#but for MACOS, this on Sonoma:
#Add hard disk to VM or bare metal. In my case Proxmox VM added hard disk with bus device VIRTIO and RAW file format.

#Boot into MacOS
# open Terminal
#Install Brew per https://brew.sh/
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
# needs like 10 GB of free space.....

#if you need to add 10GB of hard disk space on VM macOS
#shutdown Macos
# in Proxmox under correct VM, Hardware, Disk Action, + Resize, enter 10GB
# boot into VM Macos
#open Terminal
diskutil repairdisk disk0
diskutil apfs resizeContainer disk1 0
# now you should have extra 10GB

#if you ran out of space in previous install try again
#Install Brew per https://brew.sh/
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

#after succesfull brew install, per https://formulae.brew.sh/cask/openzfs#default
brew install --cask openzfs

diskutil list
#identify disk number for added new zfs disk, [ in my case disk0 ]

sudo zpool create -f -o ashift=12 -O casesensitivity=insensitive -O normalization=formD tank disk0

#pool already imported automatically when created, go straight to
zpool status
sudo zfs create tank/data
zfs list

#enable SSH key login to ZFS server you want to send snapshot to, with no password
#test ssh to server that it works with no password

sudo zfs snapshot tank/data@v0

zfs list -t snapshot

sudo zfs send tank/data@v0 | ssh root@192.168.X.Y zfs receive proxmoxpool/sonoma

sudo zfs snapshot tank/data@v1

sudo zfs send -i tank/data@v0 tank/data@v1| ssh root@192.168.X.Y zfs receive -Fv proxmoxpool/sonoma

#works!

The reason for manual ZFS send is lack of Sanoid / Syncoid fully functional with Brew install or other ready MacOS package.

If you want to try, there is a pearl script for Sanoid / Syncoid for MacOS

and

# I have not tested it, lack of Pearl skills.
