Hi there,


  1. Select "View" in the toolbar > "Show All Devices".
  2. Select your main hard drive. This will either be "APPLE SSD...", "APPLE HDD...", or "Fusion Drive".
  3. Click Erase, and input the following exactly: (If you cannot select erase on the main hard drive, erase the "Container".)
  4. Name: Macintosh HD
  5. Format: APFS
  6. Scheme: GUID Partition Map (if shown)
  7. Click Erase
  8. Quit Disk Utility
  9. Go to the reinstall macOS app.
  10. Follow the prompts, and install on Macintosh HD.


Cheers,


Jack
