Hi, I just bought the sims complete collection for my new iMac, I'm new to MAcs so sorry if this is a silly question. I'm just wondering how to change the resolution of the game? On Windows XP you selected the resolution before the game started but not on the OS X version. I've looked in the preferences but it only lets me choose between full screen and windowed mode, the resolution change box is de-highlighted for some reason. Anyone know how to change it? Thanks for any advice.
