Oct 24, 2011  1. On your Mac, open up Disk Utility. Click on the USB Drive on the left. On the right pane, go to the Restore tab. Click on the Browse button and locate the.dmg installer for OS X Lion. (ie macosx10711a390.dmg) 4. Once you have it chosen, click and drag your USB Thumbdrive from the left pane to the Destination box.

These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

Download macOS

Find the appropriate download link in the upgrade instructions for each macOS version:

  • macOS Catalina, macOS Mojave, and macOS High Sierra download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation.
    To get the required installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
  • macOS Sierra downloads as a disk image that contains a file named InstallOS.pkg. Open this file and follow the onscreen instructions. It installs an app named Install macOS Sierra into your Applications folder.
  • OS X El Capitan downloads as a disk image that contains a file named InstallMacOSX.pkg. Open this file and follow the onscreen instructions. It installs an app named Install OS X El Capitan into your Applications folder.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.
    Catalina:*
    Mojave:*

    High Sierra:*
    Sierra:
    El Capitan:
  4. Press Return after typing the command.
  5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  6. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
  7. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument, similar to the way this argument is used in the commands for Sierra and El Capitan.

Use the bootable installer

After creating the bootable installer, follow these steps to use it:

  1. Plug the bootable installer into a compatible Mac.
  2. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
    Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it.
  3. Choose your language, if prompted.
  4. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
  5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

Windows and Mac, they both are designed with different companies with a different file system. Because of their File system, it seems to us that we can’t create bootable USB for macOS Mojave on Windows. And the same goes for mac, where we are thinking we can’t create bootable USB for Windows 10 in mac. However, if you have used the Mac operating system, then you know that you can create bootable USB for Windows in mac with terminal and some other applications. But if you have used windows you will find out that you are not even able to create bootable USB for macOS Mojave using CMD or PowerShell. However, if we compare the Terminal and PowerShell, Terminal is built upon the Linux Codes and Infrastructure. but PowerShell is built by mixing all Unix, CMD, Scripts and other kinds of stuff. Jeffery Snover the founder of PowerShell said that anyone can work on PowerShell based on their platform. it means that if you are a Linux user you can use PowerShell, just like you are using the Linux terminal. This way PowerShell seems to be Powerful but yet no one has achieved to create bootable USB for macOS Mojave on Windows. I bet that for programmers it is not a hard thing but they are not interested in that. It is we, the basic users who wish to use a different operating system.

So, enough of talk and let’s dive into creating bootable USB for macOS Mojave on Windows with TransMac, I hope it will be helpful for you.

Required Files:

  • macOS Mojave Dmg File: In order to create bootable USB for macOS Mojave in windows 10, the first thing which is required is the macOS Mojave dmg File. If you have used a mac operating system, then you know that you can’t download macOS Mojave except for app store. I don’t know how, but programmers have decoded that from mac and uploaded the dmg file for windows users. Now windows user can download the macOS Mojave dmg file and they can use it to create bootable USB. And keep one more thing in your mind, if you visit any site download macOS Mojave iSO, then the flash won’t be bootable correctly. Because of those how are providing you the macOS Mojave ISO file, they have simply converted the macOS Mojave dmg file using PowerISO. Converting macOS Mojave dmg file to any other extensions requires a specific set of skills in the coding of an operating system. So, it is so rare that anyone put that much effort. However, I can’t predict if someone changes the macOS Mojave dmg to iSO in the future.
  • 16 GB USB Flash: The macOS Mojave dmg file size is actually is 6.7 GB and at least it requires 8 GB of storage to extract the files. But since many users are facing errors, I would you recommend you to use a 16 GB USB Flash. And please make sure that the USB must be 3.0 because with USB 3.0 it takes 50 minutes to create bootable USB and I wonder How much time it would take for USB 2.0 to Create bootable USB.
  • Transmac: TransMac is a software which is specifically built for windows users to mount, format, edit and create bootable for macOS. However there is also alternative software to TransMac but they are working best for Hackintosh file system (HFS), but since macOS high Sierra and macOS Mojave have Apple File system (APS), they can’t support it. Another thing which you must know about the TransMac, that TransMac is not free forever, it only provides you 15 days of trial. But After that, you have to purchase it.

Before creating bootable USB for macOS Mojave in windows 10 using TransMac, you have to download and Install TransMac. Installing TransMac is so simple and it does not require too much attention but in case if you don’t know How to Install. Follow the below procedures:

  • Double click on the setup to launch the installation wizard.
  • Click next, next, next, and next.
  • Now click on the Install to copy the TransMac Files to your root drive.
  • When the Installation is done, click Finish.
