We are having to upgrade from Sierra to Mojave. We have been tasked with trying to do this with little to no user interaction. The tests that we have run have failed. It seems that the Mojave installer stalls out. Here is the current workflow.

My current workflow is to use JAMF to cache a .dmg containing the Install macOS Mojave.app and copy the .app to /Applications/ . Then an execute command runs that launches the startosinstall service contained in the .app using the flags –agreetolicense –nointeraction to automate the install. This has worked perfectly on several High Sierra test boxes I have, but on the three Sierra boxes I’ve tried it on, the service hangs with this error repeated: com.apple.install.osinstallersetupd: Service only ran for 0 seconds. Pushing respawn out by 10 seconds. This repeats at respawn every 10 seconds until manually forced to quit.

--eraseinstall only works with APFS volumes. Technically, you'd have to upgrade to High Sierra first.

If I remember, 10.13.4 (or.6) is the min. OS for the startosinstall flag to function.

This is the script I wrote to do this, not had it fail yet, but cant be 100% if i have tested it in the specific set of circumstances you have, but I am fairly sure i did.

I have Multiple Policies that call it that just parse different values to the 2 Variables depending on the OS I want and if we want an upgrade or a clean build.

Hope this Helps you
