Hate to be a nube but how can I tell if my Mac Mini (late 2012) is a hdd or ssd? I want to beef it up with upgrades. Currently: 2.5 GHz Intel Core i5; 4 GB 1600 MHz DDR3; Intel HD Graphics 4000 1024 MB; OS X 10.9.5 (13F1911).
Also not showing any available software updates... what's up with that?
Any help or guidance appreciated.
