Old iMac os Help Needed
Ok First off just want to say i am new to mac's and i was able to pick this mac up from a school that was closing the only issue that i am having is the school did not clear the os back to factory nor did they give an os disc it is running os 8.6 but i am locked out of the main admin account!
I guess my question is, is there a way for me to reset the os without a disc (can not afford to buy an os at this time) or is there a way for me to install a new copy of the os via usb? If so how would i go about doing it i have been searching all over the internet and can't find any info on it so i came here to the hub of apple! ^.^
PS. Thanks for the future help in this matter.... ^.^
iMac, Mac OS 8.6 or Earlier
