Change Restore preferences in System Image Utility on Mac
Use Restore preferences in System Image Utility to change options for Apple Software Restore restores and NetRestore network images.
To change these preferences in the System Image Utility app on your Mac, choose System Image Utility > Preferences, then click Restore.
Block copy the source volume
Performs a block-level copy of the source volume.
Don’t reorder for multicast streaming
When doing an image scan, you can choose not to reorder the blocks. Doing so may slow multicast streaming restores.
Retain the original volume name
Keeps the original volume name unless overridden in the NetRestore image from a macOS install app workflow.
Countdown timer before automated restore
Displays an alert that remains visible for 30 seconds, allowing a user to cancel an automated restore. For example, if the user mistakenly booted a Mac for automated restore, this option gives them 30 seconds to cancel before the process begins.
