[asked what to do about MacIntosh]
Well, at the risk of looking foolish asking how you tested this: did you
try using the Mac without any 60Hz light sources nearby? Occasionally, the
combination of intensity flicker from lights (reflected off Mac) and the
internal raster aggravates the situation. Also, you might try working with 
the screen quite dim, so the contrast isn't so high, which means the
smaller contrast caused by raster is less noticeable.
Good luck. 
If anyone out there writes a patch to System6.0* for Macs which inverts
the application screens, I'd be interested for curiosity's sake.
