Hey everyone ! I purchased a imac 2006 from a friend cause he no longer needed it. Well when i got it I was on it for sometime and I was deleting and adding my stuff and info.. as soon as I turn the computer off , everything went back to its normal settings and everything I added got deleted. So untried testing it out and downloading a program into it. then restarted the computer and it did the samething. Please if anyone knows what the problem is please feel free to email me or comment back. Stevenrodriguez57@gmail.com ...I also tried command codes to reboot it like a new comp , and inserted the dcs to install mac and nothing. It's still the same. Please help!!
