here you go
Enrolled via DEP: No
MDM enrollment: No
The screens for MDM enrollment never showed up because I completely bypassed it thru the first computer. Yes, it does require another M1 computer that' Non-DEP but that process is just once to build the External SSD OS once.
I did find some videos about disabling wifi, login, enable wifi, download some software (is that sofware safe? Something about Checkm8) but I don't want to install software - I'm sure it's fine since people are using it but I don't want to run csrutil either, terminal etc.
Anyway, I felt it was too much babysitting the process so I rather just instal lit twice with my method cuz I can just go to sleep after part 1 started and just do part 2 and set it and forget it.
Much easier and requires no real attention to watch it install.
And the benefit of my method is that my external SSD can be updated with latest software so any new Macs I install would have all of the software I normally want on it. Visual Studio code, nodejs, docker etc. It's an "golden image" for my own base build!
Glad I was able to contribute to this new method! I've been using the csrutil editing hosts tricks for many years. Frustrated a long time that I cannot do the same on M1 and Carbon Copy and SuperDuper are all failing also. My method can also help you dupe an working mac completely if you ever say upgrade to a new computer and co not want to reset- everything from scratch. I don't think Migration Assistant will migrate stuff I installed manually via GIT etc in various directories so I rather just copy it all as is in the future.
