adium is popular with users who prefer open-source software and want to consolidate multiple IM accounts without running separate clients for each service.

1 suggestionAdium has not been actively maintained for several years, with no public releases or development activity visible since the mid-2010s. The app continues to run under Rosetta 2 on Intel Macs today, but will stop launching entirely when Apple removes Rosetta in macOS 28 (September 2028). The last released version (1.5.10, circa 2014) was built for Intel architecture only, and the project has not shipped a native Apple Silicon build. If you rely on Adium for messaging, you should plan to migrate to an actively maintained alternative before September 2028. Consider Slack for team communication, Discord for community chat, iMessage/FaceTime for macOS-native options, or Thunderbird which offers XMPP support and is actively maintained across both Intel and Apple Silicon architectures. For technical users who specifically need multi-protocol support, Gajim is another open-source option available on macOS with native Apple Silicon support in recent releases.
