growisofs and cdrskin hardly ever need a size prediction.
Nearly always there is a way to write a session without
previously announcing its size. (Except with fast blanked
DVD-RW.)
growisofs and cdrskin should be able to figure it out by
themselves if you do not force them. (I.e. no option
-dao with cdrskin, no -dvd-compat or -use-the-force-luke=dao
with growisofs.) 


growisofs is sometimes hard to stop from interpreting
an eventual ISO 9660 superblock.
So with ISO images, even -dvd-compat and -use-the-force-luke=dao
are ok.

There is also option -isosize for cdrecord, wodim, cdrskin.

In man cdrecord and man wodim i read:
"Do not use this  option  on  files  created  by
 mkisofs and in case cdrecord reads the track data from stdin."

In man cdrskin:
"This option can be performed on track sources which are regular
 files or block devices. For the first track of  the  session  it
 can  be performed on any type of source if there is a fifo of at
 least 64 kiB. See option fs= ."

It remains an open question whether the problems
with the wodim DVD+R are bound to the drive or
to the operating system.

Well, if you ever can boot that OSX hardware
under Linux ... :))


Have a nice day :)
