Restor

Restor is a user-friendly application to (mass) image macOS computers from a single source. It is an application intended to be run interactively on a machine.

You can attach the machine-to-be-imaged via Thunderbolt or USB to the machine running Restor.

Restor will cache an image once it has been downloaded for future use, and will validate the image via SHA256. Only if the signature has changed, will the image be downloaded again.

Example Configuration

Restor has two configurable features: ConfigURL and CustomImage.

ConfigURL

Required

Set the ConfigURL preference to point at a plist containing the images to be used.

sudo defaults write /Library/Preferences/com.google.corp.restor.plist ConfigURL "http://server/images.plist"

The following format for the plist is required:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Images</key>
	<array>
		<dict>
			<key>Name</key>
			<string>Sierra (10.12) All Models</string>
			<key>URL</key>
			<string>http://server/10.12.6.dmg</string>
			<key>SHA-256</key>
			<string>ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff</string>
		</dict>
	</array>
</dict>
</plist>

CustomImage

Optional

Set the CustomImage preference to toggle the use of a local custom image.

sudo defaults write /Library/Preferences/com.google.corp.restor.plist CustomImage -bool true

10.13 and APFS Note

In order to restore an APFS 10.13 DMG to a machine, the host machine running Restor must also be upgraded to High Sierra 10.13. Otherwise, you will receive an error when attempting to image the machine.
