TransMac : Access and Create Mac Disk Images (DMG) in Windows

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? You can use an old version of Aladdin Stuffit Expander (if you can still find it online) to extract the contents of DMG files. But if you want to both read the contents of an existing DMG file and create new disk images then you can try TransMac.

Access contents of DMG disk images
TransMac makes it very easy to access the contents of any DMG disk image. For this, you can launch TransMac and click on the “Open Disk Image” icon in the toolbar. After this you can select the DMG disk image file from your hard drive and it will be shown as mounted in the TransMac interface. You can now explore its contents. If you want to extract any files from the mounted DMG file, then you can right-click on those files/folders, select “Copy To” and then choose a destination folder.


Create new DMG disk images and add new content
If you want to create a new disk image, then you can click on the “New Disk Image” icon in the toolbar. It will show a small window asking you to give the disk name (volume label) and the disk size. Choose a disk size wisely because it cannot be altered later.


After the new disk image has been created, it will ask you if you want to mount the new image. You can choose yes to load it in TransMac. Now you can open the new disk image’s root folder and can create new folders and copy/paste files from your hard drive in Windows. All the changes to the disk contents are saved automatically.


TransMac is a useful software for those who do not always have access to their Mac computers. It can be used to access, modify and create DMG disk images in Windows without any special drivers. It creates the DMG images with Apple HFS+ file system.
