Password not recognized.
Hello,
After I tried to up graded my iMac 24" 2008 to El Capitan, from Mavericks, this one stop it upgrade at the end of it asking to restart, but no any restart are able to install it... I tried to go back to Mavericks, but no Hard Disk to restart it, so I re-started it with my CD Snow Leopard, it was ok for different choices, then with Time Capsule and a backup of it, I was able to restore the OS, but now my iMac is asking for my password, I know it and the ancient too, but no success to open my session...
Have you an idea to operate?
Thank you for your help.
