Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.
Unfortunately your computer is not compatible as it only has Thunderbolt 2 and USB-A. Our dock requires USB-C or Thunderbolt 3. It would be best to return the dock for a refund. If you need, I can provide you with a prepaid return shipping label, just contact me directly at firstname.lastname@example.org
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
