Install Mac Os Mojave From Usb

HoRNDIS is now maintained by Mikhail Iakhiaev, and this page is in a state of transition – keep your eyes peeled for updates soon ...

HoRNDIS (pronounce: “horrendous”) is a driver for Mac OS X that allows you to use your Android phone's native USB tethering mode to get Internet access. It is known to work with Mac OS X versions 10.6.8 (Snow Leopard) through 10.14 (Mojave – see notes below), and has been tested on a wide variety of phones. Although you should be careful with all drivers that you install on your computer, HoRNDIS has been tested at least well enough for the author (and many others) to run full time on their own personal computers.

HoRNDIS is implemented as a kext, rather than as a user-space program that opens a TAP or TUN device; this means that it does not conflict with other TAP/TUN kexts that you might have installed (like OpenVPN, Tunnelblick, or Cisco VPN). The driver implements Microsoft's proprietary RNDIS protocol, which is the only protocol supported natively by Android devices; although Linux and Windows users have enjoyed native RNDIS drivers for years, Mac OS X supports only CDC Ethernet devices out of the box.¹⁾

The chief advantage of HoRNDIS over other tethering solutions is that it uses the a first-class supported feature in the phone's firmware. Other solutions either take over the phone's Wi-Fi stack without the Android operating system's knowledge, or create an emulation IP stack in userspace on the phone; in many cases, the built-in USB tethering support can be more stable, more reliable, and faster.²⁾

Therefore there are very few documentations regarding clean installation for Mac OS relative to Windows Reinstallation. In this tutorial, I would try to cover up as much detail I could to help you Reinstall a Clean Mac OS on to your Macbook or iMac. I recommend you to use 16GB or higher USB drive.

Supported version: 0.6.7

While you don't need a fresh install of macOS to use OpenCore, some users prefer having a fresh slate with their boot manager upgrades.

To start we'll want to grab ourselves a copy of macOS. You can skip this and head to formatting the USB if you're just making a bootable OpenCore stick and not an installer. For everyone else, you can either download macOS from the App Store or with Munki's script.

# Downloading macOS: Modern OS

This method allows you to download macOS 10.13 and newer, for 10.12 and older see Downloading macOS: Legacy OS

From a macOS machine that meets the requirements of the OS version you want to install, go directly to the App Store and download the desired OS release and continue to Setting up the installer.

For machines that need a specific OS release or can't download from the App Store, you can use the Munki's InstallInstallMacOS utility.

In order to run it, just copy and paste the below command in a terminal window:

As you can see, we get a nice list of macOS installers. If you need a particular versions of macOS, you can select it by typing the number next to it. For this example we'll choose 10:

macOS 11, Big Sur Note: As this OS is quite new, there's still some issues with certain systems to resolve. For more information, see here: OpenCore and macOS 11: Big Sur
- For first time users, we recommend macOS 10.15, Catalina
Nvidia GPU Note: Reminder to verify whether your hardware support newer OSes, see Hardware Limitations

This is going to take a while as we're downloading the entire 8GB+ macOS installer, so it's highly recommended to read the rest of the guide while you wait.

Once finished, you'll find in your ~/macOS-Installer/ folder a DMG containing the macOS Installer, called Install_macOS_11.1-20C69.dmg for example. Mount it and you'll find the installer application.

Note: We recommend to move the Install macOS.app into the /Applications folder, as we'll be executing commands from there.
Note 2: Running Cmd+Shift+G in Finder will allow you to easily jump to ~/macOS-installer

From here, jump to Setting up the installer to finish your work.

Install Macos Mojave From Bootable Usb

# Downloading macOS: Legacy OS

This method allows you to download much older versions of OS X, currently supporting all Intel versions of OS X(10.4 to current)
- Legacy macOS: Offline method
  - 10.10-10.12 Supported
- Legacy macOS: Online method(10.7-10.15 Supported)
  - 10.7-11 Supported
- Legacy macOS: Disk Images
  - 10.4-10.6 Supported

# Setting up the installer

Now we'll be formatting the USB to prep for both the macOS installer and OpenCore. We'll want to use macOS Extended (HFS+) with a GUID partition map. This will create two partitions: the main MyVolume and a second called EFI which is used as a boot partition where your firmware will check for boot files.

Note: By default, Disk Utility only shows partitions – press Cmd/Win+2 to show all devices (alternatively you can press the View button)
Note 2: Users following 'Legacy macOS: Online method' section can skip to Setting up OpenCore's EFI environment

Next run the createinstallmedia command provided by Apple(opens new window). Note that the command is made for USB's formatted with the name MyVolume:

This will take some time so you may want to grab a coffee or continue reading the guide (to be fair you really shouldn't be following this guide step by step without reading the whole thing first).

You can also replace the createinstallmedia path with that of where your installer's located (same idea with the drive name).

# Legacy Setup

For systems not supporting UEFI boot, see below:

Setting up Legacy Boot

To start, you need the following:

BootInstall_IA32.tool or BootInstall_X64.tool
- This can be found in OpenCorePkg under /Utilties/LegacyBoot/
Install USB(Created above)

Within your OpenCore build folder, navigate to Utilities/LegacyBoot. Here you'll find a file called BootInstall_ARCH.tool. What this does is install DuetPkg to your desired drive.

Now run this tool in terminal with sudo(This tool will likely fail otherwise):

This will give you a list of available disks, choose yours and you will be prompted to write a new MBR. Choose yes[y] and you'll be finished.

This will provide you with an EFI partition with either a bootia32 or bootx64 file

# Setting up OpenCore's EFI environment

Setting up OpenCore's EFI environment is simple – all you need to do is mount our EFI system partition. This is automatically made when we format with GUID but is unmounted by default, this is where our friend MountEFI(opens new window) comes in:

You'll notice that once we open the EFI partition, it's empty. This is where the fun begins.
