If you wish other users to see and access your mounted volumes when Fast User Switching is used, you need to:

  1. Use the site version of CloudMounter.
  2. Install one of the following versions of FUSE for OS X.
  3. Check the “Make this drive visible to other accounts on this computer” option.
  4. Switch to the macFUSE Drive type of drive mounting.

Volumes mounted with the Mac App Store edition of the software are not displayed to other users under no circumstances.
