TwitterTicker for Mac is a screensaver that promises to display content from your Twitter feed. Unfortunately, despite our best efforts, we were unable to get it to run properly. We really like the idea of this screensaver; but in its current incarnation, we can't recommend it.
Our first issue with TwitterTicker was that once it was installed, we couldn't figure out how to get it to connect with our Twitter account. In the Screen Saver Options menu there was a place for us to select our Twitter account from a drop-down menu, but our Twitter account wasn't listed, and there didn't seem to be any way to enter it. After some research, we determined that we actually had to enter our Twitter account information into Apple's Mail, Contacts & Calendars screen in System Preferences. Once that was done, we returned to the screensaver preferences and tried to run TwitterTicker for Mac. The screen went black and the word "Loading" appeared. We briefly saw one tweet, but then the whole thing crashed. This happened repeatedly, sometimes never getting past the Loading screen. This is a shame, because TwitterTicker for Mac is a cool concept. It just doesn't seem to work.
TwitterTicker for Mac installs and uninstalls without issues, but unfortunately, these are the only things it really does well.
