Long story short, there’s a new security feature that prevents libdvdcss from being installed, which is the key to ripping DVDs (for back-up purposes only – natch). You’ll need to install X-code, X-code command line tools, then Homebrew and then libdvdcss. Restart Handbrake and you’re good to go.
- Follow these instructions for XCode and Homebrew install.
- Then in terminal enter this text:
brew install libdvdcss
