Create and configure mobile accounts on Mac
A mobile account lets you access your server-based network user account remotely. You use your network account user name and password to log in, whether or not you’re connected to the network.
Before you start, ask your network account server administrator to set up a mobile user account for you.
Log in to your Mac using your network user account.
In the login window, enter your network account name and password. If the login window displays a list of users, click Other, then enter your network account name and password.
Choose Apple menu > System Preferences, then click Users & Groups.
Click the lock icon to unlock it.
Enter an administrator name and password.
Click the Create button next to “Mobile account,” choose the disk where you want to store your local home folder, then click Create.
If the login window displays a list of users, your mobile account name is included in the list, and you can click it to log in (you don’t need to click Other, and then enter your account name). You set the login window to display a list of users in Users & Groups Login Options preferences.
