Multithreading on Mac OS X

I've recently read somewhere on the Web that Mac OS X has no concept of multithreadiing. I'm assuming from this that OS X uses some form of coarse-grained scheduling based on task/process. How does the Java VM run on OS X? Java apps rely on multithreading within the VM.

Thanks.

Tune it as you might, but the security of such systems is always more suspect than Mac OS X. One virus, and any optimizations you realize will be out the window (if you pardon the pun).

Its implementation may be different, but it does support it.
