yes, that is right. 

As far as I can tell Skim always converts `.ps` files into PDF before it displays them. `gv` handles `.ps` files natively.

“Typeset & View (PDF)” does not use `gv`, but converts the `.ps` file into PDF. That is, why it is able to use Skim or any of the other PDF previewers. We could use this approach in “Watch Document” too. 

Do you think that would be a good idea? Can anybody think of a drawback of the additional conversion (except for the higher CPU usage)?

Interestingly, I had the same error before I wrote my reply. I solved it by reinstalling `gv`:

    brew reinstall gv

Maybe that helps in your situation too.
