This could not have been refurbished or tested, due to its odd disk partitions shown in image. Box also arrived wrapped in very heavy ducktape, oddly wrapped like a young child packaged it, prompting me to ask UPS driver to wait so I could open box to confirm an iMac was inside. The 1T storage doesn’t work showing too full to even do a small update on OS. It is also missing the Apple keyboard & mouse, and came with an extremely cheap generic keyboard and mouse in its place
