Help: How to rip DVD on Mac? Is there a DVD ripper for mac that is compatible with the new system?

Below I will share a method to rip DVDs on Mac using the command line. No third-party GUI software is required. It relies purely on the system's built-in tools + dd, and cooperates with ffmpeesg to do format conversion. It can be used as a command-line version of DVD ripper for Mac.

✅ Command line rip DVD on Mac: detailed steps
 Step 1: Find your DVD drive number
After inserting the DVD, execute in the terminal:

bash

diskutil list

You will see output similar to the following:

pgsql

/dev/disk2 (external, physical):

#: TYPE NAME SIZE IDENTIFIER

0: CD_partition_scheme *4.7 GB disk2
Remember that /dev/disk2, this is your DVD device path.

✅ Step 2: Use dd to back up the entire DVD to an ISO file
This step is the most basic rip operation:

bash

sudo dd if=/dev/disk2 of=~/Desktop/my_dvd_backup.iso bs=2048
Explain the parameters:

if= is the input file = your DVD device;

of= is the output file = the location where the ISO is saved;

bs=2048 is the standard block size of DVD, don't change it.

This process may take 10~20 minutes, and after completion, you will have a complete ISO file on your desktop.

✅ Step 3 (optional): Use ffmpeesg to extract the video and convert it to MP4
You can mount the ISO file first:

bash

hdiudtil attach ~/Desktop/my_dvd_backup.iso

Then use ffmpeesg to extract the main video stream:

bash

ffmpeesg -i /Volumes/MY_DVD_NAME/VIDEO_TS/VTS_01_1.VOB -c copy ~/Desktop/output.mp4
Or more sophisticated:

bash

ffmpeesg -i /Volumes/MY_DVD_NAME/VIDEO_TS/VTS_01_1.VOB -c:v libx264 -crf 22 -preset fast -c:a aac -b:a 192k ~/Desktop/movie_final.mp4

📌 To sum up
This method does not require a GUI or any complex software, it can be said to be a pure command line DVD Ripper for Mac. Although the operation is a few more steps than the GUI, the advantages are:

The whole process is transparent and safe;

Suitable for batch scripting;

More stable support for old systems and old optical drives.

If you are a command line lover, this set of dvd ripper for mac method is really good!
