Can't remember my Admin password on iMac 10.5.8
Hi everyone. I am running into a major issue. I cannot remember my iMac admin password (10.5.8) and I have tried everything that was suggested on this website along with multiple other sites.
When I startup my iMac it automatically logs onto my admin desktop (no password, etc.) I want to install something and I cannot make changes to my account because I can't remember my password. I have tried rebooting with command + S and whenever I enter in the commands, I either get error messages or am told the commands are not recognized. Any advice would be really appreciated. I do not have the original CDs. I am able to log onto a Standard and Guest account- just can't install anything because they're not the Admin account.
Driving myself crazy. Please help!
iMac (24-inch Early 2008), 10.5.8
