I bought this mac mini in August 19', but haven't used it for a few months. Currently running Mojave, but I can upgrade it for you if you'd like. Its a base model "2018" mini. Apple recently updated these computers, but Apple only upgraded the base storage amount to 256GB. The other specs remain the same, so the older mini's are still fairly current. Specs: Intel i3 cpu, 8GB ram, 128Gb ssd. This mac comes with 2 years of remaining Applecare. No marks or scratches, or other issues. Selling because I no longer need/use it for school. Located in Duncan, text or email please :)
