Definitely a nine out of 10. I have used this thing from the beginning and unfortunately had to upgrade to another machine because of work. It works flawlessly… Now for the AI description… This Apple iMac Late 2013 comes with a powerful Intel Core i7 4th Gen. processor that runs at 3.10 GHz. It also has a 21.5 inch screen size and 16GB of RAM that makes it perfect for a variety of uses such as office work, demanding programs, industrial engineering coding, casual computing, and graphic design. In addition, this desktop has a NVIDIA GeForce GT 750M graphics processing unit, USB 1.0/1.1, Thunderbolt, and USB 2.0 connectivity, and it runs on Mac OS 10.15, Catalina.
