OpenZFS on OS X

I've successfully installed the new 1.6.0 Sierra RC1.pkg over an existing 1.5.2 dmg installation. Only issue was that the installer failed with being unable to load kexts, but following a reboot after first running, I was able to rerun the installer and complete the installation. Further reports as I turn anything else up. SIP disabled.

Cheers and thanks for all your hard work people! Much appreciated as ever.

Similar experience here: After exporting my zfs pool, I was able to install 1.6.0rc1 without problems (10.12.2).
kext loaded correctly, but zpool wasn't able to find and import my pool again until I rebooted.
Then all was fine.

Many thanks to everyone involved!!
