Hi! I'm running OS/X 10.5 (Snow Leopard) on a recent high-end iMac. I recently got Avadon in the Humble Bundle, installed my steam key and got it set up. Whenever I try to run it, nothing happens - I get the litle steam box which says "Preparing to launch Avadon" but then the box closes and I'm back to where I was before.
I've tried a bunch of things before posting here. I've uninstalled and reinstalled the game a few times. I've checked software update and there are no updates available for my Mac. I can't see an obvious way to reinstall my video card drivers short of Software Update (I've just got the regular old video card which came built-in to the Mac, an ATI Radeon HD 5750). I've checked the support page for Avadon but nothing there is relevant.
Any advice? Is there somewhere I can look for log files or something similar?
