Have you ever thought of changing the icon for an file, folder or app on your Mac? The icons of some apps may not suit your taste but you have to put it on the Dock or Desktop for quick access. In that case you can change the original icon with a new one you prefer to use. Some third party apps offer a quick way to manage Mac app icons, yet macOS also allows you to modify them in simple steps. Actually, it is quite simple to customize the icon which represent a file, folder, app or even disk.
If you are unfamiliar with it, read through this post to learn how to do the trick.
To get the new icon for replacement, you can either download the existing icon files (.icns) on available websites, or use your favorite images as new icons. Personally, I tend to search for ‘Mac icon files’ on the web and directly save the desired ones on my Mac, as an .icns file contains multiple sizes of an icon for various uses.
If you are planning to change a third party app, just do the following steps:
The new icon will instantly replace the original one in the Info window. During the process you may be required to enter an administrator password to save the change.
Alternatively, you can replace the app icon with a GIFPNG, JPEG or other image:
To restore the change, you just need to select the new icon, and choose Edit > Cut.
If the app has already on the Dock, the new icon may not show up until you log out. You can execute the “killall Dock” command in Terminal to fix this issue.
These methods also can be used to change the icons of a file, folder and volume on your Mac. Note that if you want to change some built-in apps like Calendar, Finder or Trash, you will need to disable the Security Integrity Protection before changing the icon by the aforementioned way.
