Hi All,
I thought i would share with the community my method for deploying High Sierra with Casper Imaging.
The method basically consists for two scripts.
I have tested this with a 10.13.1 Netboot Image created with AutoDMG and AutoCasperNBI
restoreMacOS.sh To deploy the correct image which runs as a "before" script
imagingPostinstall. To run after reboot to run the Sierra Upgrade if needed.
The first script will decide which image to deploy to the Mac based on the currently installed Operating System or File system.
-If it is APFS it will deploy the 10.13.1 APFS image to the APFS container.
-If it is HFS+ it will check the currently installed OS. If the OS is already 10.13 it will image using the 10.13 HFS+ image.
-If the filesystem is HFS+ and the current OS is not 10.13 it will deploy 10.12.6 and then upgrade to 10.13 on next reboot using startOSInstall.
Script 1 RestoreMacOS.sh This replaces your base image in your Casper Admin Config
