Using 10.3, I was not able to use passwd while in single user mode. Likewise, all of the netinfo command line utilities would just hang. I ended up using sudo to change the root password. Note that this only works if a user account is setup to automatically log in, and is only necessary if you don't know the root password or a user password.

Update 11/29/2017 9:47 AM California time: Apple patched the flaw on Wednesday morning. Installing the patch immediately is the best way for Mac users to protect themselves and supersedes any mitigation advice. What follows is the story as written before the patch was available.
- Nov 28, 2017 Updated A trivial-to-exploit flaw in macOS High Sierra, aka macOS 10.13, allows users to gain admin rights, or log in as root, without a password. The security bug can be triggered via the authentication dialog box in Apple's operating system, which prompts you for an administrator's username and password when you need to do stuff like configure privacy and network settings.
- Once you've installed MySQL, you'll need to establish the 'root' password. If you don't establish a root password, then, well, there is no root password, and you don't need a password to log in. So, that being said, you need to establish a root password. Using terminal enter the following: Installation: Set root user password.
In one of Apple's biggest security blunders in years, a bug in macOS High Sierra allows untrusted users to gain unfettered administrative control without any password. https://vesiven.hatenablog.com/entry/2020/11/22/091814.
The bypass works by putting the word 'root' (without the quotes) in the user name field of a login window, moving the cursor into the password field, and then hitting enter button with the password field empty. With that—after a few tries in some cases—the latest version of Apple's operating system logs the user in with root privileges. Ars reporters were able to replicate the behavior multiple times on three Macs. The flaw isn't present on previous macOS versions.
The password bypass can be exploited in a variety of ways, depending on the way the targeted Mac has been set up. When full-disk encryption is turned off, an untrusted user can turn on a Mac that's fully powered down and log in as root. Exploiting the vulnerability was also not possible when a Mac was turned on and the screen was password protected. Even on Macs that have filevault turned on, the bypass can also be used to make unauthorized changes to the Mac System Preferences (including disabling filevault), or the bypass can be used to log in as root after logging out of an existing account but not turning off the machine. The behavior observed in Ars tests and reported on social media was extremely inconsistent, so results are likely to vary widely.
The upshot of all of this: as long as someone has filevault turned on, their files are most likely safe from this exploit as long as their Mac is turned off before an attacker gets hold of it. Locking a screen with a password also appeared to protect a computer while it's unattended.
Privilege escalation
Of more concern is that malicious hackers can exploit this vulnerability to give their malware unfettered control over the computer and OS. Such escalation-of-privilege exploits have become increasingly valuable over the past decade as a way to defeat modern OS defenses. A key protection found in virtually all OSes is to restrict the privileges given to running software. As a result, even when attackers succeed in executing malicious code, they're unable to get the malware permanently installed or to access sensitive parts of the OS.
'This looks like something that a piece of malware or an attacker could use in a multistage attack,' Patrick Wardle, a researcher with security firm Synack, told Ars. In cases such as these, attackers use one exploit to run their malicious code and a second exploit to escalate the privileges of that code so it can perform actions that the OS normally wouldn't allow. 'This appears to be one way malware or an attacker would be able to do that.'

Amit Serper, principal security researcher at Cybereason, said his tests showed the vulnerability is located in com.apple.loginwindow, a macOS component that's one of at least two ways users can log into accounts. He said he was unable to reproduce the exploit using a Mac's terminal window, although he said he saw reports on Twitter from other people who said the bypass worked using the terminal window as well. Whatever the case, he agreed with Wardle that the flaw likely represents a major privilege-escalation vulnerability that can be exploited easily by malware developers.
'If they're using API (programming interface) calls, it's a matter of writing the appropriate code,' Serper told Ars. 'An attacker should be able to trigger it.'
The vulnerability can also have dire consequences for people who have made their Macs accessible through remote management screen sharing provided through macOS or third-party services. Will Dormann, a vulerability analyst at CERT, said on Twitter that having remote options turned on will allow attackers to remotely access the machine with no password required. Results from a quick search that were posted on Twitter showed more than 105,000 Macs alone had the VNC remote desktop app installed. To check if remote management or screen sharing is on, users can check the Sharing menu in System Preferences.
The bug came to light Tuesday morning when a Mac user contacted Apple support representatives over Twitter:
Dear @AppleSupport, we noticed a *HUGE* security issue at MacOS High Sierra. Anyone can login as 'root' with empty password after clicking on login button several times. Are you aware of it @Apple?

