my macbook came from ebay, and the previous person had installed toast, except without activating the serial for it, which i dont have. For some reason one extension associated with toast conflicts with the latest update, and has completely disabled my quite new and expensive (to me) audio interface. So i cant do any work until i get rid of this toast program. I'm assuming dragging and dropping the application to the trash will only delete the program and not the extension. Is there a proper/thorough way to do this so this problem goes away without messing anything up in the process??
