Before we start, let’s download a dmg file from the public domain.

How To Convert DMG Files To ISO Files On Mac

Method 1: Using the Mac terminal

1. Open a terminal window from Finder > Applications > Utilities > Terminal.

2. Assuming that you have a disk image called apple.dmg in the current directory, type

hdiutil convert apple.dmg -format UDTO -o apple.iso

These are instructions on how to convert a DMG image file to an ISO image file using Mac OS X Terminal. You may want to do this if you need to burn a DMG image using a Windows or Linux operating. Tips: After downloading macOS Catalina.dmg file, it is time to make a macOS bootable USB from it. For this purpose, you can give a try on UUByte DMG Editor, one of the most popular software to create a Catalina USB installer on both Windows PC and Mac.

3. This will actually create a file called image.iso.cdr in the current directory (even though we asked for the output to be image.iso). This file can be safely renamed to image.iso, copied to a Windows server or machine, and burned with your CD/DVD burner of choice.

Generally, the command hdiutil can be used this way:

hdiutil convert /path/to/filename.dmg -format UDTO -o /path/to/savefile.iso

Method 2: Using DMGConverter (freeware)

How To Convert DMG Files To ISO Files On Windows

This is for Windows users who might have downloaded a dmg file and wondering how to extract the content, or not even knowing how and what to do with the dmg file. I’ve been there at a certain stage. the sharewares mentioned are fully functional and allows you to use the “convert dmg to iso” function even when it’s not registered yet.

Method 1: Using MagicISO (shareware)

1. Download MagicISO, install and run program.

2. Click to open dmg file.

3. Click to open “Properties” dialogs.

4. Uncheck Apple HFS and Apple HFS+

5. Check “ISO 9660” “Joliet” “UDF”

6. Click OK

7. Click to save as to iso image, or click to burn to CD/DVD without saving.

Method 2: Using UltraISO (shareware)

UltraISO basically does the same thing, but it can save you time from doing step 3 to 6 compared to method 1.

Alternative Solutions: dmg2iso (freeware) and isobuster (shareware)

I’ve heard and read that some people had been able to convert dmg files into iso files using dmg2iso (freeware). I’ve tried dmg2iso, converted my dmg file to iso without problem, but the converted iso file is corrupted and can’t be open by any tools (Daemon Tools, Alcohol, MagicISO, UltraISO and ISOBuster) that I’ve tested. It might work for you, but no guarantees.

ISOBuster is pretty similar to MagicISO and UltraISO. But too bad that the function to “convert dmg to iso” is restricted and won’t be functional until you buy the software.
