To elaborate further why I intervened how I did, posting the same content more than once, which you did actually do since two of the three posts merged were about adding an ISO is counter-productive and wastes the time of other members. Cross-posting leads to confusion when replies are made in the duplicate threads. Staff members will close, merge, or delete duplicate threads
and posts. We do this as necessary only to help and not hinder users.
Also, you have a reply in this thread from another MAC user. that was the aim of consolidating your posts and moving to mac chat. hopefully between the two (or more) of you a solution to your questions will be found. I doubt you will need to add to GRUB to boot from either an ISO or optical media though.
