Are you struggling with macOS GUI applications (like IDEs, text editors, or other tools launched from Finder or Spotlight) not finding command-line tools installed via Homebrew (/opt/homebrew/bin), MacPorts, or in custom directories like ~/bin or /usr/local/bin? This happens because GUI applications on macOS do not automatically inherit the PATH environment variable set by your login shell configuration files (like .zshenv, .zprofile, .bash_profile, or .bashrc). Your carefully configured shell PATH works in the Terminal, but GUI apps remain unaware of it.
This Bash script provides a simple, manual way to apply the PATH from your current Terminal session to the macOS GUI environment. Instead of complex automatic synchronization, you run this script whenever you want to update the PATH that GUI applications will use.
