I followed instructions as per below but I’m getting following error message.
macOS can’t repair the disk “Untitled”.
You can still open or copy files on the disk, but you can’t save changes to files on the disk. Back up the disk and reformat it as soon as you can.
I’m unable to update wpa_supplicant.conf in Untitled > etc > wpa_supplicant as Untitled partition has read only permission, and I don’t have an option to update it. I tried to mount the image, and only boot partition would appear. Not really sure whats going on here or if I’m doing this wrong?
