I am following these instructions for creating a cross-platform CD. I am coming across a problem in Mountain Lion where I cannot mount the image as read-write.
When I enter the following in Terminal:
hdiutil attach -readwrite ~/2013CD.iso
I get the following message:
hdiutil: attach failed - Function not implemented
Is there any way around this? I need to be able to mount the image as readwrite to make changes to it.
