Mac gamers will find these problems to be a constant pain in the ass inconvenience. No, you can't update. Instead, you have to cancel the update dialogue and click "Repair". Once you're done (it may fail), get out of pslaunch and start psclient. PS will only open from psclient for Mac OS.

Thanks for reply.
so there is no way to 'INSTALL' the game 'normally' ?

Hello guys,
I'm newbie here and for Planeshift. Yesterday I download the Mac version from official site: Planeshift_._it, that's a dmg file named "Planeshift-v0.5.9.2.dmg". But it turns out there's no installer or installation package shows out when I mount the 'dmg' file.
The 'dmg' contains a folder named 'Planeshift', and the folder contains some subfolders and files.

Now I can enter the game just double click a file named 'psclient'.

And I can go into the preload(setup) section when I double click a file named 'pslaunch', but I cannot get update and cannot enter the game from here. Everytime I try to do so the game crashes.

I've seen the README file and learned that something maybe wrong with the 'dmg'. How should I do? By the Way, I downloaded it again from another mirror site, still........

Any help and suggestions should be welcomed!
