I recently installed the macOS Mojave developer beta on my MacBook Pro. Everything worked fine and I could start both macOS and Windows.
Today, when updating to the beta 2, however, the installation got stuck at 16 minutes remaining for over an hour at which point I force restarted the computer.
macOS still boots fine. Also Windows still appears as an option when I hold down the ⌥ (Option) key on boot. However, when I click on it macOS starts instead.
