Lego Digital Designer 2.3.15 Macintosh

HI,

They changed the requirements for LDD 2.3.15 so it won't work with
MacBooks or Mac Minis because they use Intel's integrated graphics
processor.  I think I had version 2.3.13, which worked fine on my
MacBook.  I emailed Lego and they said they can't send me an older
version.

Does anyone know were I can get it an older version of LDD?

thanks
Jeff
