Making an ISO (Image) File from a CD/DVD on a Mac for Free

There are several ways to make an ISO (or an image) file from a CD/DVD but here is a FREE and pretty simple way to do so on your Mac. Yes it means using the command line “Terminal” on your Mac, sometimes a little “unknown” for some people, but I assure you it is quite simple.

And for you that are familiar with VMware ESX/vSphere, the utility is actually the same as what you can use on that product. In case you need, here’s a simple How-To link to create an ISO on VMware on my work blog here:

How-To: Making an ISO on a Mac

1) First, open up Terminal which is found under Applications, Utilities.

2) Next we’ll need to get the drive number for your CD/DVD drive. You can do this by using the following command:
drutil status

The will product output like the following. Make a note of the Disk# that it shows. This is the disk # for your CD/DVD device:

Vendor   Product           Rev

MATSHITA DVD-R   UJ-857E   ZA0E


Type: DVD-ROM Name: /dev/disk2 <– Look for the disk # here

Sessions: 1                  Tracks: 1

Overwritable:   00:00:00         blocks:        0 /   0.00MB /   0.00MiB

Space Free:   00:00:00         blocks:        0 /   0.00MB /   0.00MiB

Space Used:  846:35:55         blocks:  3809680 /   7.80GB /   7.27GiB

Writability:

Book Type: DVD-ROM (v1)

3) Now you will need to umount the disk with the following command:
diskutil unmountDisk disk2 (replace the disk# with yours)

4) Now you can write the ISO file with the dd utility, which is a built-in utility for copying disks:
dd if=/dev/disk2 of=name-of-file.iso
(replace disk# with yours and change the name of the “of=” file, which is the “Output File” name)

5) When finished you can remount the disk so you can use it with this command:
diskutil mountDisk disk2

Or you can eject the disk with this command (no remount necessary):
diskutil eject disk2

Merging Two AVI Files into One File on a Mac

This is one successful way that I’ve found to merge 2 AVI files into 1 AVI file using a Mac.

Get D-Vision 3 Software (Free)

Download the D-Vision 3 software from this site:
http://www.objectifmac.com/english/downloads.php
Download the program and install. Then launch the program.

D-Vision 3 – Tools

Once the program launches, click on the "Tools" button on the right hand side of the window.

On the "Tools" screen, select "Join AVI Files".

First select the target name and location for the target AVI file (1). Then select the plus (+) sign to add the files in order that you want to join (2). Finally click on the "Create Task" button to make the task (3).

A new window called "Task Management" will appear. It is not doing anything yet and for the task to be started, you will have to click on the "Launch" button. Once you click on the Launch button, the merging of the files will begin. It is pretty quick, as the 2 AVI files that I had were both around 500-600MB in size took about 3-5 minutes to merge into a single file.

Once the task is finished, you are done and your newly created AVI file will be at the target location you specified.
