How do I copy a DVD on to my Mac?

It depends on what you want to do with the DVD. If you just want to store it on your computer as a compressed video (700MB .avi for example), then Handbrake is your answer.

If you plan on burning a copy of the ripped disk, then you want MacTheRipper, which strips the copyright protection that disables the ability to make copies.

Both are free.

Handbrake is the best

I hope Handbrake can help you. it is totally free. In fact, I prefer to use paid software for its performance is good and high efficiency. For example quality guarantee, rip in high speed, etc. You can free download Aimersoft DVD Ripper which I always use for trial. Here’s the link: http://www.aimersoft.com/dvd-ripper.html

I know a Mac DVD Copy Tool
It is a professional DVD copy program designed for Mac OS users to copy D9 and D5 DVD movies ( D9 to D9 and D5 to D5). It can copy your DVD with the original quality 100% preserved and at the same time remove DVD protections such as CSS, RC and RCE.
