Depending on the version of iBoot installed, and which way the wind’s blowing, one of two failures can occur: What should happen before they’re installed is that macOS should ask for the primary admin user’s password, and installation should proceed.
CREATE MAC ADMIN ACCOUNT INSTALL
What happens, though, when a second admin user is created on that second system?īecause that second admin user has full admin rights, you’d expect them to be able to download and install macOS updates. When this works properly, it’s almost transparent to the Owner, and Ownership is handed over securely to the primary admin user of the second system.
CREATE MAC ADMIN ACCOUNT PASSWORD
If you agree to that, you’re prompted to enter the Owner’s password so their OIK can be accessed from the Secure Enclave.

When you run a macOS installer from the Owner account on internal storage, you’re normally invited to copy that Owner account to the second system, to become its primary admin user. For the M1’s Secure Boot, each bootable volume group needs a signed LocalPolicy which defines security policy for that system, and an Install User authorised by the Owner. On an Intel Mac, there’s little to the installation and use of second operating systems: format the disk, run the installer, and by the end of the process you can switch readily between the two, logging in as an appropriate user on the system of your choice.
CREATE MAC ADMIN ACCOUNT UPDATE
Last week, when trying to perform a macOS update on a second operating system on my M1 Mac mini, I only succeeded at the third attempt, after a total of five hours. And that’s where problems can occur, with a combination of puzzlement and frustration. If you install a second operating system, on internal or external storage, the Owner needs to agree to hand over Ownership to users of that second system. If your M1 is configured with a single macOS boot volume group on its internal SSD, never boots from an external disk, and has no other admin users – a vanilla system – then that’s all transparent. This is based on a private key generated in the Secure Enclave known as the Owner Identity Key (OIK).Įach M1 Mac has just a single OIK, and access to that is confined to that primary admin user of the internal SSD, who is thus its Owner. During that inital setup, the Mac sends a request to Apple for that Mac’s signed Owner Identity Certificate (OIC). Let me explain.Īccording to the small print in Apple’s Platform Security Guide, when you set up a new M1 Mac, or set one up after restoring it in DFU mode, the primary admin account created is special: it’s the Owner account of that Mac. Because now, in addition to regular users, admin users and root, there’s another class of admin user: the Owner. Don’t create that power if you’ve no particular need to wield it, and under no circumstances should you use the root account for day-to-day computing.In the next few days those using M1 Macs will be updating to Big Sur 11.5, blissfully ignorant of how, as an admin user, their Mac could refuse to update. The root user can access almost everything-at least, everything not protected by System Integrity Protection-which is a lot of power. Only enable root if you have a specific reason to, however.
CREATE MAC ADMIN ACCOUNT HOW TO
RELATED: How to Disable System Integrity Protection on a Mac (and Why You Shouldn't) Last year researchers discovered a bug that let anyone become the root user, and while that’s patched now, creating a root account yourself prevents anything similar from happening in the future. A root account can access everything.Īnd there’s another reason to enable the root account: security. You can’t make changes to other users’ files, for example, or even see most of them.
CREATE MAC ADMIN ACCOUNT SOFTWARE
This grants a level of permission required to do things like install software and change system settings, but it doesn’t give you permission to access everything.

If you’re the primary user of your Mac, odds are you use an administrator account. Want to enable the root account on your Mac? You can, but the functionality is a little buried in System Preferences.
