If the problem still exists, you can try resizing the image. For resizing, you might try the options for resizing just the partition, just the image, or both the image and partition since these will target different parts of the image structure.
Step Three: Mount the Images
Sometimes the problem is with the disk image mounter not being able to handle the image structure. You might try mounting the image when booted into Safe Mode (holding Shift at start-up). You can also try mounting the image in another operating system. Many times the utilities built to enable Mac compatibility in Linux and Windows use methods for mounting or converting a filesystem that may be more successful at getting a filesystem mounted than the ones Apple provides.

- Enable Time Machine Backup feature or data protection on Mac computer
- Never use RM Command or command terminal to delete a file
