Mac-tan
FANMac-tan is not one girl. Futaba used a generic Mac OS / Mac OS X personification as a rival to the Windows sisters — TV Tropes remembers bomb-throwing fights with 95-tan. +Nijiura+ decided that was inadequate and split the OS X codenames into Cheetah, Puma, Jaguar, Panther, Tiger, Leopard (and later cats). OSC's canon list follows the animal line for OS X 10.0–10.4.
Classic Mac OS 9 sometimes gets her own personification once the generic Mac girl is retconned into 'the OS X line.' If a gallery labels a catgirl 'Mac-tan' without a version, it is probably +Nijiura+ wallpaper culture, not 2003 Vault Mac.
Toy's iMac Girl is a precursor, not a Mac-tan. Apple's own later mascots are CORP-adjacent advertising, not this family.
