Important Security Settings Information!
Both Mac and PC now have stringent security settings for software they don't make themselves. You may need to set this up on your computer before downloading and installing GYST. Attached here is a pdf with those instructions. You may get messages that caution you about the download, but we have scanned all our downloads and they are virus free.
