Macintosh

I'm getting a blank character select screen after I login after the mini patch today. I've tried rebooting, multiple accounts, clearing cache, with no luck. I've found mentions of similar things happening in the past, but no concrete steps on how to fix it. Can anybody help? A post a week ago mention a repair tool. I know where that is for windows, but no idea how to run it for the mac client

update: finally found the verify tool and that was able to fix the problem
