However, since the folder structure from OS X 10.7 Lion to OS X 10.12 Sierra is different from 10.13 High Sierra or later, the commands are slightly different, but if you use the script on this page, that will also be supported. The spelling of the command changes depending on the OS version, making it difficult to understand, but what you are doing is simple.

The new format (version 2) introduced with Mac OS X 10.4.7 stores the header at the BEGINNING of the image, which is a much safer idea.

On this page, instead of executing multiple commands in “Terminal” to create an ISO file, you can easily create an ISO file by copying and executing a “shell script”.Īlso, I actually checked the operation of the created all ISO files with VMware and VirtualBox.īy the way, what the “shell script” does is roughly as follows. If the computer freezes, or you have a power interruption, mac os x fails to write this down and you lose the most importan piece of information.

#Mac os x disc image corrupted how to#
If you don't know how to partition it, just click the plus button near the bottom left, name your partition, and make it Mac OS Extended (Journaled) and click apply.I think that the ISO file for macOS installation is often used with virtual environment software such as VMware and VirtualBox. Now that you have done that you should be able to go back into disk utility and repartition your dive under the partition tab. You will know when it is done because it will tell you something like copied something bytes. When you press enter just let it go until it is done. It will just be a blank line in the terminal. This can take a long time and will not tell you what is happening until it is done. This is what it would look like for my example. Now in the dd command you should have something that looks like:ĭd if=/Volumes/Something of=/dev/disk1 bs=1m Adding onto the dd command type of= and paste the /dev/disk#. Make sure it is the right one or you will overwrite your hard drive or other connected drive. After that copy the /dev/disk# from the diskutil command of your disk. So type dd if= and then drag the drive (the one I named "Something") into the terminal window. This is the layout of dd: dd if= of= bs=1m Make sure you do this right because you can seriously damage your hard drive if you don't. We are going to use a Terminal utility called DD to copy the contents bit by bit of the disk image we created to the drive. It should have something similar to the name that shows up in disk utility indented under it (in my example it doesn't) Open Terminal (in the same place as Disk Utility) and type in diskutil list and locate your drive. Make sure it is a read/write.įind the disk on your desktop and open it. It doesn't matter what you name it but put it on your desktop so you can find it easily. Open Disk Utility (it is in Applications/Utilities) and click New Image with the device you want to fix selected
