This is a very good condition, 2012 27inch iMac with i7 3.4GHz CPU, 16GBs of RAM and a 500GB SSD with Mac OS Sonoma installed using the excellent Open Core Legay Patcher. The iMac overall is in great condition with just one bug, literally, there is a very small insect squished under the glass of the display (see photo).
Due to the way these screens are manufactured I think it must have happened in the factory when the display was being assembled and so I can't see any way to remove it.
Genuine Apple wireless keyboard and mouse are included
