> Apple has not pulled off a successful App Store concept for MacOS yet

They really did, for the first year or two of the Mac App Store's existence. It was great. All of the "$10 utility apps" would be there today if not for Sandboxing.

Maybe this wouldn't have included the apps where the 30% or poor support for upgrades/subscriptions would really impact sales (Adobe, Microsoft, perhaps, interestingly, Sketch...), but sandboxing is the only outstanding issue that prevents you from shipping an app to the Mac App Store.
