I really don't have much experiencec with Macs, so I couldn't
tell you what CD formats they can read.  But from my experience
with burning CDs, I would recommend using Joliet.  Basically,
the wat Joliet works actually does not invalidate the iso9660
8.3 filenames; it just provides alternative long filenames that
a Joliet capable OS uses instead of the 8.3 filenames.  If a
Joliet CD is used in an non-Joliet capable OS, it will just
fall back on the 8.3 filenames.  I have never actually seen a
Joliet CD in a non Joliet capable OS, but I would guess it may
look a little different than normal, with extra files and such,
but I think it should be completely usable.

Here's a quote from the mkisofs man page about Joliet:
  -J  Generate Joliet directory records  in  addition  to
      regular iso9660 file names.  This is primarily use-
      ful when the discs are to be used on Windows-NT  or
      Windows-95  machines.   The  Joliet  filenames  are
      specified in Unicode and each path component can be
      up to 64 Unicode characters long.  Note that Joliet
      is no standard - CD's that use only  Joliet  exten-
      sions  but  no  standard  Rock Ridge extensions may
      usually only be used on  Microsoft  Win32  systems.
      Furthermore,  the  fact that the filenames are lim-
      ited to 64 characters and the fact that Joliet uses
      the  UTF-16  coding  for  Unicode characters causes
      interoperability problems.

Again I want to point out that I basically have no Mac experience,
but as I was reading over the mkisofs man page, I noticed a
section on "HFS Macintosh File Formats" which seems to describe
a Macintosh parallel to Joliet.  I really don't know what HFS is,
but it might be something you want to look into if you plan on
making a lot of hybrid CDs.  See the man 8 mkisofs page for more
details on HFS or Joliet.

Hope this helps more than it confuses,
