MacJams is an online community of people who are interested in creating or presently create music using the Macintosh platform, as well as people who are interested in listening to such music.

Our goal is to create an online environment where musicians and aspiring musicians can come to improve their craft and gain exposure to their music. At the same time, MacJams is a repository of fantastic music for listening and download by anyone who is a fan of good music.
