Steps to install macOS Mojave on External Drive

Step 1: Things You Need

  • A Mac computer/Macbook or access to Hackintosh PC
  • TheEFI folder with right config.plist file
  • Patience (sometimes a lot)

Before You Begin

Make sure the external hard drive or SSD does not contain any data as we will be formatting it. If it contains any data, backup it. The same goes for the USB 3.0 8GB stick.

Step 2: Prepare macOS Mojave Installer

  1. Open App store on a Mac or Hackintosh and download Mojave Installer (It’s Free)
  2. Open Disk Utility and connect the USB 3.0 8GB flash drive
  3. Select it and click Erase
  4. Enter a name, eg. MojaveInstaller and choose macOS extended Journaled. Click ‘Erase
  5. Now connect your external hard drive or enclosed M.2 or SATA SSD and click ‘Erase
  6. Enter a name, eg. Mojave HD or Mojave SSD (if using SSD). Choose APFS from the format and click ‘Erase
  7. Now close Disk utility and Open Terminal app
  8. Type following command assuming your USB 3.0 8GB thumb drive name is MojaveInstaller. Replace MojaveInstaller if you have given a different name to your USB stick
    sudo /Applications/Install\ macOS\ --volume /Volumes/MojaveInstaller
  9. After entering the command, press Enter/Return and wait for it to finish
  10. In the Terminal Window, type diskutil list and note down the disk no. of your USB 3.0 *GB Flash Drive and your connected external hard drive or SSD
  11. Then download the EFI mounter app and double-click to open it
  12. Enter the password and double-click the drive number that you saw in the Terminal against your Thumb drive volume
  13. Open Finder and click ‘EFI’ partition
  14. Paste this EFI folder inside the partition.
    Important: The EFI folder we shared works for Dell 7560/7460 and a few other laptops powered by Sky Lake, Kaby Lake, and Coffee Lake i5 and i7 processors. However, you can always edit the EFI folder’s config.plist file according to your system hardware. To know how to edit the config.plist file as per your system hardware, visit this link
  15. Once EFI folder with edited config.plist is pasted in the ‘EFI’ partition of your USB flash drive, eject the partition
  16. Make sure your external hard drive or SSD that we formatted earlier is connected to the system; Once again, double-click EFI Mounter app to run it and enter the password when prompted.
  17. Now choose the drive number that was shown against your external hard drive or SSD in the Terminal command that you entered in step no. 10
  18. Open the Finder and click EFI. Paste the EFI folder here
  19. Now that you have prepared the installer and installation drive, go to your PC or Laptop where you will be running macOS Mojave and connect both drives
