Create NetRestore images in System Image Utility on Mac
A NetRestore network image allows you start up a Mac and quickly replace the entire contents of the internal startup volume. This type of network image can be based on a Mac that’s already configured with preferences, settings, and apps, and is ready to use, or one that starts up into macOS Setup Assistant.
Workflows that create custom NetRestore network images can use a bootable volume, a disk image (of a bootable volume), or a macOS install app as their source. For example, if you create a NetRestore network image of a Mac and at some point the internal storage device on the Mac fails, you can use the image you created to restore the volume on a new internal storage device.
