Clean Install High Sierra on APFS-formatted main HD

Installation Steps

  1. From 10.11 or 10.12 systems, format an external hard drive with at least 500gb with "Mac Os Extended Journaled".
  2. Download High Sierra Beta and install it in the external hard drive.
  3. When the system reboots and finishes installation, it will boot from the external HD. Go to Preferences and change Startup Disk to be main HD.
  4. Reboot and press Option key when the computer makes a beep and select external HD to boot from it.
  5. Once booted again into external HD, format main HD to be APFS.
