The compiled client with changes for Mac is now available, check link in Lopyrech's post.
You just have to copy the data folder from your normal Ryzom install (right-click on the program -> show package contents -> Contents -> Resources -> data) to the downloaded Ryzom, to the same place. The files mentioned in Lopyrechs post (widgets.xml and commands.xml) need to be copied to /Users/<user>/Library/Application Support/Ryzom/user folder. Have fun testing it out :D If you have any questions contact me.
I am too scared to do this let alone understand it, lol. I am afraid i will mess up my client if i try. I think i need a little hand-holding :(
