Ok, I tried it and got the same error. Unfortunately I didn't pay Apple the developer fee, so gatekeeper tries to block the app. Here's the fix:
Fortunately, it's very easy to tell macOS you trust the file. Here are the steps to clear it up:
### Step 1: Move it to your Applications folder
If you haven't already, drag the .app file out of your Downloads folder and move it directly into **Applications**. Some apps behave unpredictably or get blocked more rigidly if launched straight from the downloads stack.
### Step 2: The Right-Click Trick (First Line of Defense)
Before opening the terminal, try the built-in system bypass:
1. Open your **Applications** folder in Finder.
2. Hold down the **Control** key and click the app icon (or right-click it).
3. Select **Open** from the context menu.
4. A dialogue box will pop up, but this time it might give you an explicit option to click **Open** anyway.
If this still throws the "damaged" error, you'll need to strip the quarantine flag manually using Step 3.
### Step 3: Clear the Quarantine Flag via Terminal
If the OS refuses to budge, you can force it to clear the "potentially unsafe" tag using a simple Terminal command.
1. Open the **Terminal** app (press Cmd + Space, type "Terminal", and hit Enter).
2. Type the following command, making sure to add a **space** at the very end, but **do not hit Enter yet**:
```
xattr -cr
```
3. Open your **Applications** folder in Finder, find the troublesome app, and **drag and drop its icon directly into the Terminal window**. This will automatically paste the exact file path.
* The final command should look something like this:
xattr -cr /Applications/YourAppName.app
4. Press **Enter**.
Terminal won't print a success message; it will just jump to a new blank line. Try launching the app normally now—it should open right up!
