Food,
I just looked at the system requirments for the
NutraCoster software I have. It only reads for 32-bit Windows including Windows 98 , Windows 2000, Windows ME, Windows XP or later.
nutraCoster Professional 2.1 will not run under Windows 3.1, Windows 95 or Windows NT.
I know absolutely not a thing about Mac so use the link if you believe you can get something to work for you.
Good Luck.
