macOS installer script not working for Apple Silicon M1 Macbook + macOS Monterey

Hi all,

  Referring to this macOS installer script.

macOSUpgrade/macOSUpgrade.sh at master Β· kc9wwh/macOSUpgrade Β· GitHub

  This script works fine for Intel Macbook upgrading to macOS Monterey 12.0.1.

  But it does not work with Apple Silicon Macbook 😞

  When attempting, I get the following error:

Spoiler
Error: failed to authorize for installation. Provide a password with --stdinpass or --passprompt.
By using the agreetolicense option, you are agreeing that you have run this tool with the license only option and have read and agreed to the terms.
If you do not agree, press CTRL-C and cancel this process immediately.

Investigating further, I run the following in a M1 Mabook's terminal.

Spoiler

/Applications/Install\ macOS\ Monterey.app/Contents/Resources/startosinstall --agreetolicense --nointeraction --forcequitapps
Error: A method of password entry is required.
Usage: startosinstall

.....

The error suggests I need to supply admin username and password via 
--user, an admin user to authorize installation.
--passprompt, collect a password for authorization with an interactive prompt.
--stdinpass, collect a password from stdin without interaction.

 

I want JAMF to execute this. I DO NOT want to need to supply admin account and password.

Anyone got any suggestions?

Hi there,

I managed to get the upgrade to Monterey running on an M1 macbook via Self Service with the help of a script from https://github.com/therealmacjeezy/Scripts/tree/master/macOS%2010.14%20Update%20Script, it was originally created for upgrading to Mojave but I made some adaptations to get it running for Monterey.

You will need to create the installer package and have it within the self service policy, the install macOS Monterey.app has to be available for the script to work.  Got it here: https://scriptingosx.com/2021/10/download-full-installer-update/

Most important - the logged in user has to have a secure token. This user does not necessarily have to be an admin.

this is the main key that triggers upgrade.

echo $fvPass | ./startosinstall --agreetolicense --forcequitapps --nointeraction --user $currUser --stdinpass

Actually I wasn't patient enough. Works like a charm!

I'm getting following error in /var/log/startosinstall.log while trying to upgrade an M1 pro 16" macbook.

Error: could not get authorization...

By using the agreetolicense option, you are agreeing that you have run this tool with the license only option and have read and agreed to the terms

I would test and use this process:  https://github.com/grahampugh/erase-install 

It is really robust and deployable but I would test it for your environment. 

Thank you.

Thanks, I will definitely start testing that.  The process I was testing just worked without me doing anything.  It doesn't seem to be 100% working so having another process is great.  Thanks again I'll give that one a shot.

Mentioned this above too. It’s the only proven solution that I’ve made work, and it’s very intuitive and a time-saver.
