Sketchup Pro, Mac, Datasmith, direct link "No Connection"

[AndyGrandCentral]

Hi all.
I cannot establish a connection bwteen Sketchup Pro and Twinmotion.
I have searched forums, uninstalled both Sketchup and Twinmotion, Reinstalled fresh, restarted but to no avail.

Some specs:
Macbook Pro M3, Sketchup Pro 2024 (up to date), Twinmotion 2025.1.
Working locally with everything saved in the same folder on desktop.

Both programs are open but SketchUp says it is waiting for a connection and Twinmotion says “no source available”.

2 hours in and I am stumped.

Yes, I can bring in the sketchup file directly but I am not convinced I am finished amending and there will be client amends so I want to get this all up and running now.

Any ideas welcome. What have I missed?

Thank you

WORKAROUND…

Export the Datasmith file from Sketchup.
Import the Datasmith file using the Geometry setting.

If a change is made to the original Sketchup file, re-export the Datasmith file and refresh the imported datasmith file within the Twinmotion import.

This refreshes the model without losing materials or any other changes already made within Twinmotion.
