Sorry but this answer is a bit complicated:
The first part is easy. Yes this unit can be used to connect to a MultiPlus using Victron Connect which will run on a Mac or PC.
If you are using Victron Smart Lithium Batteries then you need to install the VE Bus BMS Assistant as part of the programming, and at the moment (as of March 2020) that feature is not available in Victron Connect and can only be done with VE Config which requires a PC.
