The 23 GB file for Mac PoE v.4 never gets past the "verifying" stage when you double click on it. I am not using the Galaxy client.
23 GB?! Holy crap, I didn't realize it was that big. My Mac update from 3.x to 4.x was over 7 GB and I thought that included the whole game all over again. Did you want to try using the Galaxy client?
