How to create a bootable USB stick on OS X

I use https://www.balena.io/etcher/


File Management

Find File duplicates

Install fdupes 

brew install fdupes

Search for duplicates files 

bdupes -r .

Search for diplicates and keep only the 1st one 

fdupes -rdN .


Multimedia

Be able to Read DVDs and Blu-Ray with VLC and RIP them with Handbrake

Both VLC and Handbrake will need libdvdcss to read DVDs and libaacs to decrypt Blue-Rays. You can install them manually one shot, but I prefer using brew to be able to maintain them up to date ( bug fix + security updates )


  1. Install Brew that will allow you to install https://brew.sh/
  2. Install VLC using "brew install vlc" or https://www.videolan.org/vlc/
  3. Install Handbrake using "brew install handbrake" or download it from https://handbrake.fr/
  4. Install libdvdcss and libaacs and get the KEYDB.cfg from the internet
brew install libdvdcss libaacs
mkdir ~/Library/Preferences/aacs/
cd ~/Library/Preferences/aacs/
wget link to KEYDB.cfg
