 # Messages For Macintosh
 Messages for Macintosh is a software suite for classic Macintosh (System 2.0 through MacOS 9.2.2) systems to interoperate with Apple iMessages via a familiar interface, with [supporting software](https://github.com/CamHenlin/imessagegraphqlserver) running on a newer Mac computer.
