Despite thinking that old technology is better, she introduced some innovations. She is observant, witty, and intelligent; also more calm and stable than System 1-tan, but is uptight and does not tolerate getting ignored. Like System 4-tan, she has an inferiority complex, but usually does not handle it constructively, and is prone to verbal aggression when ignored for too long.
She gets along best with Apple II-tan, Macintosh System 1-tan, Macintosh System 4-tan, Mac OSX Panther-tan and Mac OSX Leopard-tan.
===Family and relationships===
Like most of the early Mac-tans, System 2-tan has also been retired or semi-retired for years, but maintained a supporting role. She gets along well with most of her family, but is frustrated over being frequently misunderstood or ignored when she gives advice, and is frustrated by family conflicts that emerge, and tries to avoid getting caught in them. She has an inferiority complex from feeling overshadowed by System 1-tan for being the first of the Classic Mac-tans, and System 3-tan for making more innovations she did. She did not immediately get along with System 3-tan since she was jealous over System 3-tan's achievements, and felt like her own were not enough during the short time she was the current Mac OS version.
This also reflects how Macintosh System 2 is one of the least used Mac OSes, was current for less than a year, and was supported only on the first two Macintosh models (the 128k and 512k) which could easily upgraded to System 3. These same two Macs also support System 1 which may actually be used less than System 2 but has a legacy for being the first, and the history behind it.
