When attempting to install through a JAMF POlicy I get this error at reboot:

macOS could not be installed on your computer

Volume contains macOS or OS X Installation Media. Quit the installer to restart your computer and try again.

There is no installation media on the test device. I'm very confused.

Are you booting to "current startup disk" with your reboot options or "OS X Install Media"? If its the second that doesn't work right now as the name has changed. Booting to "current startup disk" will fix it.


I'm also coming across this issue—which is odd since I've been using the same package for it for a while now.

Tried switching the boot options in the policy but not having any luck.


Its long past time for Jamf to add "macOS Install Media" to the reboot options.


Figured this out.

Ran a Composer snapshot to see what gets installed during the pre-install process before the machine boots to the installer.

Deleting these guys did the trick:

#!/bin/bash

rm /AppleDiagnostics*
rm /BaseSystem*
rm -R /Packages

@jbourdon This worked for me. Thank you!
