I have an older imac that asks me for a password on startup. Is there anyway I can change this password?

If you have the MacOS CD that came with your iMac, you can boot from that CD, then go through the beginning of the setup process until you get to the point where you can use the password reset tool.

first you need a boot disk. if they did not leave you with one try calling apple and asking for a replacement one (or call to change the password but thats a lot more work)

(800 SOS-APPL)

if u couldnt change the password by calling them for help

Once you have an install disk in hand turn off computer put in disk turn on and it should load if it doesnt just call apple again (800 SOS-APPL)

well call the person you got the computer from and ask them to give you the password if that don't help have someone to hatch into the computer or just get a new computer.

in case you nonetheless have the education manuals for that computing gadget then you may "flash the bios " i.e. reset the bios settings by technique of shifting a jumper on the motherboard for 5 seconds and then putting the jumper back to its unique position.this may reset the computing gadget to its starting up with out passwords by any skill.

take the computer to a tecknician let him clean out the computer and reload it and then you can set your own password......

Yes. look in the bios for your anser
