10.4: Reset password under 10.4 using 10.3 install disc System
Tiger only hintHere's the problem I had, and how I solved it. First, I swapped my standard Apple DVD drive for brand new DVD dual-layer burner. Then I changed my password whilst under the influence (don't do that -- it'll end in tears). I forgot the password after I sobered up, and at the same time, found that the new drive wouldn't read the Tiger install DVD.

So I booted using the Panther install CD, which seemed to work just fine. I selected the Reset Password option. It found my users (root and main), and allowed me to reset their passwords. Apart from some Keychain issues (which I am fixing now), I am once again able to install software, update the system, etc. So, it seems that a Panther disk will allow you to change passwords for users with a Tiger update. Hope this saves someone from having to go through the same 'tearing hair out' process that I have. Remember, back up your data before trying something like this. In my case, Tiger was installed over Panther, and I'm unable to test on a clean Tiger install.

[robg adds: Please don't comment that this is a security hole ... the Reset Password function is right there on the install discs, ready to be used on any machine. If someone has their hands on a Tiger install disc, they could just as easily have a Panther install disc. This hint will simply help someone who has a non-functional Tiger CD and a forgotten password.]

10.4: Reset password under 10.4 using 10.3 install disc

Minor nit: Tiger "CDs" aren't the normal way of installing Tiger. Most people who purchase Tiger will find their O/S on a DVD--and have to get CDs from Apple when they find their machines don't have DVD readers.

With regard to replacing the CD drive with a more powerful one, I used a different tack.

Instead of actually replacing the drive that came with my system (Mac Mini with DVD Reader/CD Writer), I purchased a 5.25" external drive enclosure from the local PC hardware shop. Most of these come with either USB 2.0 or Firewire interfaces (some have both). Installing the "internal" DVD burner is easy with these, and when you plug it into your Mac, everything just works.

The benefit of using an external drive is that I can move it from my Mac Mini to my iBook and even over to my Linux box when I have the need to burn a DVD on one of those systems. Thus, if the Tiger Install DVD has a problem dealing with my DVD burner, I can still use the DVD reader that came with my system.

Oh, important safety tip: DO NOT OPERATE YOUR COMPUTER UNDER THE INFLUENCE! This should be patently obvious to everybody, but I'm still amazed at the number of nasty emails, blog postings, and instant messages sent that are inspired by liquor or other mind altering substances. That clever line you wrote last night will come back to haunt you when your boss receives it the next day...! Be glad you only reset your password and didn't burn any bridges this time!

Hope this helps.

Thinking about it, maybe one should not make telephone calls whilst under the influence or even better talk at all. Better still, do not leave the house, or best just stay in bed. Or do not start drinking in the first place.

Seriously, it is much more fun to use the computer while drunk than while being sober...

foreign substances create great quotes though

I just wanted to add a second opinion to my colleagues keen observation about foreign substances and computer use. I am sorry for your frustrating experience, but the only tears here are from laughter. That is a damn funny quote!!! Glad your patient made it off the table Dr.

you can use pretty much any OSX installer cd to do this. I've used all sorts of different version install cds/netboot to reset passwords.

good thing apple hasnt really changed the netinfo database to the point where this no longer works

How were you able to get the Reset Password utility onto a netboot image? I've been trying this for a week now with no luck.

We have a netboot image that has all sorts of repair utilities and re-image utilities. I'd love to get the Reset Password utility on there. But of course it keeps saying it needs to be run from the installer disc. Grrrrrrr.

Regarding password reset using an install disk:

1. Physical access to the machine is required.
2. Physical access trumps other security mechanisms.
3. Therefore, use of the install CD or DVD is NOT A SECURITY RISK.
4. The real risk is in unsecured physical access to the system.
5. This applies REGARDLESS of the operating system in question.
6. This is most certainly true.

2. Physical access trumps other security mechanisms.
How very true, even an open firmware password can be easily reset with a little monking with the RAM and clearning the nvram. And there's always the good 'ol method of just putting the hard drive in another computer and grabbing all you need that way.

About the only measure I know of that stays true to security even with physical access is file vault. Correct me if I'm wrong, but afaik the user password is the only way to decrypt it, or will transferring it to another computer and setting a master password allow access to it?

Single-User Mode
Authored by: raggamuffin on Aug 29, '05 09:12:37AM

Pardon me if I'm wildly mistaken, but isn't it possible to just reboot into single-user mode (cmd+s) and change the password with 'passwd [user]', or does single-user mode block access to the NetInfo/user profile database?
