First things first ‐ installing znapzend - xenophon61/Znapzend-recipes-for-mixed-MacOS-Linux-environment GitHub Wiki

MacOS running Sonoma 14.6.1

OpenZFSonOSX version 2.2.2

Homebrew install

znapzend installed via Homebrew with a simple brew install znapzend
apply the fix for the homebrew.mxcl.znapzend.plist, as outlined here*

Useful commands:

restarting the znapzend daemon (the "kill -HUP" doesn't work in MacOS)

sudo brew services restart znapzend

the error log can be found at

tail /usr/local/var/log/znapzend.err.log

checking the state of the daemon:

sudo launchctl list | grep znap

should return a status of "0"

41833 0 homebrew.mxcl.znapzend

Alternative (and, perhaps, better) installation option: straight from the znapzend Github

Download the git to your home folder, and then issue a sudo su

# ZNAPVER=0.22.1
# ./configure --prefix=/opt/znapzend-${ZNAPVER}
# make
# make install
# ls -la /opt
# for x in /opt/znapzend-${ZNAPVER}/bin/*; do ln -fs ../../../$x /usr/local/bin/; done
# znapzend --version
znapzend version 0.22.0

Remember to check the section regarding init scripts. For OS X one must use the launchd procedure as follows:

~ % sudo launchctl unload /Library/LaunchDaemons/org.znapzend.plist

~ % sudo launchctl list | grep znap

~ % sudo launchctl load -w /Library/LaunchDaemons/org.znapzend.plist

~ % sudo launchctl list | grep znap

System Preferences:Security to allow full disk access for the following

/bin/sh
/bin/zsh

/usr/bin/ssh
/usr/local/zfs/bin/zed
/usr/local/zfs/bin/zfs

Otherwise, running the LaunchDaemon will throw a 255 error.
