Trouble opening WotLK on MAC OS X el capitan 10.11.6

Whenever I try to launch the application I get "You can't open the application " world of warcraft" because PowerPC applications are not supported."

It was working fine yesterday and the day before, but today I restarted my computer and its not working anymore. Ive tried everything, currently reinstalling WotLK, but i have a feeling it won't work.

I am on a MAC OS X 10.11.6 el capitan

Any help would be greatly appreciated, I just want to get home after work grind out my paladin.

I've tried everything.. I've literally read through every single thread about mac issues with WoW... i tried this one yesterday and it didn't work. but I just tried it now and it worked i think because i reinstalled the game... I didn't want to reinstall the game because this will be the 3rd time i reinstall.. but at least its working now...

I have a 1TB External Hard Drive... is it possible to run the game off of that?

Thanks again
