If you connect an ethernet cable will the computer automatically connect to the internet? Says sometimes trying to reinstall os reset will work with the internet connection on the apple support.
what is ctrl is ctrl considered command? So its options-alt command-windows +r+p or command+r on startup but having trouble. I read somewhere that before 2010 imac had the pw stored in the ram and after 2010 they were stored in the efi.
So basically have to swap a ram the max capacity is 4gb of this model and it has two slots only comes with a 1gb ram 250gb hd from the factory. SO basically id have to get a new ram as its 2007 imac and attempt this again alt/windows/r/p which will chime flash 3 times and then reboot to a normal screen without a pw lock. After that i believe you can reinstall the original ram.
Somewhere i read you have to change the size of the ram to perform this task some have 4 slots and 2 rams already so youd only have to remove one and do this method but as its only a 2 slot 1gb ram from the factory and max capacity 4gb. They sell 2 2gb rams for this model for 10$ on amazon.May be worth the try.
Other then that does anyone know on an older 2007 os 10.4.10 imac 20" 1gb ram 250gb hd how to reset it with a admin pw lock thats forgotten. I talked with apple support we tried several methods trying to get to diagnostics and only got to the macintosh hd globe screen by holding alt.
Im trying to do the command+r on start up to erase all disc data macintosh hd then reinstall o/s.
