On OSX El Capitan, after a fresh install of Fuse, I can create a new project, either example, fuse or new, directory selection is working and files are created. But after that nothing happends, nothing opens.
After project creation using the dashboard you should be taken to a screen that looks like the following:
Is this not the case?
Same here 
For anyone seeing this issue: Do you have a Fuse icon in the tray? 
If so, please try to click it and select “Quit” (“Exit” if you’re on Windows). When you use the Fuse Dashboard again, this should make the service restart and usually solves the problem.
If that doesn’t help, you could try re-starting your computer.
You might also check your mono version (mono --version) if you’re on OS X. Fuse works best with the official, stable mono 4.0.4 which you can get from the mono download page. Make sure you click the top button, not on the “El Capitan Preview”, even if you’re on El Capitan, as that is a preview version of mono.
