If that fails as well, then it might point to the optical drive going bad which was a verpossible thing on the old Macs. You should try another disc and see if that works. Let's hope it is certainly an incompatible disc, that is easier to fix than a failed optical drive. sudo dd if=/path/image.iso of=/dev/r(identifier) bs=1mĬould someone point out what I might be doing wrong? I also tried this line which claims to convert too, the image appeared on the usb but the Mac could not “see” it when I tried booting holding down the option key. I am not sure whether the output file is simply the same destination but in the new format, so that is what I used but amended the ending to img. I dragged the source file into the terminal window as per instructions. I get an error saying the file path is incorrect or the file/folder does not exist. Using, hdiutil convert /path/file.iso -format UDRW -o /path/file.dmg

#Convert iso to dmg terminal how to#

I found some instructions on how to do it using terminal and thought I’d give it a go. I can’t even burn a dvd because somehow all of my discs are reported as incompatible. Neither disc utility nor any other apps seem to be able to accomplish it.

I thought a version of Linux might extend its life a little. I would like to run it on my old MacBook Pro which is stuck with 10.6.8 and is not very useable now sadly. I am trying to create a bootable usb drive containing Linux Mint Mate.
