I have the same question.
Can I use the iMac 21.5 inch late 2012 to connect an external drive HDD through the port thunderbolt. I used the following equipment:
- Cable thunderbolt Apple A1410
- Adapter Apple MMEL2AM/A
- 2.5-inch hard drive enclosure with USB -C port.
Nothing succeeded.
Everything works
through USB-3.
What am I doing wrong? How do I use Thunderbolt 1?

You need a Thunderbolt drive, it can be confusing...
Details:This model is equipped with two Thunderbolt ports. Thunderbolt is backwards-compatible with Mini DisplayPort-equipped displays as well as adapters that are compatible with Mini DisplayPort (DVI, VGA, dual-link DVI and HDMI). It also can support other peripherals that use the Thunderbolt standard, which provides a maximum theoretical 10 Gbps of bandwidth in both directions.
Macs with USB-C/Thunderbolt 3 ports. These ports support DisplayPort, Thunderbolt (up to 40 Gbps), and USB 3.1 Generation 2 (up to 10 Gbps). Adapters also are available to use Thunderbolt 2, HDMI, DVI, and VGA.
