Automatic safe boot - Password not reckognized

[gori1084]

Hi everyone,

I own a MacBook, bought in 2008 with Leopard as an OS. It is the balck model, if this helps.

While I was browsing, Firefox started behaving strangely. It was taking forever to minimize windows and could not use the top right function to view all applications/windows open. I restarted the mac but when it booted up again it did not do it properly. For 10 minutes I had the greyish screen with the loading sign underneath the apple logo, then eventually it showed me the safe boot mode, asking for my password. When I enetered it, it did not accept it (login window shaked at each attempt). I tried to log in from the CD, but again asked the password and did not accept the one I put in, even though I know it was the right one!

Now I can't use the mac and can't access safe boot either. Would you know any workaround solution for this, like a way to reset the password?
Have you got any clue on why the mac decided all in a sudden to boot up through the safe boot mode?

Thank you very much for your help!

If you have your install disc, boot from that.

Select your language and then look for a drop down menu in the menu bar for utilities. From here you should first run Disk Utility, verify/repair disk. Note if it finds and is able to repair any errors. If it cannot repair the errors, you'll need to take your machine in or use another, better, disk utility like DiskWarrior or DiskGenius to proceed.

In the same drop down menu as Disk Utility you'll see an option to reset password.
