The product is not directly compatible with your iMac (Retina 5K, 27", Late 2015) as it is an enclosure for M.2 SSDs and connects via USB-A, while your iMac uses proprietary PCIe connectors. You may need an adapter or other solution to use it.

The enclosure is only compatible with original Apple SSDs, not with OWC SSDs, including the OWC Aura Pro X2. It works with the Macbook Pro Retina Mid 2015.

According to the manufacturer, this product is compatible with your Macbook Air.

No: this SSD is compatible with the MB Retina mid 2012 and early 2013. So 10.1 and 10.2. These are the first MacBookPro Retina 15" and 13" between June 2012 to Sept 2013.

However, this is article OWCSSDA12K960, so the subtitle is correct. Only the text in Information is not correct.
