Howdy. I'm getting errors with this new pkg on my freshly upgraded MacPro 2013 Catalina system. I then installed the previously released stable 1.9.2 and was able to mount my pool and read/write to it. Unmounting and remounting failed and open reboot, got the same type of error. Anyone see the same? Hints?
Thank you all for shedding light on the issue. I was able to work around the Catalina kext bug by using the uninstall script, manually deleting the spl.kext and zfs.kext files in /Library/Extensions/ rebooting and then installing the Catalina Supplemental Update which fortuitously became available during my time debugging this. I installed ZFS after the update and I was able to verify I had the right kext versions after that.
I see there's a new ZFS build and if I understand the linked analysis, there's not an easy workaround. Does anyone know if this is addressed in the upcoming Catalina 10.15.1 update? The third developer beta was released today.
