Convert DMG to ISO using this tool! 21.07.2018
If you plan to create an USB stick for your Macintosh or Hackintosh from something that is not macOS, you will get a tool called TransMac recommended by most tutorials. But honestly, it is no fun as it has a long counter running at startup when not activated, further it is actually a trial version and a license costs a ton of money.
Instead, i found something else, it’s a little Java tool called DMGExtractor, which is not only free, it is even OpenSource software. Even tho it is quite old, it works perfectly fine.
With just a few steps it will convert your DMG to an ISO file which you then can smash to your USB using Rufus for example (when on Windows).
