If you find, especially with the original CDs, that running the installer fills your screen with a white box, which doesn't change, do the following:
Command + Option + R to restore your screen
Quit Crossover
Re-launch Crossover
Go to Configure -> Manage Bottle
Select the bottle you wish to install into
Select the 'Control Panel' tab
Launch 'winecfg'
Select the 'Graphics' tab
Check off 'Emulate a virtual desktop'
Enter in a size (1280x800 works for me)
Try installing Renegade again
Crossover will resize the desktop if it needs to, based on program requirements, so don't worry about it!
