Unlike a T2 Mac, M1 Macs don’t set one boot security policy for the Mac, but a policy for each bootable disk. If you’ve updated a bootable disk to the current version of macOS, change its boot policy back to Full Security. Use Reduced Security to update bootable external disks, and to maintain older bootable versions of macOS. If you’re unable to boot from a bootable disk using an older (non-current) version of macOS, change its boot policy to Reduced Security and it should then become bootable again. You may be prompted to assign an authorised user to that external disk, only to be informed that the version of macOS on that disk isn’t bootable and needs to be replaced. One of the stumbling blocks to using an external boot disk with an M1 Mac is that it may not cope if you update macOS on the internal SSD, then try booting from the external disk to update that. ![]() Booting an M1 Mac From an External Disk With Monterey ![]()
