System Configuration settings in System Image Utility on Mac
In the System Image Utility app on your Mac, use the System Configuration pane to specify how unique names and settings are assigned to each computer when you push a system image to a group of computers. You can use a configuration file to apply preconfigured names, generate new names from specific criteria, or a combination of both. Use the information below to determine what you need to provide for each of these methods.
Computer/Hostnames
If you want to use a configuration file to provide computer names, click Choose File and select a file. The configuration file must contain either MACAddress or HardwareUUID to identify the computers:
MACAddress: The Ethernet MAC address of each computer that is found in the Hardware tab of Advanced network settings in System Preferences, such as ab:cd:ef:12:34:56.
HardwareUUID: The unique UUID of the computer that is found in the Hardware overview section in the System Information app, such as 58C91DDB-8A8A-4509-BC67-6E65FAC453F5.
HostName: What you select as the host name for each Mac, such as macone.example.com.
ComputerName: What you select as the computer name for each Mac, such as Mac One. This name appears when you open the Sharing preferences pane.
BonjourName: What you select as the Bonjour name for each Mac, such as MacOne. This name appears when you click Edit in the Sharing preferences pane.
The following comma or tab-delimited file types are supported for use with computer naming: .csv, .numbers, and .rtf. Dictionary and Array .plist files are also supported.
Generate Names
If you don’t know the MAC address or hardware UUID of each computer, you can enter some text, like “Network Client,” in the Generate Names field, and System Image Utility will generate unique computer names using this text string. You can also combine this option with an import file. For example, you could enter the initials of your organization and have them prepend the names in the import file.
ByHost preferences
ByHost preferences are settings that are unique to each Mac. If you created an image from an existing Mac, you may want unique preferences to remain on each Mac that receives the image. To retain each computer’s ByHost preferences, select “Match to client after install.”
