That's not enough for me not to worry about it - that leaves 45% of the Mac user base unable to run the software. That's a lot.

I currently have some MoI users running on 10.6 right now. I'm still hoping to support that on v4 but I'm not entirely sure if that will happen or not, it's possible I may need to require 10.7 minimum. But certainly jumping to require 10.11 is a very long way off from what I'm shooting for.

But only when it's running 10.11, is that correct? No support on any currently released version of OS X, even 10.10 ?
