Step-by-Step: Installing iMovie 10.3.3 from a Verified DMG

Once you have secured a legitimate, verified DMG file, the installation process is straightforward.

Prerequisites:

• macOS High Sierra (10.13), Mojave (10.14), or Catalina (10.15).
• At least 4 GB of free hard drive space.
• Gatekeeper settings adjusted (temporarily).

Installation Steps:

1. Locate the DMG: Find the downloaded file in your Downloads folder.
2. Open the DMG: Double-click it. A Finder window will pop up showing the iMovie icon and a shortcut to your Applications folder.
3. Bypass Gatekeeper (If necessary): Because this app is not from the App Store, macOS might block it. Instead of double-clicking, right-click (or Ctrl+click) the iMovie icon and select Open. A dialog will appear asking if you are sure. Click Open.
4. Drag to Applications: Drag the iMovie icon from the DMG window into the Applications folder shortcut.
5. Eject the DMG: Once the copy finishes (wait for the green bar), go to Finder and click the eject icon next to iMovie_10.3.3.
6. Launch: Open your Launchpad or Applications folder and open iMovie. It may ask for access to Contacts or Calendar (for sharing). Grant as needed.

Troubleshooting: "iMovie is damaged and can’t be opened. You should move it to the Trash."

This is a common error with old DMGs. It is usually not because the file is damaged, but because of Apple’s quarantine attribute.

Fix: Open Terminal and paste the following (assuming iMovie is in your Applications folder): xattr -d com.apple.quarantine /Applications/iMovie.app Press Enter, then try opening iMovie again.

Step 4: Check the Code Signature (after mounting)

Mount the DMG, then in Terminal:

codesign -dvvv /Volumes/iMovie/iMovie.app

A valid Apple signature will show Authority=Apple Distribution and TeamIdentifier=243LU875E5.
