Jul 08, 2018 This guide will walk you through creating a bootable flash drive installer for macOS Mojave which is started by first formatting the a USB flash drive and transferring the Mojave Installer over and then creating the boot partition necessary to run the Mojave Installer on a hackintosh on a non-Mac PC. Aug 02, 2018 A 16 GB USB Flash Drive-Download macOS Mojave Dmg File. Well, if you are using a Mac Operating system, it is obvious that you can download the macOS 10.14 Mojave from the App Store. But if you are not using a mac operating system, also you want to create a Bootable macOS Mojave USB Installer on Windows, your first priority is to download the.
Apple hasn’t shipped operating systems on physical media in almost a decade, but there are still good reasons to want a reliable old USB stick for macOS Mojave. Luckily, it's not hard to make one—either with a handy graphical user interface or some light Terminal use. Here's what you need to get started.
- A Mac that you have administrator access to. We've created Mojave USB stick from both High Sierra and Mojave, but your experience with other versions may vary.
- An 8GB or larger USB flash drive or an 8GB or larger partition on some other kind of external drive. A USB 3.0 drive will make things significantly faster, but an older USB 2.0 drive will work in a pinch.
- The macOS 10.14 Mojave installer from the Mac App Store in your Applications folder. The installer will delete itself when you install the operating system, but it can be re-downloaded if necessary.
- If you want a GUI, take a look at Ben Slaney's Install Disk Creator from MacDaddy. There are other apps out there that do this, but this one is quick and simple.
If you want to use this USB installer with newer Macs as they are released, you'll want to periodically re-download new Mojave installers and make new install drives periodically. Apple rolls support for newer hardware into new macOS point releases as they come out, so this will help keep your install drive as universal and versatile as possible.
There's also one new consideration for newer Macs with Apple's T2 controller chip—as of this writing, the iMac Pro and both 2018 MacBook Pros. Among this chip's many security features is one that disallows booting from external drives by default. To re-enable this feature, hold down Command-R while your Mac reboots to go into Recovery Mode, and use the Startup Security Utility to 'allow booting from external media.' If you're trying to install an older version of macOS, you may also need to go from Full Security to Medium Security to enable booting, but if you're just trying to install the current version of macOS, the Full Security option should be just fine.
The easy way
Once you've obtained all of the necessary materials, connect the USB drive to your Mac and launch the Install Disk Creator. This app is basically just a GUI wrapper for the terminal command, so it should be possible to make install disks for versions of macOS going all the way back to Lion. In any case, it will work just fine for our purposes.
Install Disk Creator will automatically detect macOS installers on your drive and suggest one for you, displaying its icon along with its path. You can navigate to a different one if you want, and you can also pick from among all the storage devices and volumes currently connected to your Mac through the drop-down menu at the top of the window. Once you're ready to go, click 'Create Installer' and wait. A progress bar across the bottom of the app will tell you how far you have to go, and a pop-up notification will let you know when the process is done. This should only take a few minutes on a USB 3.0 flash drive in a modern Mac, though using USB 2.0 or other interfaces will slow things down.
The only slightly less-easy way
The Install Disk Creator is just a wrapper for the terminal command to create macOS install disks, so if you’re comfortable formatting your USB drive yourself and opening a Terminal window, it’s almost as easy to do it this way. Assuming that you have the macOS Mojave installer in your Applications folder and you have a Mac OS Extended (Journaled)-formatted USB drive (which is to say, HFS+ and notAPFS) named 'Untitled' mounted on the system, you can create a Mojave install drive using the following command.
sudo '/Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia' --volume /Volumes/Untitled --nointeraction --downloadassets
The command will erase the disk and copy the install files over. Give it some time, and your volume will soon be loaded up with not just the macOS installer but also an external recovery partition that may come in handy if your hard drive dies and you're away from an Internet connection. If you’d like to create an install drive for a macOS version other than Mojave, just tweak the paths above to refer to Sierra or High Sierra instead.
Whichever method you use, you should be able to boot from your new USB drive either by changing the default Startup Disk in System Preferences or by holding down the Option key at boot and selecting the drive. Once booted, you'll be able to install or upgrade Mojave as you normally would. You can also use Safari, Disk Utility, or Time Machine from the recovery partition to restore backups or troubleshoot.

