Hi All, I agreed to sell my iMac, and tried to reset it. I used the keys Command + R and erased the disk. When I tried to re-install the OS and after putting in the Apple ID and password, I get the message "this item is temporarily unavailable" I have been researching online and some of the solutions seem to be the following: 1. Use the original Apple ID - Which I did. 2. Make a bootable USB and use it to boot the iMac - I cannot as I do not have access to the OS anymore. I am sooo frustrated. I was hoping I could somehow make a bootable usb using my windows laptop.
