Thanks Minmay,
Boy, Mac does not make this easy. After further effort, I was able to unhide the folders and get to the Legend of Grimrock folder and open the CFG file with sublime text. I changed console from false to true (the console key was already at 220. So I originally changed console = false to console = true, saved the file, launched grimrock, press \ and nothing. Press / and nothing, press ~ and nothing. So I figured the window sizes were bad, so I adjusted the file further, and still nothing:
console = true
consoleKey = 220
windowPosX = 10
windowPosY = 10
editorWindowPosX = 10
editorWindowPosY = 10
editorWindowWidth = 80
editorWindowHeight = 42
I am at a loss as to why this is not working yet. Sorry I am such a pain. Thank you all for your efforts!
