Hi all, I just got a Mac Pro running and it's using 10.7.5. So before setting up Plex for iOS, iPad/iPhone, you must install Plex on PC/Laptop/Mac. Because it is the Plex media server which stores and streams the Plex content stored on your iOS devices. It is necessary to set up Plex media server on your PC before you use Plex on iOS devices like iPhone/iPad.
