Sharing from host OS X doesn't work with guest Linux (NixOS 17.03)

I've tried all possible options, but there are still no mounted folders or mountable devices in the guest OS. How is that expected to work?

I'm using parallels desktop pro 12 on OS X and NixOS 17.03.

My settings can be seen on these screenshots:

I've restarted the VM a few times, but to no avail:

Did you install Parallels Tools inside the guest?

 

Idem issue for me. Fedora 25,26 folders and files are looked
