Install macOS

• This app is either available:
• In user space (downloaded from the App Store)

• In Recovery mode (the same installer version as your current macos installation)

• The installer will ask in which volume you want to install the system

• Can be used to reinstall the current macOS installation
• Can be used to install a new system as a secondary macOS installation (dual boot) in a new volume

Bootable Installer

• You can create a bootable USB drive from the MacOS installer

/Aplications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUsbDrive

• The Bootable Installer can then be launched from iBoot

MDM bypass

• As soon as the installation completes and the first setup appear, exit it (Command+Q) and boot into Recovery
• Once in Recovery, mount the Data partition

Recovery

# Block MDM server connection
echo "0.0.0.0 iprofiles.apple.com" >> '/Volumes/Vaporwave - Data/private/etc/hosts'

# Skip the user setup
touch '/Volumes/Vaporwave - Data/private/var/db/.AppleSetupDone'

# Enable the root user and define a password for it
node_database='/Volumes/Vaporwave - Data/private/var/db/dslocal/nodes/Default'
dscl -f "$node_database" localhost -passwd "/Local/Default/Users/root"

Root user

• Start the system and log in with the root account

# Create your user
sysadminctl -addUser myself -admin -password - -adminUser root -adminPassword -

# Enable secure token for the new user (necessary for FileVault)
sysadminctl -secureTokenOn myself -password - -adminUser root -adminPassword -

Conventional User

# Disable the root account
dsenableroot -d

# /etc/fstab
LABEL=Macintosh\040HD none auto noauto
