Solved: I finally solved the problem. Apparently some mac users have had this issue with other games as well. We get stuck somehow with an old version 6 of Java that doesn't get updated with the newer versions. This forum page from another game gave me the solution: https://www.wakfu.com/en/forum/36-techn ... configured
At the bottom it has a link to a JDK8 download of java and after downloading and installing I can use the Ender updater to get H&H up and it let me log in to create a new character! (Amber might work as well, I have not tried it)
Mods: H&H has always been one of those games to give macs a hard time so if mods can spread the word when maccies ask for help, we'd be grateful.