Remember goto fail?
A vulnerability that logs users in as root without requiring any password at all is extraordinary, both because of the lack of testing it suggests on the part of Apple developers and the potential harm it presents to end users. The last time in recent memory Apple made an error of this magnitude was the so-called goto fail bug that gave attackers an easy way to bypass TLS encryption. It took Apple four days to patch the critical flaw, which got its name from one of the lines of code responsible for the vulnerability.Download netflix to computer mac. Apple representatives issued the following statement:
We are working on a software update to address this issue. In the meantime, setting a root password prevents unauthorized access to your Mac. To enable the Root User and set a password, please follow the instructions here: https://support.apple.com/en-us/HT204012. If a Root User is already enabled, to ensure a blank password is not set, please follow the instructions from the 'Change the root password' section.
Specifically, users should do the following:
- open the Users & Account menu in System Prefereces
- click the padlock at the bottom and enter an administrator name and password
- click Login Options
- Click Join (or Edit)
- Click Open Directory Utility
- Click the padlock at the bottom and enter an administrator name and password
- From the menu bar in Directory Utility, choose Edit > Change password
- Enter a strong password
The most important part for now is not to disable the root account. That only allows the root account to be re-enabled by putting 'root' in a user name field and leaving the password blank. Until Apple issues a patch, people should secure the root account with a strong password and leave the account enabled. As always, passwords should be at least 13 characters long, randomly generated, and contain a mixture of numbers, upper- and lower-case letters, and symbols. As an added layer of security, users should also ensure they have filevault turned on.
Some researchers are speculating unsecured root account doesn't exist until someone with physical access to the Mac attempts to log in while leaving the password blank. That has prompted advice Mac users not test their systems lest they create a persistent root user account that wasn't there previously. Other researchers report here and here being able to exploit the weakness to remotely log into a Mac, with no previous local login attempts.
This post was updated extensively over several hours as new details became available.
More than four years ago, Alicia Katz Pollock wrote “Five Ways to Reset a Lost Administrator Password” (17 January 2014), and through the vagaries of Google’s search algorithm, it remains our most popular article to this day. Apparently, lots of people forget their macOS passwords or need to help friends or clients who have lost their passwords.
Unfortunately, that article is long past its shelf life, so here’s a current guide to resetting an admin password in macOS 10.13 High Sierra. As before, you can accomplish this task in a variety of ways, depending on how the Mac in question was set up and what information you know.
Reset the Password from Another Admin Account
The best-case scenario is that there is another admin account on the Mac for which the password is available. If that’s true, you can log into that account and change the password for the locked account:
- Open System Preferences > Users & Groups.
- Select the locked account in the list at the left. (If necessary, click the lock at the bottom of the window and provide your admin credentials.)
- Click Reset Password.
- Enter the new password, verify it, and (optionally) include a password hint.
- Click Change Password.
The only problem with this method is if the locked-out account is logged in, you can’t modify it. The easy solution is to restart the Mac, log in with the admin account whose password you do know, and carry on from there. To forcibly log out the other user while rebooting, you have to enter an admin username and password.

