What version of Thunderbolt is on my MacBook Pro A1398
My A1398 MacBook Pro with serial C02PX4DKG8WP is not working with a new Thunderbolt external drive that uses a USB-C connector. My MacBook has the older Thunderbolt/Thunderbolt 2 style connector, so I bought a Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter from Apple (MMEL2AM/A). I also bought a Thunderbolt cable from Apple (MD862LL/A). When I connect these together and plug them into the new drive nothing happens. The drive does power up when I plug it into a newer Thunderbolt 3 compatible computer, so the drive seems fine. Is this combination of cable and adapter just not going to work with the newer drive? Thanks.
