Hey guys, I bought a new iMac at Best Buy last night and everything was, is working fine. Until tonight. I came home, and tried to wake the computer up from sleep and couldn't do it. The mouse and keyboard would not connect. I connect my keyboard and mouse from my Dell, and went underway. I tired everything that I saw online. Could it be a hardware issue? I'd hate to go back and exchange it. I love it. But it's not even two days old. Any options for me? Reinstall Mountain Lion?
