Even Apple can't be bothered to make quality Mac apps for all their software. There is no News app for the Mac, nor a homekit app. And the Mac App Store doesn't feel like a native app to me.

However, it doesn't really bother me. I'm extremely happy using macOS. Hardware is excellent as well. Companies hawking their wares without decent client apps, like Slack, don't get my sympathy. I'll use it when I must, and the minute that need drops away, then it's gone from my system.
