Query: Doesn't work with Mac

I loved MIST & RIVEN and couldn't get MYST III fast enough. After years in the software business I should have known better than to purchase version 1.0. If you have a MAC, I suggest you wait several months, years? until Ubisoft corrects all of their problems. For now, I am stuck with a game that is unplayable due to visable grid lines, very jumpy mouse control and choppy speech. Ubisoft answered my email saying that they will get back to me in 24 hours. That was 10 days ago and I am still waiting. I hope ... will return my money.
