MacBook Pro – Change Account Password

I have a MacBook Pro 1,1 Intel Core Duo 1.83MHz and I’ve completely forgotten my account password. I have also misplaced the recovery CD’s. In the end I downloaded Tiger OS and I don’t know whether it’s because the Laptop isn’t compatible with that CD but it won’t boot from it…

Is there away of dropping down to the UNIX command prompt and changing the password from there? I really don’t want to have to order replacement recovery CD’s from Apple.

Your help will be much appreciated, Thanks

Hi,

I would strongly suggest you get the recovery CD/DVD to do it... If however, you really want to try:

1) Single user mode password reset.  I am not sure this will work with OS X 10.4: http://www.macosxhints.com/article.php?story=20001217230925152 
2) Force your machine to rebuild netinfo database: http://www.macosxhints.com/article.php?story=20010422111248923

There is no legal download of any Mac OS. The downloads from Apple are updates only.
So chances are good that what you downloaded is older than the revision of Mac OS 10.4 that is required to boot your laptop.
Your first stop should be:
www.apple.com/support

You can call to get replacement CDs. You will need them, or you'll need to purchase a reatail Universal Binary version of 10.4.7 or higher.

Failing that, here's the info from the source (Apple) about replacing your NetInfo database:
http://docs.info.apple.com/article.html?artnum=107210

The macosxhints article is the "quick and dirty" version.

Good luck.

It works out that the model of my MacBook Pro isn't supported/integrated in the latest release of a retail version Tiger OS X 10.4.6. Therefore I had to purchase new recovery discs as there seemed to be no other way round this.

The latest retail version of OS X 10.4 is the Universal Binary 10.4.7 , which supports both Intel and PPC (G5, G4, G3) processors.
