So, I work for a company that makes products for Mac among other platforms. We never entered into the Developer Program because we weren't interested in selling our products in the Mac App Store (and we wouldn't be able to get them in there for specific reasons).
I only noticed fairly recently that as of Sierra, the "From Anywhere" option in terms of running apps is no longer visible, and that it's only possible to run our apps by way of using Terminal Command Line. Obviously, this presents a problem. However, we're concerned that, due to the rules of Mac App Store, we're worried that we won't be able to register and update our Mac apps so they can run on Sierra onward. This is despite us having no interest in selling anything in the Mac App Store.
Basically my question is: Do we have to abide by the rules of the Mac App Store in order to register for the Apple Developer Program, even if we have no intention of selling products there?
That's all, really.