If you don’t currently have an extra admin account on the Macs you take care of, it’s a good idea to create one. Just make sure it has a strong password that you’ll remember.
Reset the Password Using an Apple ID
What if there is no other admin account available? You can use the Apple ID associated with the account in question to reset the admin password, but only if these conditions are true:
- You know the Apple ID’s email address and password. If you don’t know the password, but you have access to the email address, you can reset the password at Apple’s Apple ID page.
- The “Allow user to reset password using Apple ID” checkbox in System Preferences > Users & Groups must be selected. This setting won’t appear if FileVault is enabled.
To get to the point in the login process where you can reset the password, click the question mark that appears on the right side of the password field or just try to log in three times. After the third failed login attempt, the Mac will prompt you with the password reminder, if one is set, and give you the option of resetting the password using your Apple ID.
Then enter the Apple ID email address and password and follow the onscreen instructions. Gimp mac download 10.5.8.
Reset the Password Using the Reset Password Assistant
If the “Allow user to reset password using Apple ID” option isn’t enabled, or the previous method doesn’t work, there’s still a way to use Apple ID credentials to reset the admin password. You’ll need to use Apple’s Reset Password assistant, which requires that you reboot into macOS Recovery and use Terminal:
- To enter macOS Recovery, restart the Mac. As it’s starting up, press and hold Command-R until you see the Apple logo, at which point you can let go.
- Once in macOS Recovery, ignore the main window and choose Utilities > Terminal, which opens a Terminal window.
- In that window, type
resetpassword
and press Return to open the Reset Password assistant.
Either way, once you’re in the Reset Password assistant, select “I Forgot My Password” and click Next.
If the account for which you wish to reset the password is a standard account, rather than an admin account, all you have to do is enter a new password.
For an admin account, you’ll instead have to enter the password for the account’s associated Apple ID. (If you don’t know it, you can click “Forgot Apple ID or password?” to move on to the Apple ID recovery process, which may require your trusted phone numbers.) Once you have entered the necessary password, you may be prompted for a two-factor authentication verification code, which will arrive on another device connected to that Apple ID. (If the Mac is your only Apple device, you should be able to receive the code from a phone call or SMS text message.) Finally, you’ll get to a screen where you can enter a new password and password hint.
What If You Use FileVault?
FileVault encrypts the Mac’s boot volume, making it readable only after the appropriate login credentials are entered, typically those of the primary admin account. The process for resetting the admin password changes a bit if FileVault is turned on because FileVault eliminates the option to reset the password with Apple ID credentials.
Fortunately, the method remains simple: enter a random password three times at the login screen, after which you’ll be prompted to reset the password using your Apple ID or recovery key.
Apple notes that you may still have trouble logging in with the new password after all this, and if so, suggests that you use the Reset Password assistant to reset the password again, using the “My password doesn’t work when logging in” option and following the subsequent instructions.
I hope your FileVault recovery key is stored in a safe place, like 1Password or LastPass! If it wasn’t saved or you can’t access it, you may want to turn off FileVault before you get into a situation where you can’t log into the Mac. In my experience, it’s easier to back up the drive, erase it, and then restore it, than it is to turn off FileVault.
Dealing with the Keychain
The keychain is an encrypted container associated with each user account that stores login credentials for apps, network servers, AirPort base stations, and Web sites accessed in Safari. It’s easy to forget about the keychain because it is typically protected by the same password used to log in to the account. As a result, resetting the password for an admin account means that you can no longer access the keychain for that account. Sorry, but there’s no way to recover that information.
After resetting the admin password and logging in again, you will likely receive an alert that macOS was unable to unlock your login keychain. Click Create New Keychain to start fresh. If you don’t receive the alert and have problems with the keychain, follow these steps to reset it:
- Open Keychain Access from
/Applications/Utilities
. - Choose Keychain Access > Preferences and click Reset My Default Keychains, which creates a new keychain with no password.
- Log out of the account by choosing Apple > Log Out Username.
- Log back into the account to tie the account password to the new keychain.

Don’t Reset Passwords Willy-Nilly
As you can see, there are a variety of ways that you can reset a lost or forgotten admin password and regain access to a Mac, although they all depend on knowing either another admin password or an Apple ID password.
However, don’t reset an admin password unless doing so is absolutely necessary because the login keychain will be lost in the process, and that will likely cause future annoyance.

If you’re not yet in this situation, take precautionary measures now! Be sure that your Macs’ passwords and any FileVault recovery keys are stored in secure locations that you—and other trusted users—can access easily. And of course, make sure to keep regular backups, which can help you recover from a multitude of sins.
