Hello x2go mac os lion users, here is a workaround for using x2go client on os x lion:

1. Download and install OpenNX Client for Mac. (http://sourceforge.net/projects/opennx/)
2. Inside the opennx...dmg right click the OpenNX.pkg and click "show package content"
3. Doubleclick Contents/Archive.pax.gz
4. Go inside Archive/Library/OpenNX
5. Copy "bin" + "lib" + "share" to your clipboard (cmd-c)
6. Go to your x2goclient.app
7. Right click the x2goclient.app and click "show package content"
8. Go to "Contents" folder
9. Paste your clipboard inside this folder
10. Copy the content inside the "bin" folder to the "exe" folder (nxproxy will be overwritten)

Now you can start x2goclient and connect to your server. If you get this error: "Invalid MIT-MAGIC-COOKIE-1 key" click on X11, start a terminal an type "xhost +localhost".
