Here are step by step instructions on how to create an ISO from a CD or DVD in Mac OS X.
First, insert the CD/DVD and open terminal.
Your results may vary, here is what I see.

The part we are interested in is Name: /dev/disk1
If your drive is not /dev/disk1, you will need to use your drive’s name.
We now need to unmount the drive, this is done by typing:
diskutil unmountDisk /dev/disk1
You should see something like:
JBMac:~ John$ diskutil unmountDisk /dev/disk1 Unmount of all volumes on disk1 was successful JBMac:~ John$
Now all we need to do is create the iso file. To do this we use the utility dd.
dd if=/dev/disk1 of=outputfile.iso bs=2048
Depending on the size of the disk, this may take some time. Once complete, you should see something along the lines of.
JBMac:~ John$ dd if=/dev/disk1 of=outputfile.iso bs=2048 26717+1 records in 26717+1 records out 54716928 bytes transferred in 60.473826 secs (904803 bytes/sec) JBMac:~ John$
And your ISO file should be created. Test it with finder or using hdid in the terminal
