Part 1. Prepare an external drive

You need an external drive of at least 14 GB. Although the macOS installer is around 12GB, you’ll still need some extra space to store your data.

  2. Open Disk Utility using Spotlight.

  3. Select your drive in the sidebar and click the “Clean” button at the top of the window.
