What is portmap and why does Wuala need admin rights to set it up?
In order to enable direct file access on Mac OS X, portmap (a service of Mac OS X) needs to be running. Wuala can automatically start portmap und configure it to start automatically on startup. However, admin privileges are required to do so. So When enabling direct file access, you will be asked for your admin password. If you prefer to do this manually, just copy the file com.caleido.portmap.plist that can be found in the Wuala application bundle to /Library/LaunchDaemons/ and restart your system.
