How do you create a Working Bootable External Backup -- going from intel to apple silicon
Looking for a great set of instruction to create a bootable backup of my 2019 MacBook Pro I can use on my M4 MacBook Pro and/or M4 Mac mini, just in case I ever need it.
I can wipe an external SSD, authorize it 🙄, install Mac OS Sequoia on it and use migration assistant to bring the users over. But, the passwords aren't brought over and who knows what else didn't make it, so it doesn't give me confidence to 'wipe the internal SSD
I can create a backup using Apple Software Restore that boots from the intel MacBook Pro, but not the M4. I get the message 'The version of macOS on the selected disk needs to be reinstalled. Reinstall macOS or select another startup disk.' Reinstalling macOS does not fix the problem, and when I do get it to ask for the prompt to authorize the external boot disk, it never takes and just stays in a loop of entering passwords.

Any help would be appreciated. This should be straightforward like functions. This is something I have always done, as it's a great way to not lose productivity should a machine die. Prefer to not use Time Machine or iCloud, as both come with their own set of issues and security problems.
Using the Terminal works.
Knowing what has changed / what steps I am missing may help.
Thanks in advance!
