On Mac, the only thing that looks and feels native is the actual native Objective-C or Swift framework.
Everything else has subtle differences, and yes, your users will notice. You may as well just ship a janky Electron app like Teams. But if you want to impress your users with a native feel, it's the Apple toolkits or nothing.
In my case the users were just really happy we solved the problem, I don't think they would care if it ran on minecraft redstone.
