Question

I have a 2018 iMac 27in and would like to know if the 16.4.2 (not AI) will work if I buy the two different dongles that Apple sells.

The first if from firewire to thunderbolt, then one from thunderbolt to thunderbolt 3.

Can anyone confirm that this will work before I spend $150 on dongles?

Answer 1

Using 2 adapters

Apple (Thunderbolt 3 -> Thunderbolt 2 ) Adapter plugged into the Apple (Thunderbolt 2 -> FW800) Adapter will work yes.

Answer 2

Apparently yes:

 I will order the dongles and report back.
