Note you need the existing Mac Lamannia client to attempt this. I am not sure how one goes about getting it anymore.
If you have it:
The Mac Lamannia Launcher hangs at the very first screen saying "Installing Prereqs". It eventually crashes.
If you run it a second time, it gets to the progress screen but has the message:
"Failed to Initialize or Install Akamai NetSession Interface"
If you find and install Akamai NetSession Interface for Mac manually (here is a link I found: https://a248.e.akamai.net/client.aka...=installer.dmg), and run the Launcher for a third time, then the Lamannia client will download.
The Lamannia client did eventually download. I am running round 6 now. The Mac damage display bug is still there. I assume the clipping one is too. I leveled a sorc up to 28, but without gear or twists, she doesn't survive long.
The DDO store doesn't work, so I can't play the new content.
