Apogee Maestro or Control will not properly recognize the Apogee interface if Mac user is logged into a Guest Account.  Maestro simply says “No Apogee Systems Found”.

• Confirm you have latest Apogee software installed, go to Apple Menu > System Preferences > Show All > System Accounts > My Account view > Set User Name to Admin, restart the Mac and Maestro will now launch successfully.
