I know - the only way we can make it "work" is to have both MBR 
partition table and GPT table.  These are in sync, so it shouldn't 
matter which one you get :-)

The only proper fix for this on Mac hardware is to make it all EFI boot 
properly, but I gave up on that last time I tried (admittedly >1yr ago, 
so it may be better now).  Apple don't support a full UEFI environment 
which is unhelpful.

Yes, this fixes it for 9.2 - I'll check 10 later but they both show the 
same problem so I think it will fix it.  Thank you very much.

What was the source change that fixed it?

Thanks very much for the help,

Paul.
