When you see the utilities window, you have started up from macOS Recovery.

3. Install macOS
When you're ready to reinstall macOS, choose Reinstall macOS from the Utilities window. Then click Continue and follow the onscreen instructions. You will be asked to choose a disk on which to install.
- If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
- If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
- If the installer is for a different version of macOS than you expected, learn about macOS Recovery exceptions.
- If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
If your Mac restarts to a setup assistant, but you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.

Did you just buy your first Mac mini? Wondering how the heck this thing even works? It's easier than you think. It's like a tiny stand-alone computer that you get to bring your own monitor and mouse to. Here's how to set it up.
What you'll need
The new Mac mini is Apple's version of a barebones computer. The entry model starts at $799 and only comes with the Mac mini, a power cable, and documentation. You'll need to provide your own monitor, keyboard, and mouse or trackpad. Since the new Mac mini has a number of I/O ports, your choices of monitor connectivity can be in the form of a Thunderbolt 3 connector or an HDMI connector. Whether you use your 5K Thunderbolt Display or your spare 1080p television with HDMI, the new Mac mini will be good to go. The new Mac mini also has two USB 3.1 ports so if you have older wired keyboards or mice, you'll be all set as well.
Setting up the hardware
- Ensure that your desk or table has access to two power plugs, one for your monitor and one for your new Mac mini. Plug them in.
- Attach your monitor cable to both the monitor and the new Mac mini.
- If you have a new wireless Apple keyboard and trackpad, you'll need to attach them via a Lightning to USB cable so that they both charge and pair via Bluetooth to the new Mac mini. These can be removed once pairing and charging are complete.
- After you've verified all cables are properly connected you can press the power button. You'll know the new Mac mini is powered on with the illumination of a silver LED on the front.
