  • Yes, at least for the later manufacturing runs. I have it running in full 5K on my "27-inch, Late 2015" iMac. However, may be worth caveating that my iMac was manufactured in April of 2017, one of the last of old model, so it is possible that some changes were made during the production life. While the description for the shown in my system "About" screen is "iMac (Retina 5K, 27-inch, Late 2015)", the model number shown in the "System Report..." screen is "iMac17,1".

  • No. These 5K displays require a 15" MacBook Pro /w TouchBar Late 2016 or later computer.
