I updated my Macbook Pro Retina 2014 model to the MacOS Sierra a couple of weeks back. I realized that when I shut down the Laptop or Restart my laptop it takes at least 15 minutes. I recently also update to Beta version 2 but I'm still facing this issue. Has anyone else faced similar issues. Does anyone know if this is a bug in this new OS or if there is anything else I can check to fix this? Any help is greatly appreciated.
