Hi, thanks for the report.

I’m not on 10.13 yet, so I can’t test this. Is it only .tex files that
don’t work?

When double clicking a file it should open in an existing Emacs
instance even without a server process.

Do you have more than one Emacs.app installed? Is it possible you need
to re‐associate .tex files with the correct Emacs? (Get Info ‐> Open With)
