  1. Install Jack if you haven't already done so (JackOSX.0.92_b3.zip)
  
     (Note that MacOS might warn about a program inside the Jack package being 32 bit.
      You can safely ignore this message, the program ("Jack Pilot") is just an alternative to QJackCtl.)
 
  2. Launch the "QJackCtl" program included with Radium. This program lets you set audio parameters.
  
  3. Press the "start" button in QJackCtl.
  
  4. Wait until the status changes from "starting" to "started".
     (See below if it didn't start)
  
  4. Launch "Radium".
  


If Jack didn't start in point #3, first try again. If that didn't work, try selecting different input and output devices.
You might also want to try to disable audio input. You can also start jack in a terminal by executing
this command:

  jackd -dcoreaudio
