How do you enter cheat codes for mac? I have put the code "Debug Mode=1" in the ini file but I dont know how to get up the console window to activate the cheat codes. Pressing Ctrl+Space doesnt work. Can anybody help me?

(If this doesn't work in your game, write Cheats=1 under [Game Options] instead.)

I assume your running OSX and I bet you used Text Edit to enter the cheat in the .ini file right? Text Edit doesn't work for entering the cheat code in the .ini file for some reason (doesn't save it properly). Try using simple text in classic or something else.
You have to enter this exactly 'Debug Mode=1' (without the quotes) on it's own line under Program options.
To activate the console in the game press Control+Space bar.
Go here for more info: http://ire.mainecoon.net/ . It's a link to a Macintosh/Baldurs gate site with stuff like mods and cheat codes.

Hope that helps....
