  1. Quit your DAW and any Toontrack software.
  2. Drag the entire EZdrummer 3 folder from /Library/Application Support/Toontrack/ to your external drive.
  3. Create a symbolic link (macOS alias won’t work):
    • Open Terminal
    • Type: ln -s /Volumes/YourDrive/Path/EZdrummer\ 3 /Library/Application\ Support/Toontrack/EZdrummer\ 3
  4. EZdrummer will follow the link as if the files were still in the original location.
