Unfortunately, this SSD only fits with the Macbook Pro Retina 13" late 2012 and early 2013.

No, unfortunately not. You need the "OWC Aura" (without 6G in the product title) for the MacBook Pro Retina 13" (Late 2013). Unfortunately, this product is not available at Digitec. Item number: OWCSSDAB2MB05K
