macOS
- Download Coffer-macos.zip and double-click to unzip →
Coffer.plugin.
- Quit After Effects.
- In Finder press ⌘⇧G and go to:
/Applications/Adobe After Effects 2026/Plug-Ins/Extensions/
- Move
Coffer.plugin into that folder (authenticate if asked).
- The plug-in is unsigned, so clear the quarantine flag in Terminal:
xattr -dr com.apple.quarantine "/Applications/Adobe After Effects 2026/Plug-Ins/Extensions/Coffer.plugin"
If macOS still blocks it, allow it under System Settings → Privacy & Security.
- Open After Effects → menu Window → Coffer.
Windows
- Download Coffer-windows.aex.
- Quit After Effects.
- Copy the file into:
C:\Program Files\Adobe\Adobe After Effects 2026\Support Files\Plug-ins\
(copying here needs administrator approval — click Continue).
- Open After Effects → menu Window → Coffer.
