I updated my iMac (Late 2015 i5 3.2Ghz 5K) to the latest PB 10. But unlike every other PB it is stuck installing the new beta. It has been like this for over an hour. See image. Is my only option to recover from Time Machine??

In the future, I would just let it sit for a day or so and see what happens. I updated my macbook air 2017 and it did the same thing, i just let it sit for 2hrs and eventually things moved along...
