MarsEdit
Over on The Sweet Setup, MarsEdit was chosen as the best Mac WordPress client for macOS. By some metrics, WordPress powers just over 25% of the world’s websites. While the web editor is much improved, there is something nice that working in a native macOS app. MarsEdit has been around for years, and is really in a class of its own.
I recommend you read the entire review, and then give MarsEdit a shot.
You can download it on the App Store for $39.99.
