I run HA on a VM (VirtualBox), normally works well but I find that when I run the update of the OS to 10.3, the VM ends up going back to 10.2 after a full reboot say a week after the update. Not sure why it keeps doing this but I have installed 10.3 over 6 times now.
The system clearly says it is 10.3 when it restarted after the update but over time it will end up back at 10.2
Anyone else seeing this?
