New reports have suggested that Apple Twitter is planning to stop development of its Twitter for Mac app.

The app, which hasn’t been updated since June 2011 and therefore does not support the Retina MacBook Pro or Mountain Lion’s notifications, is popular among many Mac users as their primary Twitter client. Those users may be forced to switch to alternative third-party apps such as Tweetdeck if Twitter decides to stop working on its Mac app.

There has been no official announcement from Twitter about the end of Twitter for Mac, but TechCrunch claims to have spoken to “multiple sources” that have confirmed that Twitter has been discussing the end of development for the app.

Former TechCrunch writer MG Siegler tweeted: “Word is that Twitter made the call today: Twitter for Mac is done. They won’t kill it outright, but no further updates. Goodbye, old friend.”
