Those are fonts for windows. If the font license allows it, they can
be converted to Mac Type 1, or to Opentype, for use on the Mac.
If you're ONLY using them in Adobe Products, I understand that they
can be used on the Mac if they're put into an Adobe-specific fonts
directory. I don't know exactly how or where (I'm a PC user), but
someone else here, or possibly in one of the application-specific
forums can help with details (e.g. for CSx or InDesign or Illustrator).
