Why not give the actual version 2.1.0 a try? I'm using it on an Intel-based Mac with 11.5.2 on it without problems.

Importing your pool should work out-of-the-box. You only have to pay attention when you want to use it on another machine that uses an older ZFS version. In that case you should avoid upgrading the pool, but apart from that you can just use it.

thanks for that! i will try and give you report! regards w

ok i installed zfs 2.1.0 for big sur arm and now cannot import my pool. last export was on my old mac with catalina and the old zfs! what can i do?

if have installed zfs 2.1.0 and restarted the imac, but:

% zfs status
The ZFS modules are not loaded.
Try running '/sbin/kextload zfs.kext' as root to load them.??

what did i do wrong?

Did you approve the kexts in System Preferences > Security & Privacy > General? It should prompt you to do that during the install but I think some people have had trouble or have had to approve them twice.

Edit: See the section here called Explain the Kext-Loading Process to Users. It looks like there are some extra steps for ARM Macs.

i tried again to install zfs 2.1.0 on my new arm mac with big sur 11.5.2 but it still will not install correctly, i reduced the security startup for the kernel extensions and allowed security for lundman, still is not installed???
need help
thanks

ah! i have forgotten to make a newstart! and then import the old pool with "-f" and then upgraded and then everything is ok and works! now i have access to my pool
thanks for helping!
