Uninstalling the Official Release

If you have the folder Docs & Scripts from when you installed, go there, otherwise open the Open_ZFS_on_OS_X_x.y.z.dmg file you downloaded when you originally installed. If you no longer have the .dmg file, you can re-download it, on the Downloads page.

Open the folder Docs & Scripts.

Find the file named uninstall-openzfsonosx.sh.

Open Terminal.app. You can open it from Spotlight, or from the folder in Finder /Applications/Utilities.

Close all open files from your pools.

Export every pool.

sudo zpool list

Then for each pool listed

sudo zpool export $poolname

Verify all the pools have been exported.

sudo zpool status

Now drag and drop the file uninstall-openzfsonosx.sh onto your Terminal window, and press return.

Or just type

/Volumes/OpenZFS*/Docs\ \&\ Scripts/uninstall-openzfsonosx.sh

and press return.

You will be prompted for your password. Enter that.

The script will run and uninstall o3x.
