I have some information about converting your DMG file. Since DMG files are MacOS disk image files, you won't be able to open them directly in Windows. You'll want to check for a DMG converter.
You can check on the website for a third-party application or go to this link: https://desktop.apps.com/home.
In case you need help with other tasks in QBDT, browse this link here to go to our general topics with articles.
Keep me posted if you still have questions or concerns with your file. I'll be around for you. Take care and have a great day ahead.
