    1) Shut off the Mac
    2) Turn it back on
    3) Immediately hold CMD + R after pressing the power button
    4) Should boot into OS X/macOS Utilities
    5) Open Disk Utility
    6) Format Macintosh HD (the bottom of the two listed)
    7) If it won't format or the disk is greyed out, right-click it, select Unlock, and enter the current user password
    8) Ensure the disk is formatted as MacOS Extended (Journaled)
    9) Close Disk Utility and select Reinstall OS X/Reinstall macOS
    10) Sign in with Apple ID if prompted & it'll reinstall a fresh copy of the OS.
