How to Convert macOS Mojave Dmg to Iso

Are you trying to mount an ISO image on your Mac running macOS Mojave, but failing? You're not alone. Many users have reported struggling with mounting ISO images on their Macs since the release of Mojave.

In this article, we'll explore the common issues and solutions for converting a dmg file to iso and mounting it on your Mac.

The Problem: No Mountable File Systems

If you've tried using hdiutil attach or hdiutil convert to mount an ISO image on your Mac, you may have encountered the 'no mountable file systems' error. This can be frustrating, especially if you're trying to install a new operating system on a USB drive.

The Solution: Convert Dmg to Iso

One solution is to use the `hdiutil` command-line utility to convert the dmg file to an iso image. Here's how:

1. Open your terminal and navigate to the directory where your dmg file is located.

2. Use the following command to convert the dmg file to an iso image: `hdiutil convert -format UDTO -o debian-8.5.0-amd64-CD-1.iso /path/to/debian-8.5.0-amd64-CD-1.dmg`

3. Once the conversion is complete, you can mount the resulting iso image using the `hdiutil attach` command: `hdiutil attach -nomount debian-8.5.0-amd64-CD-1.iso`

Alternative Method: Use Disk Utility

Another method for mounting an ISO image on your Mac is to use Disk Utility. Here's how:

1. Open Disk Utility, which can be found in the Applications/Utilities folder.

2. Select the USB drive you want to install the operating system onto from the list of available devices.

3. Click the 'Erase' button and select the 'Quick Erase' option.

4. Insert your ISO image into the terminal and use the following command to mount it: `hdiutil attach -nomount /path/to/debian-8.5.0-amd64-CD-1.iso`

Additional Tips

If you're still having trouble mounting your ISO image, there are a few additional things you can try:

* Make sure that your USB drive is formatted correctly and has enough free space to accommodate the operating system.

* Try using a different USB drive or a different computer to see if the issue persists.

* Check the checksum of your ISO image to ensure it's not corrupt.

Converting a dmg file to iso and mounting it on your Mac can be a bit tricky, but with these tips, you should be able to get your operating system installed onto your USB drive. Remember to use the `hdiutil` command-line utility or Disk Utility to convert and mount your ISO image, and don't hesitate to try alternative methods if one doesn't work for you.
