Fnuxus:

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 [https://openzfsonosx.org/forum/viewtopic.php?f=24&t=3409 this problem], which can be easily worked around, I haven’t experienced any crashes, yet. – [[User:Fnuxus|Fnuxus]] ([[User talk: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.
