Worked for me on the 2001 iMac and it came up as OS X 10.1 after I was able to get in

Localhost recommended I run these two lines first
/sbin/fsck -y
and
/sbin/mount -uw /
(root was read only) so I did that before doing the remove.

It left everything on the hard drive, not that I want it.

> is it that simple to hack into a mac…

yes, it is - but only if the mac is not specifically
protected.

This is not a security leak. It is by design and
intentional, since most personal computers are
what the thing is called i.e. a personal item.

Booting into single user mode is a thing as old as
Unix. I used the trick on Unix V7 - early 80ies.

Most systems boot automatically using a standard
boot command line invisible to the user. And most
Unix including Mac OS X allow you to get into a
manual mode and specify your own parameters e.g. -s
to go to single user mode. In single user mode you are
omnipotent root, can mount disks and change every bit
on your system disk i.e. add new users, delete users
etc…

The trick fooling the system into an automatic
initial setup script is one way. There are more
traditional ways to reset password, like
editing /etc/passwd in very old systems or
nicl /var/db/netinfo/local.nidb… 10.5. needs
an even newer trick which I don’t know/use yet.
But such one will exist by design.

—

If you want to prevent this you can get a utility
(google for “firmware password”) and set a firmware
password for the machine. You will set a variable in
NVRAM of the machine and this prevents any key
combinations from changing the boot parameters.

The user of the machine is forced into a
regular OS boot on the default drive and you
loose the chance chance to intercept and
walk into the machine through the boot door.
That way you will end with the login prompt
and be locked out if you are not a regularly
authorized user.

But again - if you have physical control over
the machine you can remove the firmware password
(by changing the memory configuration on most macs
i.e. remove or add memory).

Discouraging the manipulation of an operating
system image always boils down to a padlock on
the machine on the lowest hardware layer. The best
experts on this are probably system administrators
in schools and colleges around the world - because
they have to (had to) provide personal computers
to their students in a public place. At least that
is where I gained this expertise.

this does work. i just did it on a MBP running 10.5.5.

after doing it, i kind of panicked and thought i had just deleted all of my data, but rest assured that this process does not.

it will take you through your initial setup again, but all it does is create another account. your original account will remain.

i would think that passwd [username] would have worked fine. i will retry that. it may save from having to go through the entire setup again.

Mikey Said:
“Yep you guessed it. I’m a PC.”

And always, have been, that was obvious by line 4 of your post
Even back then the Mac was all but immune from Trojans and Virus and clicking that link would have done nothing

I can’t believe anyone would actually go to a HACKING APPLE BLOG and then take the commands that the poster put on there and actually type them into the prompt. I learned that lesson back in an old AOL chatroom. I curiously asked the user where he got that cool ass rainbow font. He simply posted the link and “I” installed the backdoor trojan horse not knowing that It was exactly what he wanted me to do. Most peolple don’t remember the web when it was dangerous. God how I miss the sound of AOL 4.0 logging on to my dial-up modem. No disrespect to the poster. I see the point in having a blog like this but I just don’t think people see the danger in taking advice from a blog. If this guy said reformat your hard disk but he told you how to do it in code from a prompt so you didn’t know what you were doing you would probably do it blindly. I’m not saying that the code is incorrect that he posted. ( I ignorantly didn’t check into that.) Sorry poster. You sound like you know what your talking about so I hope you can understand I’m not attacking your blog. For all I know It’s good commands but I trust you as much as the rainbow font guy. That’s how everyone should trust what they read on a blog. I hope this works because I’m gonna try it either way because it’s not my laptop and I don’t care if it ruins my friends MAC. Yep you guessed it. I’m a PC.

Be sure to type it exactly (including spaces and caps). Do each line one at a time, hitting Enter after each. I did this on 10.3 and 10.5.

mount -uw /

rm /var/db/.AppleSetupDone

shutdown -h now

Pls i have tried all i could but i still dont get any of this. I need someone to help me out you can get me on my mail. authenticnelly@yahoo.com
Its a version 10.4.10. Kindly help me with procedures on how to reset the password.
Thanks

Patrick Lewis — Tue, 14 Oct 2008 03:03:45 +0000

Thanks. This works BEAUTIFULLY. I am selling some old macs and used this to “Virginize” them. I did it twice on each machine. First to create a user named DeleteThis User. I used this new user to delete the original (my) user. And then did the reset again.

Thanks a ton.

