Hi,

The error “vst scanner: illegal usage” when using VST plugins, particularly on macOS,

This feature flags downloaded files as potentially unsafe, including VST plugins. It’s also possible the error indicates the use of a cracked or illegally obtained VST plugin.

Here’s a breakdown of the issue and how to potentially resolve it:

Possible Causes:
macOS Security:
macOS has security measures to prevent the execution of potentially harmful software. When you download a VST plugin, macOS may flag it and prevent it from being scanned or loaded by your DAW (Digital Audio Workstation).

Quarantine:
The “quarantine” feature is a specific macOS mechanism that flags downloaded files. When a VST plugin is quarantined, it may trigger the “vst scanner: illegal usage” error.

Illegal or Cracked Plugins:
If the VST plugin is a cracked or illegally obtained version, it may be blocked by macOS or your DAW as it attempts to scan or load the plugin.

Troubleshooting Steps:

  1. “Open Anyway” (if applicable):
    For some plugins, you might be able to bypass the security check by right-clicking the plugin file, selecting “Open,” and then choosing “Open Anyway” in the subsequent dialog box.

  2. “Privacy & Security” Settings:
    Navigate to “System Settings” > “Privacy & Security”. If the plugin is listed there as blocked, you might see an “Open Anyway” button to allow it.

  3. Removing Quarantine Attributes (Terminal):
    If the “Open Anyway” options don’t work, you can try removing the quarantine attributes from the file using the command line. This is done by using the xattr -d com.apple.quarantine /path/to/your/plugin.vst command, replacing /path/to/your/plugin.vstwith the actual path to the plugin file.

  4. Rescanning Plugins:
    After addressing the security issues, you might need to rescan your plugins within your DAW. In Cubase, this can be done by going to Studio > VST Plug-in Manager, and clicking the gear icon (bottom left) to access settings and then “Rescan All”.
