- 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
- Open App store on a Mac or Hackintosh and download Mojave Installer (It’s Free)
- Open Disk Utility and connect the USB 3.0 8GB flash drive

- Now connect your external hard drive or enclosed M.2 or SATA SSD and click ‘Erase‘
- Enter a name, eg. Mojave HD or Mojave SSD (if using SSD). Choose APFS from the format and click ‘Erase‘
- Now close Disk utility and Open Terminal app
- 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
- After entering the command, press Enter/Return and wait for it to finish
- 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
- Then download the EFI mounter app and double-click to open it
- Enter the password and double-click the drive number that you saw in the Terminal against your Thumb drive volume
- Open Finder and click ‘EFI’ partition
- 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 - Once EFI folder with edited config.plist is pasted in the ‘EFI’ partition of your USB flash drive, eject the partition
- 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.
- 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
- Open the Finder and click EFI. Paste the EFI folder here
- 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

- After installation is done, the system will reboot and again you need to press boot options key to choose your external drive as boot drive where you just installed macOS Mojave
Tip: You can set your external hard drive or SSD as default drive from BIOS settings. refer to your user manual or manufacturers website to know how to set boot priority order. You can also visit this link to know how it’s done. - Now setup your macOS Mojave OS and choose between light or dark mode

Disk Utility User Guide
Disk Utility on Mac supports several file system formats:
How To Format An External Drive
Apple File System (APFS): The file system used by macOS 10.13 or later.
Mac OS Extended: The file system used by macOS 10.12 or earlier.
MS-DOS (FAT) and ExFAT: File systems that are compatible with Windows.
Apple File System (APFS)
Apple File System (APFS), the default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. While APFS is optimized for the Flash/SSD storage used in recent Mac computers, it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. macOS 10.13 or later supports APFS for both bootable and data volumes.
APFS allocates disk space within a container on demand. The disk’s free space is shared and can be allocated to any of the individual volumes in the container as needed. If desired, you can specify reserve and quota sizes for each volume. Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all the volumes in the container.
Choose one of the following APFS formats for Mac computers using macOS 10.13 or later.
APFS: Uses the APFS format.
APFS (Encrypted): Uses the APFS format and encrypts the volume.
APFS (Case-sensitive): Uses the APFS format and is case-sensitive to file and folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.
APFS (Case-sensitive, Encrypted): Uses the APFS format, is case-sensitive to file and folder names, and encrypts the volume. For example, folders named “Homework” and “HOMEWORK” are two different folders.
You can easily add or delete volumes in APFS containers. Each volume within an APFS container can have its own APFS format—APFS, APFS (Encrypted), APFS (Case-sensitive), or APFS (Case-sensitive, Encrypted).
