First released along with the Macintosh SE and the Macintosh II series is Macintosh System 4.
System 4-tan is represented having a 4-theme to her appearance, having 4 pigtails and 4 cowlicks, wearing a green minidress with a 4 printed on it, wearing a grey denim jacket with 4 buttons on it, having glasses (the expression 4 eyes comes to mind) and having a height of 4'4 [132 cm]. She is friendly, cheerful and carefree although rather picky as System 4 was the first Mac OS to exclude a model (does not support the original Macintosh/Mac 128k, 4.1 also dropped support on the 512k). However, despite her cheerfulness, she hides feelings of envy as well as an inferiority complex because she cannot multitask like her younger sisters and is less well-known than most of her sisters and that System 4.0-4.1 did not introduce any major features (besides supporting disk drives of 32+ MB) and is rarely considered. But despite that, she is usually able to keep a positive attitude and happily interact with her sisters.
