Firewire connection Sony to mac mini 2012: DCR-HC20 iLink setup for DV out

I am trying to transfer some old miniDV home footage shot on my DCR-HC20 and would really like to use iLink to maintain the footage quality.  I am connecting the camcorder to my mac mini computer via iLink, but have been unsuccessful in having the computer detect the camcorder. I have tried everything on the computer side with no success (reinstalled multiple versions of macOS, new iLink cables, and various startup connection sequences. None have made a difference. 

I have however read multiple user posts with similar issues, with other model miniDV camcorders, saying to make sure the camcorder is NOT set to DV in.  

In my case however when connecting the DCR-HC20 the display does show "DV in". I have searched everywhere in the Sony Users Manual, but have not found how to change that to DV out.  

Has someone run into this issue and has a procedure how to set iLink connector to DV out???

Any help would be greatly appreciated
