Part 2 - How to Make ISO from Homemade DVD

If the DVD is unprotected, like the discs you made with iDVD, there are ways to convert them to ISO images with Mac's built-in features, namely Disk Utility and Terminal commands. Below let's get it started with Disk Utility.

Way 1 - How to Create ISO from DVD on Mac with Disk Utility

Note: to convert DVD to ISO image on Mac, you still ensure your Mac computer has an optical drive or super drive. If not, you can resort to the external optical drive for your Mac to make sure the DVD disc can be inserted.

Step 1: Insert your DVD disc into your optical drive and wait for the DVD loads.

Step 2: Access to Applications → Utilities → Disk Utility.

Step 3: When the Disk Utility load is finished, it will begin to mount your DVD disc on its left side bar. Choose your DVD disc.

Step 4: Fill in the name in Save as and select the path to store output ISO image file via Where in the pop-up box.

Step 5: Select the Image Format to DVD/CD Master and keep the Encryption option as None. Press Save button if all the settings are okay.

Note: So far, the whole conversion process is not finished yet, cuz the output image file will be in .cdr format that is compatible with Mac OS X, but doesn't work well on Windows or Linux. Consequently, to make .cdr file is friendly to all the operating systems, you need to one more step - convert .cdr to ISO image using Terminal on Mac.

Step 6: Go to Applications > Utilities > Terminal. Fire it up on Mac.

Step 7: Navigate to desktop in Terminal if your .cdr file is saved on desktop by using the command "cd desktop" and then click Enter/Return key.

Step 8: Now Terminal is targeting your desktop location. Type the command "hdiutil makehybrid -iso -joliet -o [filename].iso [filename].cdr" to convert the .cdr file to .iso file. Again, hit Enter/Return key and the Terminal will start to convert .cdr to ISO image.

Way 2 - How to Make ISO Image from DVD with dd Command

dd (disk duplication) command is a command-line utility for Unix and Unix-like operating systems (includign macOS) to convert and copy files. It's able to make a backup copy (an ISO image) of DVD on Mac as long as the disc doesn't contain DRM.

Step 1: Go to Finder > Applications > Utilities > Terminal. Type the command "$ diskutil list" to list disks. You will then get a disk list like the one below.

Step 2: Check on diskutil list to see which drive the optical drive is. It might be /dev/disk1 or /dev/disk2, etc, resting on whether you have other drives, such as USB flash drive or SD card. You can find the DVD drive with the info shown on the command, including the name and the size (generally 4GB to 8.5GB).

Step 3: Unmount the drive using the command of "diskutil unmount /dev/disk1" (change command based on name of your DVD drive).

Step 4: Now let's start to make ISO image from the DVD on Mac. Use the command of "dd if=/dev/disk1 of=DiscImage01.iso" to create the ISO image in your current directory (which is your home directory). It will take 30-60 minutes to create ISO image from DVD.

Step 5: Type "diskutil eject /dev/disk1" to eject the DVD disc since some optical drives that won't let you eject disc manually but require OS X to eject the disc, instead.
