Navigate to the folder (the directory) in which SuperCollider resides and double-click on it (the red and white balloon icon). An untitled document with text such as
appears in the top left of the screen. The document functions as a "Post Window," so-called because SuperCollider uses it to "post" notifications.
On the bottom of the screen are two more windows. One is called "localhost server" and the other is "internal server." Click on the "boot" button on the localhost server. The words "localhost" in the black box of the button turn red and the word "Boot" on the button changes to "Quit." More text, such as
will print to the post window. The localhost server is now ready to be used. Activate the internal server, if you wish, in the same way.
Open existing SC documents with File->Open... or cmd-o. Use File->New or cmd-n to create new documents.
SuperCollider documents generally have .scd appended to their file names; however, SuperCollider can read and write documents in Rich Text Format (.rtf) and several other formats, as well.
