  1. Insert a 16GB+ USB drive.
  2. Open Terminal and run: 
    sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB

  • Fixes a Wi-Fi connectivity bug
  • Resolves iCloud Drive file syncing errors
  • Patches a graphics issue affecting the 2020 iMac (Radeon Pro 5700 XT)

Creating a Bootable USB Installer from the DMG

A raw DMG file isn’t directly bootable. You need to create a bootable USB drive for clean installations.

What you need: A 16GB+ USB drive (named "MyVolume").

Step 1: Mount the SharedSupport.dmg you extracted earlier.

Step 2: In Terminal, run:

sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

Step 3: Type y and press Enter. The process will erase the drive and write the installer.

    • Apple sometimes provides installers or links to the full macOS installer apps on its support site.
  3. Create an installer from the App Store “Install macOS Catalina” app on a Mac that supports it, then use the Terminal createinstallmedia command to build a bootable USB.
