Am intrigued by your comment, as my interpretation of what you want and what you're doing seem to be at odds with each other.
My assumption is you want to get a paid developer role, whereas your side project seems to be satisfying personal curiosity (otherwise, you'd definitely already have an answer to the question of whether your Mac app would make a few bucks). The latter is immensely important in its own right, but quite likely won't solve the first problem itself (again, if it were to, you'd have a surer answer to whether it was likely to make money or not).
I flamed out of university without a degree at all, but put myself in places to get a CMO role (which I ultimately hated, but still...) at a startup because I aligned my side projects with what I wanted from my career rather than just things I wanted to build. It's a hard choice, but it's one that probably has to be made.
Also, your nanodegree looks to be unused as-is, with little link to the work you're currently doing (sure, it's an app, but Android/mobile to MacOS/desktop is about as far as you can stretch the "app" link) - how are you framing it with employers?
