Hello.

Im trying to reset my iMac 27" back to factory standard, having recently moved office i have mis placed my operating disk which does this for me.

is there any way i can do it without having to use the disk? i attempted to use my smaller iMacs disk but it didn't work.

help please

have you backed it up using time machine? if you have then just go back to the earliest date of recovery
