How to change app icon on Mac

Much like Windows users, even Mac OS X users can change program icons of their apps. It's not hard at all, and we will explain it in few steps in this short article.

The very first thing you will need is an icon archive used by OS X (*.icns file extension). ICNS file stores a sort of icons in 16x16, 32x32, 48x48, 128x128, 256x256, 512x512 and 1024x1024 pixel resolutions typically in Portable Network Graphics (PNG) picture image file format. You can get them on Internet from sources like SoftIcons.

When you have have downloaded a new *.icns archive, go to the Applications folder, or to folder where the app is stored → right click on app → Get Info option (also you can click on app and use Command+I short cut).

OS X Get Info option

With this, OS X will show you info about the selected app.

Now drag the *.icns file and drop it on the icon visualized in the upper left corner of the Get Info window.
