This is not the first time I've heard of one OS having problems with
another OS' instantiation of UFS.  For the particular application at
hand, I'd use tar(1) to collect the files into a single stream and
write the tarfile onto a USB key formatted as FAT32.  OS X should
have no trouble reading a FreeBSD tarfile.
