If your Mac suddenly refuses to boot up properly, you might need bootable macOS install USB to make repairs. But how do you create such a disk if all you're left with is a Windows 10 computer? Fortunately, there's a great tool that you can use for free to create bootable macOS media on a USB drive in a Windows 10 environment. This article shows you how to download a macOS DMG file, format a USB drive using a GUID Partition Table, burn the DMG to the drive and boot your Mac from the USB. All the steps except the last one are done on a Windows 10 machine.

Jul 20, 2017  If you’re switching to macOS from Windows, you might be confused about installing software. Sure, there’s the Mac App Store, but not everything is in there. If you look for apps outside the store, you’ll find different kinds of installers: DMG files with apps in them, PKG installers, and simple applications inside ZIP archives.

  • Apr 16, 2019  When you download software for your Mac computer, it usually comes in form of DMG files. These DMG files are actually disk image files supported only on Mac operating system. You can mount them in your Mac computer and read the contents easily. But what if you want to access the contents of these DMG disk images from inside your Windows PC?
  • Jun 18, 2008  Anyways, does anyone know if it is possible to download a DMG file on a Windows machine, move it to a Mac via memory stick, then install the DMG on the Mac? I know that data bits are just bits, but I'm concerned primarily about any Mac/Windows endian issues and Windows doing something 'weird' with the contents of a DMG file.

Part 1: Download macOS or Mac OS X DMG File

The first step is to get the DMG disk image file for the version of macOS that you want. You can get a copy of the latest macOS version from Apple download portal or App Store here. There are also several other direct download sites that offer various versions of Mac OS X in DMG format rather than the standard APP format that runs on Mac. Since you're working in a Windows environment, you need the DMG rather than the APP file.

Part 2: Format USB Drive to GPT

Mostly, the USB drive was formmated to FAT32 in default when being shipped out from the factory. However, FAT32 can be only used for installing OS with legacy BISO, which doesn't work for macOS. So the next step is to format your USB drive in the GPT partition style in order to burn installation files to the desired USB drive. You can do this in Command Prompt as admin. In elevated Command Prompt (Ctrl+Shift+Enter), input the following series of commands followed by Enter after each line:
Diskpart
List disk
Select Disk X (X stands for the USB drive name that appears after the previous command)
Clean
Convert GPT
Create partition primary

Part 3: Create Bootable macOS USB from Windows 10

You have now formatted the partition of USB drive. It's time to download TransMac for Windows. Although this is a premium software, you can use the initial free trial period to create a bootable macOS USB drive on Windows 10. After installing the application, follow the sequence of steps shown below:

Step 1: Right-click the icon and select Run as Administrator from the contextual menu. Choose Run when prompted.

Step 2: Insert your formatted USB drive, and you will be able to see it in the TransMac software on the left panel.

Step 3: Right-click the USB and select Restore with Disk Image in the contextual menu. Click Yes in the warning popup.

Step 4: You will see a window that says Restore Disk Image to Drive. Here, select your DMG file in the dropdown menu and click OK.

Depending on the system configuration, this can take anywhere from a few minutes to a couple of hours. Once the progress bar is at 100%, a bootable USB is ready.

Part 4: Boot macOS Install USB on Mac

Now remove the USB drive and insert it into the Mac computer. To boot from the disk, you need to hold down the option key when you hear the boot chime. This will take you to the Startup Disk Manager, where you should be able to see the USB drive. It might have a different name, but as long as it is bootable, you'll be able to see it there. Once you select it, the computer will boot from the disk and the macOS installation will begin.

Conclusion:

The whole process might look a bit complicated if this is your first time, but just follow the instructions in this article and you should be fine. That being said, you need to be careful when downloading the DMG file and formatting your USB drive. If you don't do these two steps correctly, the output drive from the TransMac software won't be bootable, which means you can't install macOS using it, and you may need to do the whole thing over again.

While macOS Mojave and even macOS Catalina has been out for a while now, but there might be several reasons why macOS High Sierra might be best for you. Now for installing that, you will probably need a macOS High Sierra DMG file we’ve provided with direct links. One of those reasons which might have stopped from the upgrade to macOS Mojave or macOS Catalina is its compatibility. While macOS Catalina and macOS Mojave require some newer Macs to be installed on and prevent other Macs to install macOS High Sierra. While there are some ways to skip that and install macOS Mojave or install macOS Catalina on your unsupported Mac but that’s not always the only option to take.

Another reason which might have stopped you from upgrading or installing macOS Mojave or macOS Catalina is its performance. Though macOS Catalina has all of the macOS Mojave features and a lot more than those features, even new features especially Dark Mode which most loves. Another useful feature that might really help is Stacks, it organizes and turns mess into a clean desktop by putting files and folders into one according to them.

Just like the old proverb which is “Old is gold”, those features and things mightn’t be enough to impress you. I completely understand that, because I did the same when Windows 10 was out, I didn’t upgrade for a quite while. Apart from this, even if you’re compatible for Catalina, installing macOS Catalina might pop up some problems at least like its dropping support for 32-bit apps which many users complain about.
