1. Find the old password,
2. Use the Keychain utility and create a new Keychain.
doing the second will eliminate your keychain and all passwords, etc.
This is why you should always have a record of passwords. The Admin user or root can change a user password.
My daughter has a MacBook with OS X 10.4.11. Due to its age & configuration, the OS X can't be updated any further.
Her MacBook is networked through my iMac (OS X 10.6.4) and is setup to print via my printer.
The connection to the printer stopped working, I tried to troubleshoot it, but needed the admin password. She didn't know if she had one so I used the installation disk to change eliminate the need for one. But for some things I'm asked for the keychain password, she doesn't remember if she has one.
According to the keychain help, the keychain password should automatically be the same as the admin or login password. There isn't a login password anymore, and keychain isn't accepting a blank password,so I'm locked out of some functions requiring the keychain.
I created a new keychain, but when online, I get a lot of unverified certificate errors. I try to change them individually to accept them, but I'm asked for the keychain password. If I can access the old keychain, is there a way to copy all of its certificates to the new keychain?
I can't figure out how to change the keychain password for the old keychain as without it, I can't accept certificates even with the new keychain. I'm really stuck. Any suggestions?
