That helped, indeed.

That's the first difference to my traces. Locally, I have here

shadow-add-to-todo: ((/tmp/shadowfile-tests0mPIFq . /cluster2:/tmp/shadowfile-tests0mPIFq)) nil

So you have a nil value of `shadows' in that trace. Looking at the code,
I see that `file-truename' is used to compute `shadows'. That rings a
bell - `temporary-file-directory' on macOS is located on a symlink. I
ran into this trap earlier already.

I hope, that my fix, pushed to master, fixes this now.
