Yaesu 450D - what cables do i need

Hi, I’ve just purchased a new digirig mini to connect my 450D to my MacBook. After reading the post Yaesu FT-450D setup issues. I’m a bit confused about cables and where to get them from. Initially i made my own mini 6 pin to two 3.5 jack plugs. This seems to receive ok but TX is very hit and miss with almost nothing on FT8.

Hope this makes sense.

Thanks

Roger, here is the info on cables and settings:
