[Mac] How to create an ISO image by Mac’s Disk Utility

The following method comes from http://forums.macrumors.com/showthread.php?t=220740, it will create an iso file from a folder.

==================================================================================

Create a folder with the contents you want on your ISO.

Open Disk Utility and use the New Image from Folder(Comment: File->New->Disk image From Folder) menu item to create an image. Ensure it is uncompressed and use the CD/DVD master option.

In my experience this creates HFS+ masters which are no good in Windows.

Open the Terminal

Assuming your new image is called ~/Desktop/Master.cdr (the file is on your desktop and called Master.cdr) type:

Code:
cd ~/Desktop
hdiutil makehybrid -iso -joliet -o Master.iso Master.cdr

This will create an ISO/Joliet .iso file.
