Usuario root mac os x
The root user can do many things an ordinary user cannot, such as changing the ownership of files and binding to network ports numbered below The name root may have originated because root is the only user account with permission to modify the root directory of a Unix system. It spawns all other processes directly or indirectly, which inherit their parents' privileges. Only a process running as root is allowed to change its user ID to that of another user; once it's done so, there is no way back.
Doing so is sometimes called dropping root privileges and is often done as a security measure to limit the damage from possible contamination of the process. Another case is login and other programs that ask users for credentials and in case of successful authentication allow them to run programs with privileges of their accounts. It is often recommended that no-one use root as their normal user account,   since simple typographical errors in entering commands can cause major damage to the system.
Instead, a normal user account should be used, and then either the su substitute user or sudo substitute user do command is used. For a number of reasons, the sudo approach is now generally preferred — for example it leaves an audit trail of who has used the command and what administrative operations they performed.

Some OSes, such as macOS and some Linux distributions most notably Ubuntu  , automatically give the initial user created the ability to run as root via sudo — but configure this to ask them for their password before doing administrative actions. In some cases the actual root account is disabled by default, so it can't be directly used. In a few systems, such as Plan 9 , there is no superuser at all.
A Windows administrator account is not an exact analogue of the Unix root account — Administrator, the built-in administrator account, and a user administrator account have the same level of privileges. The default user account created in Windows systems is an administrator account. This is for advanced users only. Be sure to set a strong password for the root account. With root now enabled, the account can be used freely. The root account can access, read, and write to all files on a system, even if they belong to someone else.

Additionally, root can also remove or replace system files. The Directory Utility control panel can also be used to change a set root password through the Edit menu, or that can be done through the command line using sudo passwd, similar to changing the root password in iOS devices.

Name required. I have found it very interesting because I am in the process of testing FileVault 2 on We are using JSS 9. We do not create any other account at all. This has just been tested on a brand new MacBook Pro about 3 hrs ago. I hope this helps………! FileVault 2 is enabled for that user. Pretty nifty…even if it involves an additional step in our Thin Provisioning process, works fine. If anyone has any ideas I am all ears — would really appreciate any help! I can log in as the hidden local admin, and I can log in as an AD user, which creates a mobile account on login.

Same thing also true when I logged in with an AD account and creating the mobile account — same results as before. Am I the only one baffled by the Test 2 result? Will post over the long weekend to try and help other folks out. Sorry for the suspense. It appears that, at least with After deploying and then going through the manual Setup Assistant process, the freshly minted admin user account was still NOT SecureToken enabled. I was very unpleasantly surprised. I ran some queries following that attempt — and it turned out that one of our software installers for a security product was creating a user as part of its installation.

So, in…. Attempt 2: Performed a much simpler Deployment. I continued to leave the DS account creation and setup assistant suppression off, but also stripped the workflow down. I basically left all of the OS configuration items AD binding, Profile manager enrollment, some environment-specific network scripts, etc.
After this deployment, upon startup, I was directed to the setup assistant, and manually created the first user at the console. When I queried the system, the user was in fact SecureToken enabled — and that allowed me to use that account to enable others, including AD accounts, using the sysadminctl commands. It is definitely time to replace DeployStudio with other tools that are being maintained to use the newer methods for these critical processes. Will validate this on TouchBar units next week.
FileVault master keychain appears to be installed. AD Binding, network config, profile manager enrollment, software installations…all handled in the DS workflow.

The important bit is that this user gets created before real humans get to try and log in. That account was created the first time that Mr. Where in the process?
The important thing to call out here is this, from the above:. I have adjusted my DS deployment process as a stopgap before retiring DS to skip the Master restore part of the process; this instead relies on a separate OS install that happens prior to DS. I have outlined that in some more detail in a separate comment on this thread.
Enable the “root” user using Single User Mode in Mac OS X
Hope this helps. Have you run into an issue where the only local admin account does not have a secure token? FileVault is enabled and the user is able to login on the FV login screen. We were unable to issue a new recovery key manually or using a script that worked with other users. I read that disabling FV and then re-enabling should help but sudo fdesetup disable produced an error:.
I was running into the issue where the only account on my machine was the management account laid down with the Jamf PreStage Enrollment. This account did NOT have a secureToken with Again, only a single account. Run sudo as the management account, try to enable the management account for a secureToken using the management account as the admin user. It worked for me. I had to enter the same password 3 times for the different needs, but it worked.
I think this just showed that the management account was in some way in a FileVault deferred status. Anyway, with Hi I have a You can select bypass but would prefer we dont get this prompt in the first place for non filevaulted machines. Try this to supress the dialog..
