How to Change the Twitter for Mac Icon (And Others, Too)

Twitter for Mac is one of the great apps introduced alongside the Mac App Store. Since then, it’s been updated twice, and the app’s icon changed (some would say for the worse) both times. Here’s how to change the icon back to whichever you like best.

  1. Find Twitter for Mac in the Finder(s aapl). You can do this by either looking for it yourself (it will most likely reside in [Your name]/Applications) or by right- or Control-clicking on Twitter in your Dock and choosing Options > Show in Finder.
  2. Once you’ve located the app, quit it if it’s running, then right-click on the icon and choose Show Package Contents. This lets you look inside the app bundle to find the files it needs to run, so be careful about what you do as you explore. Next, navigate into the Contents folder, and then find the Resources folder inside that. You’ll see three .icns files — the 3D one from the latest update and two others.
  3. If you try to change the files while they’re still in the application bundle, it won’t work, so drag the three files out onto your Desktop. Rename the 3D icon to Icon1.icns and then rename the icon you want to use as Icon.icns. Note that the file name is case-sensitive. Now drag the renamed icons back into the Resources folder. You’ll have to click “Authenticate” and type your password in order to overwrite the existing files.
  4. The last thing to do is drag Twitter out of the Dock and relaunch the application. Your new/old icon should now show up, and all is right with the world again.

This method works with any application, not just Twitter. Just make sure that the icon you drag in has exactly the same name as the app’s existing icon, and you should be good to go.
