I bought the MacBook Pro in 2013 and used it until I got an 'Air. My wife used it for awhile and I upgraded it with a 240GB SSD and another 4GB memory for a total of 8GB. The system is pretty snappy considering it's age.  The installed OS is Catalina 10.15.x. The power supply is not original but a well working clone.  This'll be great for any mainstream application.
