2019 Apple iMac 4K Intel i3 3.6GHz

As far as the physical condition, the iMac was very good. It was rated "excellent" but there are marks and dents (mostly on the rear and not visible) that, in my mind, do not merit an "excellent" rating. As far as performance, however - while I did not expect a 5-year old computer with an 8th generation i3 intel chip to be a speed demon, I did expect that I could surf the internet and check email. This machine is so slow, that I can only assume it's defective. My 2017 MacBook - which is 2 years older, has a broken screen, a ridiculously small HD, and a dead battery - runs circles around this thing. After a 10-minute boot time, I find that I cannot even load a webpage. Simply trying to open Safari is an act of utter aggravation. And you can forget about doing anything beyond that. You thought you were going to load an app? Forget about it. Microsoft Office? Ha! Load a PDF? You must be joking. For fun, or because I'm a masochist, I thought I'd try to upgrade it to Sonoma. If a computer can simply die of a broken spirit, then that's what this machine did. Do yourself a favor and save your $400 for a better system.
