Dud?
Running MacOS Sierra Beta 7
1. Downloaded MacOS Sierra GM redeeming the code
2. Made a backup
3. Cloned the drive
4. Restarted and switched to the cloned drive
5. Initiated install on the cloned drive. Started OK and took few minutes to the first reset point
6. ON reset, it seemed to start the install but then broke off after a minute (the bar at around 5%, no messages) or so and then started up as Beta 7 (build code didn't change)
Is running fine, as if nothing happened.
Any ides here?
P.S. Tried again, and behavior is the same as described above...
