Burn Dmg To Disk Mac Pro

  1. In the Disk Utility app on your Mac, choose File > New Image > Blank Image.

  2. Enter a filename for the disk image, add tags if necessary, then choose where to save it.

    This is the name that appears in the Finder, where you save the disk image file before opening it.

  3. In the Name field, enter the name for the disk image.

    This is the name that appears on your desktop and in the Finder sidebar, after you open the disk image.

  4. In the Size field, enter a size for the disk image.

  5. Click the Format pop-up menu, then choose the format for the disk:

    • If the disk image will be used with a Mac that has a solid state drive (SSD) and uses macOS 10.13 or later, choose APFS or APFS (Case-sensitive).

    • If the disk image will be used with a Mac with macOS 10.12 or earlier, choose Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled).

    • If the disk image will be used with a Mac or Windows computer and is 32 GB or less, choose MS-DOS (FAT); if it’s over 32 GB, choose ExFAT.

  6. To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.

  7. Click the Partitions pop-up menu, then choose a partition layout.

  8. Click the Image Format pop-up menu, then choose an option:

    • Sparse bundle disk image: Same as a sparse disk image (below), but the directory data for the image is stored differently. Uses the .sparsebundle file extension.

    • Sparse disk image: Creates an expandable file that shrinks and grows as needed. No additional space is used. Uses the .sparseimage file extension.

    • Read/write disk image: Allows you to add files to the disk image after it’s created. Uses the .dmg file extension.

    • DVD/CD master: Changes the size of the image to 177 MB (CD 8 cm). Uses the .cdr file extension.

  9. Click Save, then click Done.

    Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

  10. In the Finder, copy your files to the mounted disk image, then eject it.

  11. Restore the disk image to a disk.

    For more information about disk image types, see the manual (man) page for hdiutil.

Create a disk image from a disk or connected device

You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. You can then restore that disk image to another volume.

  1. In the Disk Utility app on your Mac, select a disk, volume, or connected device in the sidebar.

  2. Choose File > New Image, then choose “Image from [device name].”

  3. Enter a filename for the disk image, add tags if necessary, then choose where to save it.

    This is the name that appears in the Finder, where you save the disk image file before opening it.

  4. Click the Format pop-up menu, then choose an option:

    • Read-only: Osx 10.7 dmg tpb. The disk image can’t be written to, and is quicker to create and open.

    • Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.

    • Read/write: Allows you to add files to the disk image after it’s created.

    • DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.

  5. To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.

  6. Click Save, then click Done.

    Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

Important: Don’t create a disk image of a disk that you believe to be failing or that contains corrupted information. The disk image may not serve as a reliable backup.

For technical information about creating a restore disk image, see the Apple Software Restore (ASR) manual (man) page.

Create a disk image from a folder or connected device

You can create a disk image that contains the contents of a folder or connected device, such as a USB device. This method doesn’t copy a device’s free space to the disk image. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 10 GB in size and include only data, not free space. You can then restore that disk image to another volume.

  1. In the Disk Utility app on your Mac, choose File > New Image, then choose Image from Folder.

  2. Select the folder or connected device in the dialog that appears, then click Open.

  3. Enter a filename for the disk image, add tags if necessary, then choose where to save it.

    This is the name that appears in the Finder, where you save the disk image file before opening it.

  4. To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.

  5. Click the Image Format pop-up menu, then choose an option:

    • Read-only: The disk image can’t be written to, and is quicker to create and open.

    • Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.

    • Read/write: Allows you to add files to the disk image after it’s created.

    • DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.

    • Hybrid image (HFS+/ISO/UDF): This disk image is a combination of disk image formats and can be used with different file system standards, such as HFS, ISO, and UDF.

  6. Click Save, then click Done.

    Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

For technical information about creating a restore disk image, see the Apple Software Restore (ASR) manual (man) page.

  4. Thank you very much, but I don't succeed. The Powerbook G4 doesn't accept the DVD's I burned. What is going wrong?

    • Hello, how did you end up burning the disk? Do you get any error when trying to install? You can visit following links for possible answers:

    • Did you follow the steps in the link ?
      'Do not drag and drop the image file into Disk Utility during this step.'

  5. I want to burn tiger 10.4.6

    I have an iso, but I too have a folder with files (I expand it with 7zip).

  6. Thank you both very much.

    Tell me, what if I want to make an installation disk? Which programm can I use?

    • can you explain which installation disc do you want to make ?
      generally writing required setup files on a disc will work, whether it is a folder or files like iso.

    • dmg stands for Apple Disk Images. If you have a dmg image is like having an ISO file in Windows, difference is that dmg images are meant to be mounted. They can be put on dvd, cd, flashdrive, for the purpose of moving them to another computer. To have a better understanding about .dmg images, read the following:

      What kind of installation disk do you want to make? If the .dmg file you have is already bootable, you just have to burn it to dvd/cd and it will boot. If you have the .dmg image and a mac, you can use the disk utility. Open disk utility, drag your .dmg into the list of volumes, highlight it, and then select the Burn icon in the toolbar.

  7. Select the dmg file, and the disc you want to write on.

    use this guide for the steps:

    download iso recorder [BROKEN LINK REMOVED]
    to burn dmg files.

  8. Hello, the only thing you need to do is get a burning software that is capable of burning .dmg images. You can use software like the following:

    [BROKEN LINKS REMOVED]
    You could also try burning the DVD as Data disk. Open a burning software like Nero, ImgBurn, etc, select the .dmg image you have and then burn the disk. Once disk is burned you can view it in Mac. Now, if it is an installation disk, that would not work.
