Firstly, I didn’t realize I had to install the mac Bonjour Print Services program, which of course tried to install a bunch of other Mac bloatware, (iTunes hate it, QuickTime, no need). Then I downloaded iC Pro again and received the activation code which has to be installed on your eLicenser…Once all that was complete, re-booted my system and all was a go. I am using it on my S4 so the screen real estate is small but it works instantaneously, no lag at all. So I will be purchasing the app. Quite often I am adding instruments to my clients recordings and being able to be in the cutting room or Iso booth and use this will be invaluable. I have had the Frontier Transport for several years and it worked great in my smaller studio, but I found in my larger space the range gets limited
