Seller sent me a very old model and lied that it was 2017. This is what was displayed on  Amazon about the products: “The stunning all-in-one iMac features a beautiful 27-inch Retina 5K widescreen display, quad-core Intel Core i5 processors and AMD Radeon R9 M390 graphics processor with 2GB of GDDR5 memory. And it comes standard with 8GB memory, a 1TB fusion drive, and advanced, high-speed I/O, including two Thunderbolt ports and four USB 3 ports.Per the Amazon page this was 1st issued in 2016. Now it is basically a 9 year old (2013) brick that can not be updated. Also says GDDR5, it is not, it is DDR3.
