Apple Mac OS X manual Uid

12

You can’t change the names or IDs of system accounts. So when you migrate users and groups, don’t try to do so. However, you can add users during migration to two system groups—admin and wheel:

ÂWheel is a group that gives members almost as much control as root. If you’re a member of the wheel group, you can use the su (substitute user) command in the Terminal application to log in to a remote computer as the root user. Use ssh to log in, type su, then supply the root password when prompted.

ÂThe admin group gives members the right to administer Mac OS X Server. Admin users can use server management applications and install software that requires administrator privileges.

Here are the predefined user accounts:
