Thanks for info.  This is mostly for a one-off copy, largest files are 
~200MiB .wavs, plus some .mp3s, .png spectrograms and several programs, 
not too big for FAT32, neither will be a say 96GiB partition, though 
I'll need to limit any compreesed archives to <4GiB on FAT32.

Considering how BSD-ish it seems in Terminal - df, du and other commands 
working as expected - I was a bit surprised that it doesn't support UFS 
natively, given its heritage.  When I first ran mount it complained - as 
will FreeBSD without an fstab entry - about needing the -t switch, but 
'mount -t ufs' didn't complain about that but a (not) missing directory.

Thanks for the method .. ssh access was shaping to be my next question, 
sftp -p likely being the quickest short-term solution here, and I won't 
need to scare my daughter by messing around with her precious Macbook :)

cheers, Ian
