4 years ago - I didn't had this issue on my MacPro 5,1 with zpool on 3x HD. (ZFS v 1.8.x / 1.9.x)
- I have the reverse issue on my MacBook with a zpool on a vdev (file) see #756
- I don't have this issue if I do a
zpool export -abefore initiating shutdown (Note : in case of a vdev see #756 )

My Mac always hangs on shutdown when there are no pools connected: The screen gets black, the mouse pointer is still there and movable, but nothing else happens, even after hours of waiting.
I have known this problem for some years now, and it was the reason why I gave up on ZFS some years ago.
I solved this problem now by setting up a dummy USB thumb drive as ZFS pool with no data on it that always stays in one of my USB ports.
This does the trick, but it is not exactly as it should be, because things like that scare off new ZFS users.
