No. Other folks have spoken to the MacOS partitioning aspect. I'll address
teh ffs-specific part. :-)

An ffs can have up to 2^31 blocks. Note that these are the fragment size,
not what you'd normally think of as ffs blocks. For instance, on an 8k/1k
ffs, you can have 2^31 of the 1k blocks. :-)

Thus the max filesystem size is:

Frag size		fs size
512 bytes		1 TiB
1k			2 TiB
2KiB			4 TiB

and so on.

Take care,
