Building Vanilla Image

First, create a ventura-vanilla VM from the latest available IPSW with following command:

tart create --from-ipsw=latest --disk-size=25 ventura-vanilla

Start the VM and use UI to change some settings:

tart run ventura-vanilla

1. Disable Lock Screen and Screen Saver. Preferences -> Lock Screen -> disable first three settings.
2. Enable Auto-Login. Users & Groups -> Automatic log in as... -> admin.
3. Allow SSH. General -> Sharing -> Remote Login & Screen Sharing
4. Display -> Advanced -> Prevent from sleeping
5. Open Safari. Preferences -> Advanced -> Show Developer menu. Develop -> Allow Remote Automation.
6. (Optional, depends on your needs) Disable SIP. Run tart run --recovery ventura-vanilla -> Options -> Utilities menu -> Terminal -> csrutil disable.
7. Enable passwordless sudo:
   1. Run sudo visudo /private/etc/sudoers.d/admin-passwordless in Terminal.
   2. Add admin ALL = (ALL) NOPASSWD: ALL to allow sudo without a password.
   3. :wq to write the file and quit.
   4. sudo some command to verify no password is needed.

Shutdown macOS.
