I agree with Dan that you may be better off saving your pennies for a newer system. That version is considered obsolete so software and OS updates may look up to date but they just aren't being updated by Apple anymore. If a new Mac purchase is too expensive you may want to check the Apple web site for their refurbished models. They are thoroughly rebuilt and tested and less expensive than new. Today I see an offer for a refurbished 12-in MacBook 1.1 GHz Dual-Core Intel from 2016 in gold or silver for $949.
