macOS Big Sur has brought a massive UI overhaul to the Mac. It added control center, a new notification center with redesigned widgets and much more. It also introduced a new icon design for apps. That’s fine, but the problem is that a lot of developers haven’t updated their app icons with this new design. This means that your Mac may seem inconsistent and rather strange. Fortunately, there is an easy fix. Here’s how to change all app icons to Big Sur style icons with Terminal on Mac.

How to Change App Icons to Big Sur Style Icons

There are many ways to change icons on a Mac. However, for an update as huge as Big Sur, changing app icons manually can be tedious, so we’re showing you an easier and faster way to do it.

We’ll also cover other ways to change app icons in macOS Big Sur, just in case you don’t want to use Terminal. You can use the table of contents below to jump to the method you want to try.

1. Change App Icons to Big Sur Style with Terminal

This first method requires some effort on your part, but it is completely free and changes almost all app icons to the new design. Here’s what you need to do.


You must have NodeJS installed on your Mac. If you don’t, you can download it from this link.

Once you have installed it, just check if the installation was successful correctly by running the following command in the Terminal application.

node -v

The terminal should show the version of NodeJS installed on your computer. If not, you need to reinstall NodeJS.

How to Change App Icons with Terminal

Now that we’ve finished installing NodeJS, let’s start fixing the app icons.

  • Launch Terminal and use the following command

cd ../..

  • Now use the following command to access the Applications folder on your Mac

cd Applications/

  • We will now install a Terminal application which will do the rest of our work for us. Just use the following command.

sudo npm i -g iconsur

  • Since we used ‘sudo’, you will be asked to enter your password. Just enter it. No characters will appear on the screen; It’s normal. Type your password and press the return/enter key.
  • You will see a progress bar displayed and iconur will begin to download and install on your system.
  • Once installed, simply use the following command to change the app icon to a Big Sur style icon. Replace “app name” with the name of the app for which you want to change the icon.

sudo icon set [app name]

  • For example, I want to change the icon of Microsoft Edge, so I will use the following command. That ” ” you see after “Microsoft” is an escape character. You will need to use it for applications that contain spaces, such as Microsoft Word, Microsoft Excel, etc.

sudo icon on set Microsoft

  • You will see a few lines of output on your terminal telling you what iconur is doing. Once everything is done, you will see something like “Icon set successfully for /Applications/Microsoft”.
  • Take a look at the before and after app icons for Microsoft Edge in Launchpad. As you can see, the new icon is more in line with Big Sur’s icon styles.

You can repeat the whole sudo icon on [app name] Terminal command for as many apps as you want.

To note: Icons may return after app updates. In such a case, just run the iconur command again.

2. Change app icons manually with Finder

If you don’t want to use Terminal for some reason, or if you just need to change the icon for a single app and iconsur seems overkill, you can also change icons with Finder. Here’s how.

To use this method, you’ll need to have the new icon you want to set saved on your Mac somewhere. I’m using the iOS app icon for Photoshop here.

  • In Finder, click “Applications” in the sidebar. If not, just press “Command + Shift + G”, type “/Applications/” and press the Return key to navigate to the Applications folder.
  • Right-click on the app whose icon you want to change. For this example, I’ll be using Adobe Photoshop because I haven’t updated Photoshop to the latest version yet. In the context menu, click on “Get information”.
  • Open the icon you downloaded in Preview. Press ctrl+A to select it and ctrl+C to copy it.
  • Now click on the app icon in the Get Info window and press ctrl+V. You will be prompted to enter your password at this point. Simply type it in and confirm the change.

That’s it, Photoshop is now using the new app icon I defined. You can do this for just about any app on your Mac.

3. Use Replacicon to change icons

If, unlike me, you don’t like playing in the Terminal app, you should check out Replacicon. This app automatically scans all apps installed on your Mac and searches for their icons on the web. You can then choose which icons to use to replace your old app icons.

The app is priced at $2.99 ​​so you will have to spend some money here. However, it takes the manual labor out of the job and makes it much easier.

Easily change app icons to Big Sur style icons

While I expect most major developers to update their Mac app icons to match Apple’s new design, it could take a while. So it’s a good idea to take matters into your own hands until that happens and change your app icons yourself. This way, your Mac will look cleaner and more cohesive.

We’ve included methods for people who don’t mind using Terminal, people who want to do the job manually, and even a paid option for those looking for a quick fix for all app icons.
