Thunderbolt 2 dock connection to a Thunderbolt 3 iMac
I'd like to connect my MacBook Pro (15-inch, Mid 2012; running 10.14.5 OSX), to a Thunderbolt 2 hub/dock; and then connect the Thunderbolt 3 cable with the adapter from the TB2 dock to an iMac's (2017, 27") TB3 connection. Will that work? My local reseller said no but I don't understand why when the TB3 cable is using a TB2 adapter to connect to the dock. Thanks for your help.
