Mar 08, 2015 Do note the password change will apply to root regardless of how it was enabled, either through the command line or Directory Utility in OS X. Obvious to longtime users, the root user account login will always be ‘root’, it’s only the password that will change. Just boot up from the OS X Installer CD and go to Utilities Firmware Password Utility and set a firmware password. This prevents other folks from being able to boot up your computer from another. Just follow the Mac OS X password reset directions below to get a new account password. WARNING: Do not use the instructions in this document to reset the password for a FileVault protected account. Doing so may render the contents of the account inaccessible. May 03, 2020 Turn the virtual machine back on and it should boot into the Mac OS X first time set up menu. At some of the menus during setup it may take a while to progress to the next step, but be patient. Once the setup is complete you should boot into a fresh Mac OS X 10.5 Leopard desktop!

This is dangerous!
This is a standard feature of all unix implementations, as it should be. There is essentially no way of securing a
computer against someone with physical access to it; at the very most, you may introduce the inconvenience of
removing the hard drive from your machine and mounting it on some other computer which they already control.
Given that you cannot trust any computer, running any existing operating system, to be safe against an attacker
with physical access, this really is a feature, and not a bug.

I guess I just need to start thinking that way (that it's normal). My first thought was 'geez,
someone could steal all my data files.' Well, of course they can do that under 9.0 as well,
and I never worried about it there!
I was also considering how will I get back into the machine if this were to happen .. guess
that's simple; just repeat the process!
It is indeed a brave new world for the longtime Mac OS crowd - and it's quite interesting!

No, it is not. I know SCO OpenServer5, which is a Unix system that can be installed according to different safety standards (with C2 = 'military grad' as the highest safety level). Even on the lowest (traditional Unix) safety level, it is not possible to boot SCO5 in single user mode and get to a shell without entering the root password. AFAIK, Linux and other Unix systems behave this way. If not, breaching system security (worse) undetected (much worser!!!) would be very, very easy. While it is always possible to break system security when you have physical access to a server, on SCO5 you have to remove the disk array and mount it on a different system. In this case, a security breach can be at least detected (missing drives; broken drive hatches, if locked; .).* If booting into single user mode gives you some or all root privileges without root password, an attacker would simply install a backdoor mechanism to the system, which might be very difficult to detect. No need to change the root password or remove disks. IMHO if you 'lose' the root password and there is a way to get it 'back' (reseting or changing it) without having to reinstall the system from ground up, the system is not trustworthy in terms of security. Just my $0.02 *) You can prevent that stolen disks are 'useful' for thieves, if you encrypt the filesystem (don't know, if this is possible on OS X).
i am running 10.3.4 and i did not do the initial installation on this machine. I have an account with admin rights. but as far as root i dont know the password. when i try the above steps it a doesnt go to localhost% is goes to root# when i enter the commands as stated it mounts the drive successfully and it also initializes through the SystemStartup then on the passwd root it just drops the carrier down and provides no information to enter the new password or any errors. just allow to type continuously until hitting ctrl-c at which you return to the prompt. please help
I have just received the final release and all you will need to change root password is to reboot your Mac with the Installer CD.
Before you install, go to the menu and you will see an option to reset all user + root passwords.
Would not like a CD to get into the wrong hands!
Cheers

I havent seen this here, but it is easier just to type this in the terminal:
At prompt enter admin (your) password
Now, fix your root password.
Now you're all set!
At prompt enter admin (your) password
Now, fix your root password.
Now you're all set!
if you've forgotten every single password, then you're SOL using your method.
the one in the tip is for desperation, last-ditch efforts.

There are _two_ commands at boot time -- one is to check the filesystem,
I think it's fsck -y
THEN you do mount -uw /
(regardless, you'll get prompted to do both of these things when you boot into single user mode.)
instead of SystemStarter I'd suggest only running NetInfo, since that's where the password is getting stored..
cd /var/db/netinfo
netinfod -s local
passwd username
<type the password in>
exit
the system now boots into normal multi user mode.
I'd just say that it'd take a lot longer and be kind of silly to start a whole bunch of services when all you need is access to netinfo. ;)

For those bothered by this who would like to be able to prevent someone from doing this, you may want to use the Open Firmware password application. The page on Apple's support site to download it is found here. Installing this prevents starting up in single user mode, resetting the PRAM, and other things insanely useful when stuff goes wrong. Be careful, though, because if you forget this password, you're screwed.
Yes you are screwed if you forget the Open Firmware Password, however, a quick trip to your Apple Authorized Service Provider can fix it for a small fee and lecture!
You can save yourself a trip to an Authorized Apple service center if you change the physical configuration of the machine (i.e. remove/add RAM). This forces a reset of any password applied to the Open Firmware. This is what the linked KB article says.
Does this apply to any other OS, like, OS 9, Panther???
In Panther you have to run the netinfo one. Mac 10.1, and 10.2 you are able to use single user mode with mount -uw and system starter. However, you will need to run the netinfo one for Panther. Panther loads Apache Web server when you do normal startup. Therefore, when it goes to open it, it is available. In single user mode, you must run systemstarter to load the users into the OS. But, in SU mode, Apache hasn't been loaded so it will keep waiting for it and you will not have access to the passwd command.
Interesting info. 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. Once in single user mode with the filesystem mounted and writeable.. # visudo
Add an entry like this:
someuser ALL=(ALL)NOPASSWD: ALL
Reboot, fire up a terminal, and..
$ sudo -s
# passwd
Now you've changed the root password, and you can do whatever you need. Remember to use visudo to remove that entry from /etc/sudoers, because it is dangerous!
This is the solution I found it has no limitations but you need to have a windows PC and any macDisk software:
MacDisk is a software that allows to look into any Mac HardDisk and read/modify/delete its content without any need for any passoword.
Once you installed on the Windows PC your MAC Hard Disk (make sure Windows do not write any signatures on it by cancelling its request)
go on the preferencies folder (this work for both OS 9 and OS x) and then in the System Folder locate the file named Multi-User Prefs and delete it. Then do a normal restart.
Note thas this procedure will also allow the recovery of your files from the PC
Enjoy it

Create a new login keychain, if necessary
After resetting your password and logging back in to your account, you might see an alert that the system was unable to unlock your login keychain. This is expected, because the passwords for your user account and login keychain no longer match. Just click the Create New Keychain button in the alert.
If you didn't see an alert about your login keychain, or you see other messages asking for your old password, reset your keychain manually:
- Open Keychain Access, which is in the Utilities folder of your Applications folder.
- Choose Preferences from the Keychain Access menu, then click the Reset My Default Keychain button in the preferences window. After you enter your new password, Keychain Access creates an empty login keychain with no password. Click OK to confirm.
If you don't see a Reset My Default keychain button, close the preferences window and select the “login” keychain from the left side of the Keychain Access window. Press the Delete key, then click Delete References. - Choose Log Out from the Apple menu to return to the login screen.
- Log in to your account using your new password. Your account password and login keychain password now match again.
If you still can't log in
If you still can't log in with your password, contact Apple Support for help.
