When I open up LSL1, the screen is situated in the bottom left corner of my monitor - how do I edit the settings for Mac? I'm new to Mac gaming, but since I'll be on a flight and my Mac actually has a decent battery life, I thought I'd give it a go.

Thanks for the help!

Well since Larry 1-5 and the VGA version of Larry 6 use Scumm(the SVGA version of Larry 6 is using dosbox/boxer) you can try and play with the settings by starting the game and then when the starts hit Ctrl +f5 this should bring up the Scumm VM menu just click the option marked "return to launcher" this will take you the main scumm vm launcher menu from there just select the game and click the edit button you should be able to play around with the settings there.
