El primer que van treure va ser un Mac Os 6, un sistema operatiu molt senzill.<br />A més d’identificar el sistema operatiu amb un número, se li afegeixen les actualitzacions. Per exemple, en el 6.1, l’1 es per identificar el número d’actualització que és.<br /><br />Mac Os X<br /><br />A partir del Mac Os 9 van pasar al Mac Os X. És la última versió de la serie Macintosh. Inclou una interfaç gràfica creada per Apple, anomenada Aqua. Incorpora un sistema operatiu anomenat Unix.<br />UNIX: Són sistemes complicats, no es pengen i són de teclat. És “multitarea”, és a dir, permet executar diferents procesos alhora. Aquest sistema el van fer amb una gràfica on es pot ultilitzar el ratolí juntament amb el teclat. Per dintre és Unix però, per fora, és una capa Aqua.</span></p><p style="text-align: justify;font-family:trebuchet ms;"><span style="font-size:100%;"><br /><strong>Arquitectura del sistema operatiu:</strong><br /><br />Conté 4 capes:<br /><strong></strong></span></p><p style="text-align: justify;font-family:trebuchet ms;"><span style="font-size:100%;"><strong>1.</strong>Nucli Darwin: cor del sistema.

La memòria la gestiona el sistema i la reparteix entre les aplicacions segons la demanda, així quan es penja un programa, no penja tot l’ordinador.<br /></span></p><p style="text-align: justify;font-family:trebuchet ms;"><span style="font-size:100%;">-Multitarea real: permet utilitzar diferentes aplicacions al mateix temps.<br /></span></p><p style="text-align: justify;font-family:trebuchet ms;"><span style="font-size:100%;">-Open source: còdig obert.
