The User & Drives tab is used to provides the following options:

In such a scenario, if you lose connectivity to the network or the Internet, you can Freeze or Thaw Mac computers using the following command line options: DFXPSWD=password deepfreeze -u username -p bootThawed --force DFXPSWD=password deepfreeze -u username -p bootFrozen --force |
Drives
• Specify the drives to be Thawed on your Mac. Enter the name of the drive and click Add Drive.
Maintenance Tab
The Maintenance tab is used to schedule a Maintenance Period when the computer will be automatically Thawed to allow Apple Software Updates to be permanently applied. The computer must be Frozen for the Maintenance schedule to start.
To create multiple individually named Maintenance Schedules, complete the following steps:
1. On the Maintenance Tab, click Add.
2. The Add Schedule dialog is displayed. Specify or select the following:
> Name – the default is Schedule 1. You can modify the name or leave it as it is.
> Days – select one or more days by clicking Mon to Sun.
> Start – select the start time.
> End – select the end time.
> Select Install Apple Software Updates to install any available Apple Software Updates.
> Run script – select this option and specify the name of the script.
 | Scripts must be present at /Library/Application Support/Faronics/Deep Freeze/Scripts on all computers. You can copy the script files manually or use a remote access tool to copy the scripts to all computers. |
> Select Lock Out User to prevent a user from accessing the computer during the Maintenance Period.
> Select Shutdown After Maintenance to shut the computer down after the Maintenance Period is complete.
> Select Show message x minutes before maintenance starts to provide a message to users warning them that the computer will be taken over at a specified time, and enter the warning time in the field provided. Use the text box to enter a custom message for the user, explaining that the Maintenance Schedule will take place at a specified time; by inserting %d as a variable into the message, Deep Freeze will automatically display the number of minutes until the Maintenance Period begins. (Again, %d is a variable corresponding to the number of minutes between the current time and the time that scheduled Maintenance will begin.)
 | The minimum time allowed for a Maintenance Period is 10 minutes. There is a minimum 10-minute interval required between schedules. Ensure sufficient time for the maintenance activity to complete. Insufficient time will lead to the failure of the update. |
3. To save any changes made, click OK.
