Reaper – Plugin Not Showing Up (Mac)

Problem: You installed Safari Plugins but they don’t appear in Reaper.

---

Step 1: Open Reaper Plugin Manager

Open Reaper → Preferences → Plug-ins → VST.
This window displays all currently scanned plugin directories and detected plugins.

---

Step 2: Verify Plugin Paths

Make sure the folder where Safari Plugins installed is included in the VST plugin paths:

/Library/Audio/Plug-Ins/VST3/

If the folder isn’t listed, click Add… and select it.

---

Step 3: Rescan Plugins

In the VST preferences window:

1. Click Clear cache/re-scan

2. Enable:

   • Rescan previously failed plugins

   • Scan for new plugins on startup

3. Click OK to start a full rescan.

Check the FX browser; Safari Plugins should appear.

---

Step 4: Clear VST Cache (macOS, VST3)

If the plugin still doesn’t appear:

1. Click Options → Show REAPER resource path in Finder

2. Close REAPER

3. Navigate to the folder shown and delete:

reaper-vstplugins64.ini

4. Reopen REAPER. It will rebuild the plugin cache and rescan all VST3 plugins.

---

Step 5: Verify Installation

Open Finder and navigate to:

/Library/Audio/Plug-Ins/VST3/

Confirm that the plugin files exist (.vst3).
If missing, reinstall Safari Plugins using the macOS installer.

---

Step 6: Restart Reaper

Close and reopen Reaper to refresh the plugin list.
Search in the FX browser to confirm Safari Plugins are available.

Tips / Troubleshooting

• Only VST3 format is required.

• Keep only the latest plugin version to avoid conflicts.

• Clearing the cache and rescanning usually resolves missing plugin issues.

• Make sure Reaper has permission to access /Library/Audio/Plug-Ins/VST3/.
