Change App Icon on MacOS Big Sur: A Step-by-Step Guide

Are you tired of using the default app icon on your Mac? Do you want to add a personal touch to your desktop or dock with a custom icon? In this article, we will guide you through the process of changing the app icon on MacOS Big Sur.

Before we begin, it's essential to note that the steps below are only applicable for MacOS Big Sur. If you're using an earlier version of macOS, please refer to our previous tutorial on how to change app icons on older versions of macOS.

Phase 3: The Black Screen with Apple Logo and Progress Bar

The first phase involves booting your Mac into recovery mode. To do this, press the power button while holding down the Option (⌥) key. This will bring up a menu with several options, including 'Recovery Mode'. Select this option and wait for your Mac to boot into recovery mode.

Once you're in recovery mode, you'll see a black screen with an Apple logo and a progress bar. Proceed as normal and let the process complete.

Phase 2: Black Screen with Apple Logo and Progress Bar (Time Remaining)

The second phase is similar to the first phase, but this time, you'll also be prompted to enter your Time Machine backup password. Enter the password correctly, and proceed as normal.

After the black screen disappears, you'll see a menu with several options, including 'Disk Utility'. Select this option and create a new partition for your macOS installation.

Phase 1: Big Sur Background

The third phase involves booting into the Big Sur USB installer. To do this, insert the Big Sur USB installer into your Mac, restart it while holding down the Option (⌥) key, and select the USB drive from the startup menu.

Once you're in the Big Sur USB installer, open the Terminal app and enter the following command: `csrutil disable`. This will disable System Integrity Protection, which is essential for changing the app icon.

Reboot your Mac into the BS installer USB by selecting 'Reboot' from the menu. Once it reboots, you'll see a black screen with an Apple logo and a progress bar.

Preventing Snapshot Volume Sealing

When installing Big Sur, you may encounter a message stating that your snapshot volume is sealed. This means that the installation process has automatically created a snapshot of your current system configuration. To prevent this from happening, you can use the following command in the Terminal app:

`csrutil authenticated-root disable`

This will disable authenticated root access, which is required for creating snapshots.

Changing the app icon on MacOS Big Sur may seem like a daunting task, but with these steps, it's easier than ever. By following this guide, you'll be able to customize your app icons and add a personal touch to your desktop or dock. Remember to always back up your data before making any changes to your system configuration.
