TransMac - Make DMG File Bootable USB on Windows. This is a fairly robust application for creating bootable USB on Windows from a DMG file. However, there's a preparatory step to be executed before you can create the bootable USB drive.

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.

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.

Step 1. Now Attach the USB Flash Drive to the Computer.

Step 2. Run TransMac as Administrator, if it is not given the full privileges it can’t create bootable USB for macOS Mojave.

Step 3. Right click on the USB and select format disk for mac.

Step 4. Once the disk is formatted for Mac, again right click and select Restore with Disk Image.

Step 5. Now the TransMac will warn that all files will be overwritten, so you have to click on the Yes and move to the next step.

Step 6. Now locate the macOS Mojave dmg file by clicking on the three dots.

Step 7. Once again it will warn you, that all the files will be overwritten, so you have to click yes.

Step 8. Have patients until the process of copying files should be complete, once it is done. Attach it to a computer and start installing macOS Mojave on PC.

Please keep in mind that the TransMac is only campable of creating a UEFI partition not legacy. If you are looing to create a legacy bootable USB Flash Drive you have to try using the Unibeast on Virtual Machine to create bootable USB.
