so i just downloaded the World of Warcraft (legion models) on my macbook pro for the second time this day and it keeps showing the same message after i end the download and start the game.
"World of Warcraft was unable to start"
in additional information to that, every icon in the folder i just download are overlapped with a restriction sign idk what that means but i should be something to work with.

any ideas how to solve this?

thanks for the help.
