It's more likely the FFIL file is a font suitcase, containing the  
screen fonts in either bitmap or TrueType format; that's used in  
Classic for screen display and non-PostScript printing. The LWFN files  
contains the printer fonts, in PostScript format, used for printing to  
PostScript printers. I don't think there's anything OpenType here.

There are instructions at  
<http://homepage.mac.com/bkerstetter/tex/fonttutorial-current.html>  
(look at Font conversion/Classic font files, use t1unmac).

As to how to use the fonts once they're available as .pfb files, some  
of the work is already done in teTeX for the fonts MathematicalPi Two  
and Six (as remarked Peter Cholak in a earlier post on 29 June):

- .tfm files mh1.tfm tp mh2.tfm inside  
/usr/local/teTeX/share/texmf.tetex/fonts/tfm/yandy/mathpi/

- .map file /usr/local/teTeX/share/texmf.tetex/dvips/misc/mathpi.map  
containing entries for mh2, mh2scr and mh6

- .fd files umh2.fd, umh2scr.fd and umh6.fd, and .sty file mathpi.sty  
inside /usr/local/teTeX/share/texmf.tetex/tex/latex/mathtime

- doc for the mathpi package as section 2 of  
/usr/local/teTeX/share/texmf.tetex/doc/latex/mathtime/mathtime.dvi

This means putting in your LaTeX documents

	\usepackage[mathfrak,mathscr,mathcal,mathbb]{mathpi}

will define commands \mathfrak, \mathscr, \mathcal and \mathbb to use  
characters from MathematicalPi Two and Six.

Should you want to use the other MathematicalPi fontd (One, Three, Four  
and Five), you'll have to create files:

- in ~/Library/texmf/dvips/misc/, a file mathpiplus.map say containing:

	mh1 MathematicalPi-One <mh1.pfb
	mh3 MathematicalPi-Three <mh3.pfb
	mh4 MathematicalPi-Four <mh4.pfb
	mh5 MathematicalPi-Five <mh5.pfb

- in ~/Library/texmf/tex/latex/mathpi/, files umh1.fd, umh3.fd, umh4.fd  
and umh5.fd containing stuff like:

	\DeclareFontFamily{U}{mh1}{}
	\DeclareFontShape{U}{mh1}{m}{n}{<->s * [0.95]mh1}{}

- in ~/Library/texmf/tex/latex/mathpi/, a file mathpiplus.sty say  
containing stuff like:

	\DeclareMathAlphabet{\mathpione}{U}{mh1}{m}{n}
	\DeclareMathAlphabet{\mathpithree}{U}{mh3}{m}{n}
	\DeclareMathAlphabet{\mathpifour}{U}{mh4}{m}{n}
	\DeclareMathAlphabet{\mathpifive}{U}{mh5}{m}{n}

Then you'll have to run in Terminal:

	sudo updmap --enable Map mathpiplus.map

put in the preamble of your LaTeX document

	\usepackage{mathpiplus}

and you'll be able to get characters from MathematicalPi One, for  
example, by writing

	$\mathpione{abcdefg}$

It's all untested by me, but I hope it should help nonetheless. In  
particular, it's possible you can't load that many math alphabets at  
the same time. In that case, you'll have to implement loading these  
alphabets as options to the mathpiplus package, as is done in  
mathpi.sty, by replacing its content by

	 
\DeclareOption{mathpione}{\DeclareMathAlphabet{\mathpione}{U}{mh1}{m}{n} 
}
	 
\DeclareOption{mathpione}{\\DeclareMathAlphabet{\mathpithree}{U}{mh3}{m} 
{n}}
	 
\DeclareOption{mathpione}{\\DeclareMathAlphabet{\mathpifour}{U}{mh4}{m}{ 
n}}
	 
\DeclareOption{mathpione}{\\DeclareMathAlphabet{\mathpifive}{U}{mh5}{m}{ 
n}}
	\ProcessOptions

and loading mathpiplus in your LaTeX document in the form (for example)

	\usepackage[mathpione,mathpithree]{mathpiplus}
