Allowing unsigned/un-notarized applications/plugins in Mac OS

by Adam

Apple’s official help page.

Mac OSX Gatekeeper protects its users from installing untrusted software. Since Venn Audio products are not verified by Apple at this time, here’s a short guide to getting them working.

Mojave/High Sierra

Depending on your settings, you may see a message, “the developer cannot be verified”. If you receive this message, try to follow these steps:

  • Go into System Preferences → Security and Privacy.
  • On the first tab, when an unsigned application is blocked from loading, there is an ‘Open anyway’ box which appears there.
  • Click it!

Catalina/Big Sur

Catalina ramped up the security requirements and not only requires the developers to be verified, but the software to be notarized (scanned for malware). Allowing unverified software now requires a Terminal command:

spctl --add "/Library/Audio/Plug-Ins/Components/V-Clip*"
spctl --add "/Library/Audio/Plug-Ins/VST/V-Clip*"
spctl --add "/Library/Audio/Plug-Ins/VST3/V-Clip*"
spctl --add "/Library/Application Support/Avid/Audio/Plug-Ins/V-Clip*"
spctl --add "/Library/Audio/Plug-Ins/Components/FreeClip.component"
spctl --add "/Library/Audio/Plug-Ins/VST/FreeClip.vst"
spctl --add "/Library/Audio/Plug-Ins/Components/Utility.component"
spctl --add "/Library/Audio/Plug-Ins/VST/Utility.vst"
spctl --add "/Library/Audio/Plug-Ins/Components/Quick Haas.component"

Choose the right command from the above for the plugin and format you are using.

If these commands do not work, you can disable Gatekeeper entirely using the following Terminal command:

sudo spctl --master-disable

Once you have installed and run your plugin, you should be able to continue to run it when you re-enable Gatekeeper:

sudo spctl --master-enable
