At work and was reimaging/downloading OS on iMac's for an event. One machine was midway through process and was accidentally unplugged. Now machine won't boot back up and I am unsure how to proceed
iMac Pro
Reboot the iMac in Recovery mode and reinstall the (an) OS.
You can probably use Command-R startup keys, but if that fails, try Option-Command-R or Shift-Option-Command-R.
