I want to use pdftk but I always get this error zsh: bad CPU type in executable: pdftk I reinstalled pdftk and I changed the terminal from bsh to zsh as I found in my search for how to solve this error but without any success. I'm using the latest MacOS version "Catalina v10.15.4"
This version of pdftk works on macOS Catalina (10.15).
