MacOS Ventura Upgrade for non-admin user

Apples vision for this is to use MDM Commands to run OS updates. Beyond giving your users volume ownership, you will not have a good time enabling and empowering users to run their own OS updates. This is absolutely something to submit feedback to Apple on.

Volume ownership

Mac computers with Apple silicon introduce the concept of volume ownership. Volume ownership in an organizational context isn’t tied to the true legal ownership or chain of custody of the Mac. Instead, volume ownership can loosely be defined as the user who first claimed a Mac by configuring it for their own use, along with any additional users. You must be a volume owner to make changes to the startup security policy for a specific install of macOS, authorize the installation of macOS software updates and upgrades, initiate an Erase All Content and Settings, and more. The startup security policy defines the restrictions around which versions of macOS can boot, as well as how and if third-party kernel extensions can be loaded or managed.

Hi @TechSpecialist 

Thanks for the script, works like a charm on Intel machines.  Does it work for M1 ? anything to edit?

@AJPinto I was told that volume Owners (m1) doesn't need admin rights to install Ventura if not restricted, is that true?

Yes, this should be reporte back. Not making things easy !!

As far as I understand, yes its true. 

here is a script that I combined using a few other users scripts its pretty simple it has 2 JAMF Paramteres $4 and $5

$4= input verison number ex: 13.4
$5= input just .app location /Applications/Install macOS Ventura.app

#!/bin/bash

softwareupdate --fetch-full-installer --full-installer-version "$4"

# This script will provide temporary admin #
# rights to a standard user right from self #
# service. First it will grab the username of #
# the logged in user, check if they are #
# already an administrator, and then either #
# skip the elevation or proceed accordingly. #
# Finally, it will create a launch daemon #
# that will count down from 10 minutes and #
# then run a secondary script to demote the #
# user back to a standard account. The launch #
# daemon will continue to count down no matter #
# how often the user logs out or restarts #
# their computer. #

Hello everyone,

We have standard Intel/M1 accounts (non-admin) (OS: 10.14.6 to 12.6.1).

Could you advise how best I can grant them admin access to make the upgrade ?

Thank you.
