Late 2009 27” iMac in very good condition. It is running High Sierra OS with 1TB storage, 4GB memory and a 3.06GHz Intel core 2 processor. I just installed High Sierra and is setup for a new owner. It would be a great beginners Apple computer for someone just learning. The large 27” screen is really nice. A mouse and keyboard is not included. If you have any questions let me know. Thanks for looking.
