Hi -

The Doser 2, to me, seems to be the best dosing option out there for my needs. I already have an Apex DOS but two pumps is limiting and the size of the unit prevents me from adding more easily.

I do not have access to a PC of any kind however and this is what's holding me back from moving forward with a Doser 2. As I understand it, with a Mac only household, I can utilize all the Doser 2 programming feature but will not be able to update the firmware?

Thanks,
Paul
