I run a OS X 10.8.5 guest on top of OS X 10.8.5. Works amazingly well, so far it feels like running directly on the hardware. I use Parallels Desktop 10. I want my VM to be fairly isolated, at most sharing a special folder between host and guest and be able to do copy/paste of text. The option "Actions -> Configure.. -> Security tab -> Integration: -> Isolate Mac from virtual machine" then creates a bit too much isolation as copy/paste will not work between host and guest. So I then disable the complete isolation and go to "Actions -> Configure.. -> Options -> Sharing" and set "Share Folders: None" and "Custom Folders:" to a special controlled folder. So far so good, the folder turns up in "/Volumes/SharedFolders/". But in addition in "/Volumes/SharedFolders/" I also have the folders "Dropbox", "Google Drive" and "iCloud", things I don't want shared. Note that I haven't installed those in the Guest OS. I tried disable "SmartMount" but it makes no difference. So do you know how I can keep copy/paste and maybe a shared folder without also sharing "Dropbox", "Google Drive" and "iCloud"? Is this a bug, should disabling "SmartMount" prevent them from being mounted in the Guest? Thankful for any insight on this.
