IP Messenger is a free and open-source instant messaging application primarily used in Japan and other parts of Asia. While it[SQ]s not natively available for macOS, it[SQ]s possible to run it using tools like Wine, which allows some Windows applications to run on macOS. However, this is not an official or supported method and may not always work reliably. There[SQ]s no officially supported Mac version.

In short : there[SQ]s no dedicated IP Messenger app for Mac. Any usage on macOS requires emulation, which is not a guaranteed or straightforward process.
