investigating possibility of macOS app

Hello @teamcons ,

we've been talking in the GTK chat previously. I am able to build jorts, but trying to launch it gives me this:

```

If dbus is an integral part of this app, I won't be able to take this any further. I haven't seen any (self-contained) macOS app in the wild that uses/bundles dbus and I am not going to figure it out. But that doesn't mean you're stranded: dbus is in Homebrew and there are ways to make it work, but it won't be the "it just works out of the box"-experience that people would come to expect (and still out of scope for what I can offer to do).
