I am a self-admitted Mac fanboy, but just couldn't wait for Pillars beta. So I decided to reboot into a YEARS old BootCamp partition. I think its running some old copy of Windows7. I honestly have no idea. (Steam was already on it from when I decided to replay Diablo2 one time). Anyway, Steam took a long time to update, but eventually worked. PoE linked to my account fine, and I downloaded the beta.
Didn't get much further than character creation though...crashed several times (all during character creation). One time I got into the game, but crashed shortly after walking around a bit. I have a few crash dumps somewhere on my machine, but I'm not sure where it saved them. If it would help, I'll happily go track them down, but I probably should just wait for the Mac version, yeah?
For example, this crashes everytime:
1) Human -> next
2) Meadow Folk -> next
3) Click Wizard (pauses a sec)
4) Click Chanter (pauses, then BOOM....every time).
I don't know if its useful though, as I probably am using a very ill-advised setup! (As I said, just couldn't wait!).
Everything I saw looked amazing though! Looking forward to the OSX version!
