WOW over UBUNTU 8.04 (MacBook Intel)

hello guys, im trying to run world of warcraft in my macbook so far i can play warcraft 3 and exp. but for wow i have lots of troubles. the installation i did was downloading the game from blizzard then i did all the tutorials about how to run wow with wine. if i run wow with opengl i got big black boxes and i cant type or click anything. but if i run wow with d3d i see everything normal after loging into my account i can change from servers . the issue comes when i enter the world with a char. i see the loading bar and the background image but from nowhere wow crashes and i get an unknown error. what i did to try to fix that was checking the regedit trick so far i cant play. pls some help :D i really dont want to go back to win XP. the last resource i will do is play on os x :S

Could you post the spec of your mac (including graphics card) and a copy of your config.wtf file located in your .wine folder.

Thanks
