In case you’re ever needing to connect a Dell Latitude 7480 laptop to a discontinued Apple Thunderbolt Display, rest assured it’s possible. The Dell has a Thunderbolt 3 port, whilst the Apple Thunderbolt Display has a Thunderbolt 2 cable. The solution is to buy a $49 adapter. I picked one up today at Best Buy and my Thunderbolt Display works as expected, just as if you were connecting it to a MacBook Pro. Good times.