DMG file is a compressed file format being used widely on Mac computer. Windows OS doesn't natively support DMG disk image files, so if you need to create a bootable USB drive from a DMG file, mostly for bootable Mac OS X or macOS installation USB, you need a special utility to help you complete the task.
There is also the possibility of converting the file into a format more suitable for Windows, which is the ISO file format for disk images. Considering the above, let's look at different ways to create a bootable drive from a DMG file on a Windows computer.
Part 1: Convert DMG to ISO and Make Bootable USB from ISO
Since Windows doesn't offer native support for DMG files, you can first convert the file to ISO. Why? A lot of easier to find an app for making a bootable USB from ISO file. The easy way to do this is to use Command Prompt. Don't be intimidated by the non-GUI environment even if you don't have any experience. If you follow the steps below, you can convert any DMG file to ISO and then create a bootable USB using the converted file.
Step 1: Open Command Prompt by typing cmd in the Run windows and hitting Enter.
Step 2: In the command interface, go to the directory in which the DMG file is saved. You can do this by using the 'cd' command followed by the file path, then pressing Enter. For example, if your disk image is in D: and Command Prompt is currently in 'C:', then type 'd:' (no quotes) and press Enter. If it is in a subfolder, type 'cd subfolder', and so on.
Step 3: Use the following command to convert the DMG file to ISO:
hdiutil convert /path/sourceimagefile.dmg -format UDTO -o /path/targetmage.iso
Step 4: Once the ISO file has been created, you can use a burning tool to create the bootable USB drive. To do that, continue with this guide.
Cons:
- File damged or broken after conversion.
- Failed booting from burned USB disk.
- May not work with the latest DMG file.
- Complex and take more time.
Part 2: Create Mac OS X Bootable USB Installer from DMG
Androidphonesoft DMG Editor is a powerful software application for Windows that will allow you to manage the non-native DMG format even if you have no experience. The interface is uncluttered, and you can even use the tool to view files, extract them, edit the DMG and even copy it to a disk. The burn function has one of the highest success rates in the industry, which makes this an ideal utility for our purpose.
Created by the talented team of developers at Androidphonesoft, DMG Editor is currently the most intuitive Windows app for handling Apple's disk image format. Each of its functions have been tested on various Windows versions, with different types of DMG files and on different PC brands. This thorough testing means no wasted DVDs or corrupted files. As long as your DMG file is in good shape, you can directly create a bootable disk.
Step 1 Install DMG Editor
Download and install DMG Editor on your Windows PC.
Step 2 Plug in USB Drive
Mac Os Mojave Bootable Iso
Launch the application and click on the 'Burn' section. You will also see other modules such as Edit, Extract and Copy.
Step 3 Start Burning ISO File to USB
Now import the DMG file by clicking the 'Load DMG' button, and click on 'Burn'.
In a few moments, your bootable USB flash drive will be ready for use. Since you haven't done any conversion, you can use this directly on a Mac for program installation, which you cannot do with the first method.
Part 3: Create Bootable USB from DMG in Windows Via PowerISO
Another well-known disk image utility is PowerISO. Apart from being ideal for burning ISO files, it can also burn a DMG file to USB to create a bootable drive. There are some settings that you have to keep in mind when burning with this software, but it's easy to get the hang of it once you do it a couple of times.
Step 1: Download PowerISO and install it in your Windows PC. Launch the app and insert a USB drive into a free USB slot in your computer.
Step 2: You can import the DMG file directly by clicking on ‘Burn' in the toolbar or going to Tools >Burn. In the Burn window, select the DMG file from the Source File section.
Step 3:Now review the settings to select the burn speed. The default will be the maximum your hardware can handle, so you can reduce that. You can also choose to finalize the disk and verify it. Finalizing means you can't save any more files on the drive, but it primarily applies to DVDs and CDs. Choosing ‘Verify' will prompt the software to execute an additional process after the burning is done. Any errors in the bootable USB will show up at that point.
Step 4: Now click on 'Burn' and wait for the progress bar to reach 100%. Your bootable USB is now ready.
Cons:
- Expensive for a single license.
- Higher failure rate for bootable device.
- Ugly user interface.
The Bottom Line:
The second two methods are recommended if you don't have much experience working with DMG files, but DMG Editor will appeal to novices and experts alike. The clean interface and minimal user input means a lower chance of errors while creating the bootable media.
