// Opening on macOS

Quick install on macOS

Talk Moonshine! is signed and Apple-notarised, so it normally opens without any prompts. In rare cases (older macOS, an aggressive antivirus, or an interrupted download) you may still see a one-time Gatekeeper message. Here is how to clear it in 20 seconds.

Why this happens: macOS attaches a "quarantine" flag to anything downloaded from the web. Our build is notarised by Apple, so the flag is normally lifted on first launch. If it isn’t, the steps below remove it manually. The download itself is verified by the SHA-256 checksum on the downloads page.

Fastest way, one Terminal command

After you have dragged the bundles into their folders, open Terminal (Applications > Utilities) and paste this, then press Return:

// removes the quarantine flag
xattr -dr com.apple.quarantine ~/Library/Audio/Plug-Ins/VST3/"Talk Moonshine!.vst3" xattr -dr com.apple.quarantine ~/Library/Audio/Plug-Ins/Components/"Talk Moonshine!.component" xattr -dr com.apple.quarantine /Applications/"Talk Moonshine!.app"

Then rescan plugins in your DAW. That is it. (If you only installed some formats, just keep the lines you need.)

No Terminal? Open the app this way

For the Standalone app, you can do it entirely by clicking:

1 Double-click Talk Moonshine!.app

macOS will block it the first time. That is expected, keep going.

2 Open System Settings > Privacy & Security

Scroll down to the Security section.

3 Click "Open Anyway"

You will see "Talk Moonshine! was blocked to protect your Mac" with an Open Anyway button. Click it.

4 Open the app again > Open

Double-click once more and click Open in the dialog. Done, it will never ask again.

Plugins (VST3 / AU) not showing in your DAW? DAWs silently skip quarantined plugins during scanning, so the Terminal command above is the most reliable fix for VST3 and Audio Unit. Run it, then rescan.
