Thank you for your interest in BatchPhoto.
Q1: The trial version contains all editions of BatchPhoto (Home, Pro and Enterprise). So when launching the app you will have the option to select the Enterprise edition when running the trial version.
When selecting Enterprise at startup the Monitor will start automatically if not you can start it manually from File > Launch Monitor.

Q2: Yes, the same activation code that you purchase for BatchPhoto works on both Win and Mac computers so you can move the license from Mac to Win and vice-versa. However you need a license for each computer where you use BatchPhoto.
