TechCrunch columnist MG Siegler has a source saying that the Twitter for Mac app will be ending soon. The application won’t be killed off completely and users will still be able to download it. This is unfortunate because the Twitter For Mac app is unstable and seems to crash a lot so I reverted back to just using Twitter on the web. The Twitter For Mac app also does not support Retina Display on the new MacBook Pros. If you still prefer to use desktop software for Twitter, I would definitely recommend using TweetDeck. TweetDeck is constantly updated with new features.
