Hi,
I bought a font a few years ago for my Windows machine - it came in a
Type 1 postscript format, consisting of a .pfb file and a .lwfn file.
I have since moved over to a Powerbook with Mac OS X. I attempted to
put the files into the font folder, but they do not show up as usable
fonts - from what I can gather some kind of conversion is required
into a form of Type 1 suitable for OS X. How would I go about this? I
don't have more than $20 to spend on software/tools etc.
Thank you for your time.

It says at this site
http://groups.msn.com/fontlab/general.msnw?action=get_message&mview=1&ID_Message=5186
that a Type 1 font on Windows uses the .pfb file while the Type 1 font
on the Mac uses the .lwfn file.  Does it successfully install in OS X
and you just can't use it?

Yep, you're right - .lwfn is a Mac format. However, it seems to need a
.ffil too (.lwfn is for printers, .ffil is for screens.

See here PDF here: http://images.apple.com/pro/pdf/L311277A_FontTT_v4.pdf

Sadly I don't have a .ffil file (I certainly don't remember getting
one), so I guess I won't be able to use the font.

Thanks
