Yes, I figured. I'm running on High Sierra for the moment, but was hoping to move to Mojave soon — that's why I'm testing it out.

I tried the 1/22/2019 nightly from emacsforosx.com, but tramp didn't work as expected. It reports its version number as 27.0.50 — is that the right one to try?

In the 26.1 pretest, I did:

  C-x C-f /scp:slc:

(slc is my remote hostname).

That produced the blanking behavior I described

But in the nightly, this just says that the directory is not found — seems to think I mean a local directory.

Did something change (again) about tramp syntax?
