What you see is normal: all the support files for the MathTime Basic  
fonts are included in gwTeX (.fd, .sty, .tfm, .vf, .map files),  
together with public-domain clones of the fonts called belleek. It's  
these clones that you are seeing, and as you observed they are not  
quite the same.

What you need to do (see also the simpler alternative at the end of  
the message):

- In Terminal:

	sudo -H updmap-sys --disable mt-belleek.map

- Convert your MathTime font files in the LWFN format to PFB format,  
as explained in section 3 of <http://www.tug.org/mactex/fonts/ 
fonttutorial-current.html>. Specifically, I just re-tried the  
conversion (in Terminal again) and it works (I copied the LWFN font  
files into a folder Test on the Desktop):

	legimc11:~ brunovoisin$ cd /Users/brunovoisin/Desktop/Test/
	legimc11:~/Desktop/Test brunovoisin$ ls -l
	total 136
	-rwxr-xr-x   1 brunovoi  staff  0 May 17  1993 MTEX

	-rwxr-xr-x   1 brunovoi  staff  0 May 10  1993 RMTMI
	legimc11:~/Desktop/Test brunovoisin$ t1unmac -r RMTMI/rsrc rmtmi.pfb
	legimc11:~/Desktop/Test brunovoisin$ t1unmac -r MTSY/rsrc mtsy.pfb
	legimc11:~/Desktop/Test brunovoisin$ t1unmac -r MTEX/rsrc mtex.pfb
	legimc11:~/Desktop/Test brunovoisin$ ls -l
	total 264

	-rw-r--r--   1 brunovoi  staff  20732 Jun  7 11:20 mtex.pfb
	-rw-r--r--   1 brunovoi  staff  19483 Jun  7 11:20 mtsy.pfb

You need the utility t1unmac, included in gwTeX already. The odd  
syntax (-r option, suffix /rsrc to the font file name) allows t1unmac  
to access the resource fork of the LWFN file. Be careful when using  
uppercase and lowercase in file names, TeX and its friends on OS X  
are case-sensitive, because of their Unix inheritance.

- Create a directory /usr/local/teTeX/share/texmf.local/fonts/type1/ 
yandy/mathtime/ and move the PFB files into it. What you can try, in  
Terminal again:

	cd /usr/local/teTeX/share/texmf.local/fonts
	sudo mkdir type1
	cd type1
	sudo mkdir yandy
	cd yandy
	sudo mkdir mathtime
	sudo mv ~/Desktop/Test/*.pfb mathtime/

There may be more efficient ways of doing this (less steps), but as  
you can see I'm not a comand-line person.

- In Terminal:

	sudo texhash
	sudo -H updmap-sys --enable Map mt-yy.map

- I was about to forget: the plain TeX support file mtmacs.tex isn't  
included in gwTeX. In case you're using it, copy it from its original  
TeX Input location in Textures to /usr/local/teTeX/share/texmf.local/ 
tex/plain/mathtime/, running "sudo texhash" afterwards. I' m not  
sure, but it's also possible that you need to get the file  
texnansi.tex in addition, and add "\input texnansi" in your plain TeX  
files using the MathTime fonts. texnansi.tex wasn't included in the  
Blue Sky MathTime floppy, but it was on the Lucida floppies.

Given you're using the Blue Sky distribution of MathTime, I guess you  
don't have the MathTime Plus addition (with bold maths etc.). If you  
did, though, then you would need to repeat the conversion from LWFN  
to PFB for this addition and then run:

	sudo -H updmap-sys --enable Map mt-plus.map

All these map files (mt-belleek.map etc.) live in /usr/local/teTeX/ 
share/texmf.tetex/fonts/map/dvips/tetex/.

Now, as announced earlier, an alternative: get the complete MathTime  
font set from Personal TeX, which is now their distributor <http:// 
www.pctex.com/mtpro2.html>, given that Y&Y, their original  
distributor (Blue Sky Research was only a reseller), has closed  
<http://www.tug.org/yandy/>.

Similarly, in case you are using the Lucida fonts, you can either  
perform the conversion from your original Blue Sky Research floppies,  
or better get the complete fonts in the proper format from either TUG  
<http://www.tug.org/store/lucida/> or Personal TeX <http:// 
www.pctex.com/Lucida_Fonts.html>. In this case you'll also get  
updated LaTeX support files (replacing the lucidabr package).

In the long run, regarding the MathTime fonts, it's possible they are  
simply superseded by the STIX fonts <http://www.stixfonts.org/>, when  
these become finally available with full TeX support.

On other matters: *please* don't contact me personally except when  
absolutely necessary, and refer to the OS X TeX list instead. I'm  
really short of time, and more and more people seem to want to  
contact me directly for TeX matters: I simply can't provide this  
service, due to real-life job obligations (see the signature below).  
Sorry. In addition, solutions useful for someone may also be useful  
to others, and it's accordingly better to make them available through  
the list.
