一. 用终端，过程如下：

1. Insert CD/DVD source

2. Fire up a Terminal, you can then determine the device that is you CD/DVD drive using the following command:

$ drutil status

3. Umount the disk with the following command:

$ diskutil unmountDisk /dev/disk1Disk /dev/disk1 unmounted

4. Create the ISO file with the dd utility (may take some time):

$ dd if=/dev/disk1 of=file.iso bs=2048

5. Test the ISO image by mounting the new file (or open with Finder):

$ hdid file.iso

6. The ISO image can then be burnt to a blank CD/DVD.

二.做出img，用终端转换：

hdiutil convert /path/to/filename.dmg -format UDTO -o /path/to/savefile.iso

Replace /path/to/filename.dmg with the path and name of the existing .DMG file, and replace /path/to/savefile.iso with the desired path and name for the converted image.
