Many apps have beautiful icons nowadays. Looking at my own dock, I’m surprisingly pleased by the app icons for Postbox, Spotify, Chrome, MacDown, FocusWriter, Discord, iBooks, and Xamarin Studio.
And then there are a handful of other apps that are ruining the simplistic beauty of my dock with their outdated and/or clashing icon designs.
One of the nice things about Mac is how easy it is to change any app’s icon to any image that you want. Other OSes let you do this too, of course, but Mac is special in how intuitive the process is and how few hoops you need to jump through.
Basically, take any image and open it in Preview. Once opened, click-and-drag your mouse to select the portion of the image that you want as the icon. (Hint: Hold Shift to keep the selection a square!) With the icon selected, go to Edit > Copy (or Command + C) to copy the image to your clipboard.
Now open Finder and navigate to your Applications folder. Right-click on the app you want to change and select Get Info in the menu. At the very top, click on the app’s current icon — once clicked, it will have a blue ring around it. Now hit Command + V to paste your image as the new icon.
