Hmm. I'm not using mac, but I do use Chrome. And the only difference there is it is build 160 vs 159. Are you using any extensions?
Of course, the obvious, have you cleared cookies/cache?
Tried logging out completely, clearing/closing browser, then logging back in with "remember me" checked?
I'm not trying to be condescending, but the more information as to what has been tried might provide some insight into the issue.
