Talk:Install

I was willing 2 try zfs on MacOS but when I saw u need to set verbose flags "to make your kernel panics more useful"... So it's not a matter if this software has some issues, IT'S TOTALLY SURE IT WILL BE KERNEL PANICS ON A FILESYSTEM LOW LEVEL SERVICE!!!

Don’t worry, apart from this problem, which can be easily worked around, I haven’t experienced any crashes, yet. – Fnuxus (talk) 13:12, 16 April 2020 (UTC)

Uninstall before upgrade?

The instructions are not clear on if you need to uninstall before upgrading O3X. (They are clear that you must uninstall if upgrading from a different distro.) Anyway, I upgraded from 1.4.5 to 1.7.2 without uninstalling, and it seems to have worked fine.

Problems installing on Mojave

I followed the instructions on Mojave, and some things seem to be diffent there.

sudo nvram boot-args="-v keepsyms=1"

did not work.

Mymachine:zfs nemo$ kextstat | grep lundman
Mymachine:zfs nemo$ cd /System/Library/Extensions
Mymachine:Extensions nemo$ sudo kextload spl.kext

Trying to run zfs:
