Symptom:

You can connect successfully to your Filespace however you receive the error Failed to mount the filespace: Cannot prepare mount point with elevated permissions: child exited with 1 and you have no mount-point to access your data.

Problem:

Incorrect permissions on /Applications/Lucid.app/Contents/Resources/Lucid

Solution:

Open Finder -> Applications -> Utilities -> Terminal and type:

ls -al /Applications/Lucid.app/Contents/Resources/Lucid

Which should output something like:

-rwsr-xr-x 1 root wheel 22187792 6 Oct 17:02 /Applications/Lucid.app/Contents/Resources/Lucid

If the user is not root or there is just "x" instead of "s" (as highlighted in green) for the user permission triplet please correct the issue by typing:

sudo chown root:wheel /Applications/Lucid.app/Contents/Resources/Lucid
sudo chmod u+s /Applications/Lucid.app/Contents/Resources/Lucid
sudo chmod +x /Applications/Lucid.app/Contents/Resources/Lucid

open LucidLink client and try again to connect and mount your Filespace.
