This Apple iMac is exactly as describe in the details on the post for this item. It is a 2019 iMac with 8GB of RAM with a 27” Retina 5K screen. However, I received my iMac with some scuff marks on the bottom of the stand and also on the bottom portion of the monitor. The screen so far is working in excellent condition. I had no problem setting up and upgrading the OS on my iMac and I didn’t have to call for any tech support for assistance so I can not really rate that service.
