Michael, you may want to make sure you have the current ActivDriver, which you can download from http://www.prometheanplanet.com/en-us/Support/ProductPage.aspx?product=22. You’ll see the drivers on the right side of the page. After installing that, you should see the ActivManager icon in the top menubar on your Mac. When you click that, calibration will be an option in the menu.
