On MacOS X use the command line utility "hdiutil" (see man page) to
convert to .iso, shoot that file over to FreeBSD and then use either
burncd or cdrecord.
Open a Terminal window on MacOS to get a shell then do something like
% hdiutil makehybrid -o my.iso my.dmg -hfs -joliet -iso
For some reason the above with -hfs generates a .iso file which mounts
when double-clicked but an icon does not appear on the desktop. It may
have something to do with the particular .dmg file I used. However
double-clicking the .dmg file appears on the desktop as expected.
Remove -hfs from the hdiutil command and the default appearance is
different than .dmg but otherwise produced a desktop icon for the
mounted volume as expected.
Normally MacOS X mounts .iso files as a volume when one double-clicks,
and the icon appears on the desktop. But not with the .dmg file
converted to .iso with -hfs that I was playing with just now. It
mounted but without the desktop icon. Was listed in /Volumes/ and with
df(1). Had to use "hdiutil detach /dev/disk6s2" to get rid of it. Or
logout/login did the trick as well.
