Mac Client Hard Freezing with 4.0.5432

[j15big]

The WoW client will hard freeze whenever I login and have zygor turned on. I've deleted the WTF, Cache, Interface and Data>Cache folders and tried just installing zygor, same issue. All other addons work fine. The game runs fine when zygor is not installed. How can I fix this? Any tips?

*Edit:
Assuming this isn't going to get fixed tonight. How can I go back to the older version that worked so I can still play?

Only way to go back to an older version is if you have a zip archive of the older version.

Does it freeze if you have all other addons disabled and Zygor the only one enabled?
