Having a bootable USB drive is especially useful for troubleshooting and reinstalling macOS without needing an internet connection.

Step 1: Gather Required Materials

Before you start, ensure you have the following items ready:

  • A USB flash drive with at least 16GB of storage capacity.
  • A Mac computer running macOS.
  • The macOS Monterey installer, which can be downloaded from the App Store or via Apple's support page.

Step 2: Format the USB Drive

You need to format the USB drive to prepare it for the macOS installation files.

  1. Insert the USB flash drive into your Mac.
  2. Open Disk Utility (found in Applications > Utilities).
  3. In Disk Utility, select your USB drive from the list on the left.
  4. Click on Erase at the top.
  5. Choose the following settings:
    • Name: MyVolume (you can use a different name, but you'll need to adjust it in the command later)
    • Format: Mac OS Extended (Journaled)
    • Scheme: GUID Partition Map
  6. Click Erase to format the drive.

  3. Press Enter and you will be prompted to enter your administrator password.

  4. Confirm that you want to erase the USB drive by typing "Y" and pressing Enter.
