There will be a proper fix for this on Wednesday from Trion, we believe. We recommend waiting for that fix.
In the meantime, we have a very quick hack that will get you running right now if you like.
As I write this, the Linux fix is available; the Mac version should be available shortly.
To get it, go to:
http://dl.codeweavers.com
and enter a password of rifthack20110627
On Linux, download the ntdll.dll.so.rifthack.linux file and use it to replace either /opt/cxgames/lib/wine/ntdll.dll.so or ~/cxgame/lib/wine/ntdll.dll.so.
For the Mac, in about 15 minutes, a full DMG of CrossOver Games should be available; run that in place of your regular CrossOver Games. You will need to unlock it again with your username and password.
This build is almost completely untested. We threw it up and verified we could get into RIFT, but didn't test at all further.
Again, if you can wait until Wednesday, I would avoid this. But my wife and I meant to play tonight, so I'll be patching my box... 😊
Cheers,
Jeremy
