Re: ' Disc authentication failure' Problem

For Macs, this seems to be one of the ongoing issues. Some people have reported getting it because of custom download or even Store.

Try moving the folder DCCache in the user files (don't know where they are on a mac) to the desktop and start the game to see if it works. If it doesn't, put the folder back and report back. If it does you need to find out what content is causeing the conflict.
