MacBook Pro – How to Erase Linux and Reinstall macOS

macunixusb

I currently am running Kali Linux on my laptop. Currently I need to sell my laptop for some extra cash. I am looking to reinstall Mac OS, so it can be ready for sale. Keeping my current files is not an issue as they have backed up elsewhere.
I have looked up some options but do not know what one would be best.

bootable usb?
mac os disk install?

Thanks

Follow these instructions to erase and reinstall macOS:

Start up from macOS Recovery

  1. macOS Recovery installs different versions of macOS depending on the key combination you use while starting up. Turn on or restart your Mac, then immediately hold down one of these combinations: enter image description here

Erase your startup disk

If you need to erase your startup disk, follow these steps:

  1. Select Disk Utility from the utilities window of macOS Recovery, then click Continue.
  2. Select your device or volume in the sidebar of Disk Utility.
  3. Click the Erase button or tab.
  4. Complete these fields:
    • Name: Enter a name for your disk, such as "Macintosh HD".
    • Format: Choose Mac OS Extended (Journaled) or APFS.
    • Scheme (if available): Choose GUID Partition Map.
  5. Click Erase to begin erasing your disk.

Install macOS

  1. Choose Reinstall macOS (or Reinstall OS X) from the utilities window.
  2. Click Continue, then follow the onscreen instructions. You'll be asked to select your disk. If you don't see it, click Show All Disks.
  3. Click Install. Your Mac restarts after installation is complete.

If you erased your disk before installing, or you installed on an external drive or other new disk, your Mac restarts to a setup assistant.

  • If you're keeping your Mac, complete the setup assistant with your own information.
  • If you're selling or giving away your Mac, press Command-Q to quit the setup assistant without completing the setup steps. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
