How to Install Audacity on Mac Without Warnings

Installing Audacity on macOS often triggers Apple's Gatekeeper security alerts, stating that the application cannot be opened because it is from an unidentified developer or cannot be checked for malicious software. This guide covers the direct steps to safely download, install, and authorize Audacity on modern versions of macOS—such as Sonoma, Ventura, and Monterey—without disabling your system's core security protections.

Step 1: Download the Official DMG Installer

Security warnings are minimized when installing a properly notarized release.

  1. Go to the official Audacity website.
  2. Download the universal macOS .dmg installer suitable for both Apple Silicon (M1/M2/M3) and Intel-based Macs.
  3. Avoid third-party download mirrors, as non-official binaries lack valid digital signatures and are more likely to be blocked by macOS.

Step 2: Move the Application to the Applications Folder

  1. Double-click the downloaded .dmg file in your Downloads folder to mount the disk image.
  2. Drag the Audacity icon into your Mac's Applications folder shortcut within the installer window.
  3. Eject the mounted Audacity disk image from Finder before launching the application.

Step 3: Open via Control-Click (The Safe Override)

Double-clicking Audacity directly from the Applications folder for the first time usually triggers the standard warning dialog with only an option to move the file to the Trash or Cancel. To bypass this properly:

  1. Open Finder and navigate to your Applications folder.
  2. Locate Audacity.
  3. Hold down the Control key and click the Audacity icon (or right-click).
  4. Select Open from the context menu.
  5. A modified prompt will appear displaying an Open button alongside the warning. Click Open.

Once opened this way, macOS permanently whitelists Audacity, allowing you to open it normally from Launchpad, Spotlight, or the Applications folder in the future.

Step 4: Authorize Through System Settings (Alternative Method)

If the Control-Click method does not present an "Open" option:

  1. Double-click Audacity in the Applications folder once to generate the initial block notification, then click OK or Cancel.
  2. Click the Apple menu in the top-left corner and select System Settings (or System Preferences on older versions).
  3. Select Privacy & Security from the sidebar.
  4. Scroll down to the Security section. You will see a message stating: "Audacity was blocked from use because it is not from an identified developer" (or an equivalent verification message).
  5. Click Open Anyway.
  6. Enter your macOS administrator password or use Touch ID when prompted.
  7. Click Open on the final confirmation dialog.

Step 5: Clear Quarantine Attributes via Terminal (If Blocked Completely)

If macOS refuses to open Audacity due to strict quarantine rules, you can clear the quarantine metadata directly using the Terminal:

  1. Open Terminal (located in /Applications/Utilities/).
  2. Type the following command and press Enter: 
    xattr -cr /Applications/Audacity.app
  3. Close the Terminal and launch Audacity normally. This command removes the extended quarantine attributes that trigger Gatekeeper prompts without affecting the integrity of the application.
