I work at a College to where we receive in anywhere between 400 - 2000 systems back after fall then spring semesters. We were using Mac Provisioner to Erase and reload all of our returns to Catalina (T2 chips requiring to first boot using Command, R to get to utilities and then running command line in terminal). Now with Big Sur this does not seem to work. Any other suggestions for mass loading this many returns as running thru Jamf requires logging into all systems then running downloads to Big Sur and running the erase and reinstall commands which I do have setup in Self Service.. just trying to avoid booting and logging in and downloading.
Has anyone had issues with Mac Provisioner running via terminal in internet recovery? I just downloaded the latest version of MP and created a fresh Catalina USB stick. Everything worked as expected on 1 machine coming from Mojave, but I've tried with several different USB drives and computers running Catalina (launched from terminal via internet recovery), and it consistently locks up on "Preparing to run macOS Installer...". It never proceeds.
I also found that using MP3 to install 11.0 only works on Macs running 10.15 or 11.0. If running an older OS then MP3 fails to verify network connectivity.
High Sierra & MP3-BigSur = No (network error)
High Sierra & MP3-Catalina = Yes
Mojave & MP3-BigSur = No (network error)
Mojave & MP3-Catalina = Yes
Catalina & MP3-BigSur = Yes
Catalina & MP3-Catalina = Yes
Big Sur & MP3-BigSur = Yes
Big Sur & MP3-Catalina = No (hangs preparing to run installer)
I tried manually erasing the disk and it didn't work. When running MP3 it gets past the erasing disk step and hangs on the later preparing installer step. Must be incompatible environment similar to the network error.
Somehow I can’t even create a Big Sur startup disk with MP-3. The app gets stucked in various states (while erasing or writing files) but is never finishing the process?
Trying to create the disk on a 11.4 system.
Ooh I'm going to have to look into this - wish I'd heard about Mac Provisioner sooner!
@brussell Haven't used Mac Provisioner to downgrade 16" T2 MacBook Pros but manually we have to start them up with Big Sur and create the first account somehow, then reboot into Recovery and run Startup Security to reduce to Medium Security the Secure Boot settings and allow booting from External Media. If MP can do that then it will save my organization considerable time! Otherwise, we'll be looking at MDS.
I have noticed that the recovery environment effects if it works or not. As others have noted trying to use a stick to upgrade Mojave to Big Sur, just hangs or gives network errors.
I don't like the new version of MP as the behaviour has changed... When doing a restore it installs components on the existing macOS install. Boots to macOS, login as new service account and auto runs macOS installer.
We ended up moving away from MP and back to MDS (Mac Deploy Stick). It works great, similar to the old version of MP. Also we have a single MDS boot drive with workflows for both Big Sur and Monterey.