Would this method also set the new admin as the owner. I mean to have a used computer transferred to a new owner (name, address, etc.).

I was able to get it to work, but only after pulling out the RAM and restarting the machine. It was the only way to get past the lock which prevented any of the hot key combo’s during start up. Once the RAM was out I had no problems using “Apple S” - that method should probably be included in this procedure for those encountering the same problem I did. Cheers!

This method seems to work fine. To all those who tell you to use passwd - it doesn’t work in 10.3.x and above…

I’ve just tried this method several dozen times on an old Apple ibook 500 running 10.4.8 and it doesn’t work.

The install CD method doesn’t work either as they are the original 10.2, nor does the restore CD method.

So I tried this method using “Apple S” holding it down before, during, and after the chime, but no luck. Tried various intensities on the keys, no luck either.

Any ideas?

Do as he says but upon the start up you will here a chime THE APPLE CHIME :)! Once that is done, you have a 3 second time period to hit Apple Command - s. This works on any COMPUTER using Mac OS X 10.4.0 - 11. You must hold both firmly not to tough to brake your keys just enough to let it know whose boss. A screen “WILL!!!!” Pop up and you must hold both of them down at the same time until that appears. Once it does you will wait about a minute then do as it says and Voila! It works and FOR ALL THE NAY SAYERS NO it doesn’t wipe your information say do not transfer anything, and nothing is wiped. Logon as the admin and put in your password and change the old admins privileges to standard and then change yours to admin settings then reset the password on the old one to something you will remember. Then log out and go onto the old one and ALL OF YOUR THINGS ARE THERE AND NOTHING IS DELETED I HAVE DONE THIS 20000 TIMES TRUST ME my company uses macs and so many people forget the password and it takes to much time to do this with the disk that its easier this way and nothing will be deleted if you just put in the information needed nothing more don’t transfer anything.

Example -
The old account let say was name. JoeShomo!
Joeshomo forgot his password and doesn’t no how to get it back
Reads this then says okay. Shuts down his computer, turns it on hears the chime 3 notes before the end hits Apple Command - S together comes to the text screen.
Types in what it says and then reboots.
Comes to the First time start up screen. Follows the instructions and doesn’t transfer anything “TRUST ME DONT TRANSFER!!!”
Then names his new account FIXER!!!
He Logs on to FIXER!!! and goes to Account Preference.
Clicks make this computer an administrator! ” No need to put in any password here ”
Clicks on the Lock if its locked which it will be if someone is secure with there computer.
Goes to the JoeShomo account and clicks don’t allow administrator privileges.
Then below the names and Short name, clicks reset password!!
Change it to what ever you want that you will remember and finish up.
Close the Account settings.
Log out and go to the JoeShomo account don’t be worried your stuff is there!!
And if your smart you will leave FIXER!!! account or whatever you name it!
But if not then change it back and that does it.
DON”T LISTEN TO PEOPLE THAT TELL YOU THAT IT WILL SCREW ANYTHING UP IT WONT ITS JUST A glitch that allows the computer to think its the first time starting up but doesn’t wipe the hard drive. Because it already has a OS. Just a refresher if you will.

If that doesn’t help and you need more then that contact me at
dyllenowens@ymail.com I will help you further!!!
Any other problems contact ME WILLING TO HELP

However, upon entering the OS screen, where its loading…it has a small folder icon, and flashing to Mac face Icon….Wont do anything, acts as if everything is wiped…which means I would need a CD.

EW says:
You fail to mention that in the process you delete ALL of your information.

That is not resetting the OS X password, that is called creating a new account and taking over someone else’s computer with a fresh start. The title of this post should be changed.

MY REPLY: by the way i did that to my mac and i got all the data back. The hard drive didn’t
delete it

Hi,

I tried this on my personal MacBook, which runs the latest version of Leopard and it worked exactly as advertised.

I REALLY want to do this with my MacBook Pro from work, which runs Tiger 10.4.10. Can anyone confirm that this also works with Tiger?? I’m a little concerned about trying it on my work machine. I can’t make a true backup without Admin rights…

If anyone knows if this works in Tiger, please let me know.

Thank you!

@ devious: When booted into OS X, change your startup disk to the Mac HD in System Prefs > Startup Disk. When you reboot, it will boot into OS X by default (instead of Windows), and then you can boot into Single User mode.

Oh, and using punctuation is not a bad habit to get into.
