How to Change Your Mac's App Icons

If you're tired of how your Mac desktop looks, consider changing your app icons. It can be a fiddly process by default, but luckily, there are ways to make it easier. By using these methods, you can make your dock reflect your wallpaper's aesthetic, ensure that all app icons are the same size, or just replace ugly app icons with something better.

While you can easily find icons for various Mac apps with a quick web search, it's much easier to get them from a site dedicated to icons. One of my favorites is macOSicons.com, which lists over 25,000 alternative icons, meaning you should be able to find multiple options for popular apps with ease.

Changing Mac app icons using the built-in method

macOS allows you to change an app's icon manually, but it has one frustrating drawback. Getting started, however, is easy.

First, download or create an alternate icon, then open Finder and go to the Applications folder in the left pane. Select any app and press Command-I to open an Info pane. Now drag-and-drop the new app icon into the top-left corner of the Info pane. This will replace the app icon for you.

This method is fast and free, but annoyingly, your app will go back to using its default icon with every update.

You can also use one of two free apps to replace macOS app icons for you. These are IconChamp and Pictogram. Both show you a list of your Mac's installed apps and let you manually pick an alternative icon. As much as I want to recommend these options, both apps haven't been updated for years, so they don't always work reliably. For instance, IconChamp has a premium tier that supposedly lets you pay a one-time fee that unlocks the ability to change system app icons. However, the purchase page for this tier doesn't load and there's no way to buy it at time of writing. These free apps might work in a pinch, but if you want a more robust solution to changing app icons, consider paying for a better alternative.

That brings me to Replacicon, which costs $8 and is probably the best way to customize your Mac icons. Although $8 is steep for what is essentially a single-purpose app, Replacicon has a few features that may justify the cost for some people. The best one is that it installs a helper tool to monitor app updates and it retains your replaced icons even after apps are updated. This feature alone is enough to justify the purchase to those serious about macOS theming. 

Replacicon also has an easy-to-understand interface that provides a bunch of alternative app icons for each app installed on your Mac. Changing an app icon is as simple as clicking on one of the alternatives. To use an icon that's not listed as an alternative by default, you can also click the + button next to the list and choose one of three options: use a downloaded icon file, create an icon from any saved image on your Mac, and use Apple Intelligence to generate an app icon. All three options open a pop-up window, and once you've selected or generated an icon, the app will automatically add it to its list of icons and replace your existing icon for you. Not having to leave Replacicon to go looking for files is great, and it makes the process seamless.

To make your list of apps more manageable, Replacicon provides two filters. One of these lets you view only the apps that are currently in the Dock, and another highlights only apps that have legacy icons—from the time when macOS icons used to be of different shapes and sizes. Nowadays, macOS icons have adopted an iOS-style uniform size with rounded corners, and you can use the legacy icon filter to spot the icons in need of uniformity with the rest of the Dock.
