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.

The get info way doesn’t work unless you copy the icon before you upgrade the app, no? You can’t just copy & paste the .icns file. The image has to be copied from the info pane (not sure what kind of file that is, but you’d still have to find the image online somewhere). Even if you could do it this way you’re still 90% of the way to doing it the way described in the article. If I’m wrong, I’m wrong, but it seems the article is the easiest way.

No, you’re right. In order to be able to paste it into the Info window, you need to have the old icon in the first place. Since that icon is in the Resources folder anyway, you may as well use this method.


Is there a way to add an icon to a folder in the dock like the watermark on the Applications folder or Documents folder?


I use a combination of a couple of apps called Telling Folders and Iconverter to put icons on folders, although I’m not sure if you can get the watermark effect this way.


Not sure why you would go to the bother of modifying an application resource when you can just select the application, press command-i and then paste a new icon onto the one in the top-left hand corner of the info dialog…?


also , you can replace 2 to 4 steps by just pressing cmd+i, selecting the current icon on the information panel and pasting the new icon.

By the way CandyBar is a great program.


I use something called CandyBar to change not only my app’s icons but my folders and dock too.

It makes it super easy to customize the way your mac looks
