optisk digetal 3,5mm utgång.

Ja, det har du.

Enligt Everymac.com har den inte det. Optisk finns bara på MBP 15" när det gäller bärbara år 2011.

Då har Everymac.com fel. Optisk/3,5 mm kombo-kontakt för ljud ut finns i samtliga modeller av Macbook Pro.

Enligt Mactracker:

Introduced February 2011
Discontinued October 2011
