Yeah same problem here.
I started the updater through the terminal commmand and the updater worked but after update nothing worked. I put all this on the mac forum but i guess it might help to post here too. I made a new copy of the Planeshift folder before the update, transferred all the stuff one by one to find that the vfs.cfg after update stopped the psclient and the updater to not start at all. And also the new updater application does not work either. So I put everything in the new folder except fo the vfs.cfg adn the updater application. Used the updater to update again and the updater stopped working again. But I tried the psclient and it started up fine, but it still says my current version does not match the servers. Hope this information helps fix the problem. Otherwise I dont\' have a clue what to do from here.
