27" Mid-2011 iMac Getting ready to sell it and upgrade to a newer model so I went to wipe it clean and when I'm trying to reinstall the OS from the recovery partition, it says it needs to contact apple to verify something, so I click OK and then it just stays on the next pop up which says "Loading Installation Information" I have 3 partitions Mackintosh, Recovery and Bootcamp (Windows 7). I completely erased the Mackintosh partition as all the online guides said todo. Nothing changed. When it's stuck on there, the mouse shows the color wheel so I can't click ANYTHING. You might suggest leaving it sit like that overnight- well it decides to put itself to sleep mode after 15 minutes (maybe 10). What can I do? I have a buyer lined up and this is holding me up and making me look pretty bad. Thanks in advance for any help.
