NewerTech has released a new adapter that allows a 2012 or newer model iMac (including the latest Retina 5K iMac) to be hung with a universal VESA mounting system. Since 2012, Apple has made it so that iMacs must be ordered with a VESA mount at the time of ordering, which means four screw holes would be drilled into the back -- if the original purchaser did not order the custom VESA fitting, there was no option to remove the stand, or add the option to mount it later.
