In the time honored tradition of releasing bad news at the close of business on a Friday, Twitter announced via its Twitter Support account that it was removing its Mac client from the the Mac App Store and discontinuing support for the app:

Twitter gained a native Mac client when it acquired Tweetie for Mac from Loren Brichter in 2010, but the company’s support for the app over the years has been half-hearted at best. As John Gruber explained on Daring Fireball:

Twitter dumped Tweetie’s codebase years ago, of course, and their Mac app has been garbage ever since they did. It’s all fine, really, so long as they continue to allow third-party clients like Tweetbot and Twitterrific to exist. But this “Mac users should just use the website” attitude is exactly what I was talking about here as an existential threat to the future of the Mac.

Twitter’s move is not surprising given the history of the app. Most Mac users I know moved on to third-party clients years ago. However, Gruber’s broader point is an important one. There has been an increasing trend away from native Mac apps and towards web apps and cross-platform apps based on technologies like Electron. Many of these non-native solutions are resource hogs, and even the best often fail to take advantage of OS-level features, which makes them feel out of place among native apps. Perhaps the rumored Project Marzipan is designed to reinvigorate Mac development, although it’s hard to see that working if companies like Twitter simply don’t care to provide the best experience on macOS.
