A possibly related issue. I can save presets from the H3000 plugin interface, to the directory ~/Documents/Eventide/H3000 Factory/Presets (where ~ is my home directory).

I should also be able to save presets from DP's wrapper around the plugin. DP wants to save presets to ~/Library/Audio/Presets/Eventide/H3000 Factory. This is the location that corresponds to the "Reveal Presets In Finder" command in DP's preset pull-down menu at the top of the plugin window.

But when I try to do this, I get the following error: OS error reported by File I/O: There is no such volume (-35).

That filesystem path definitely exists on my computer, but the save operation seems to want to go to some nonexistent path.

Again, not a big deal, because I can save presets to the location that H3000 knows about.
