FWIW, while Craft’s native app-ness will always give it an edge, I think Obsidian can go toe-to-toe with it—with a bit of fiddling. Try the Minimal theme, and install the Minimal Theme Settings plugin to maximize customizability. The California Coast theme is also very “macOS-like”—it uses the Style Settings plugin for further customization.
I think we can get it pretty close. I’ve been hoping to help the devs add many Menu items, for instance—just haven’t had the chance to draw up the plans from this thread yet: Obsidian users: What would make the app more Mac-native?
Last, if you’re indexing your notes in DEVONthink, be sure to try the DEVONlink plugin mentioned here: Really cool linking of Devonthink and Obsidian
