I think it means you can mount an EFS instance on OS X

No, it doesn't. From the announcement:

"Only Amazon EC2 instances within the Amazon Virtual Private Cloud (Amazon VPC) you specify can directly access your Amazon EFS file systems."

Yes, but NFS over the Internet may not be fast enough to be usable.

Back in olden times Linux installation floppies provided the option of installing from an NFS share.

We used to do it over 10Base-T, which is slower than a lot of residential connections now. Well, latency will be higher over the internet, but bandwidth will be ok.

That's the whole point. Since NFS is such a round-trip oriented protocol, it's very sensitive to latency. You'll never fill up the bandwidth unless you do large bulk transfers in parallel.

But you can only use efs with ec2, which doesn't support osx.
