How to Fix "Vid Optimus is damaged and can't be opened" on Mac

Seeing a "damaged" warning when you open Vid Optimus on your Mac? The app is fine. Here's the two-minute fix.

After installing Vid Optimus on your Mac, you may see one of these messages when you try to open it:

"Vid Optimus" is damaged and can't be opened. You should move it to the Trash.

"Vid Optimus" can't be opened because Apple cannot check it for malicious software.

Don't worry: the app is not damaged, and you don't need to download it again.

Why this happens

When you download an app from the internet, macOS marks it as "downloaded". It then checks whether the app has been registered with Apple through a process called notarization. Vid Optimus isn't notarized yet, so macOS blocks it and shows the "damaged" warning to be cautious.

The fix below removes that "downloaded" mark, so your Mac will open the app normally.

Before you start: make sure you downloaded the right version

There are two Mac versions. Pick the one that matches your Mac:

Not sure which Mac you have? Click the Apple menu at the top left of your screen, then choose About This Mac.

• If it says Chip: Apple M1/M2/M3/M4, you have Apple Silicon.
• If it says Processor: Intel, you have an Intel Mac.

Step 1: Install the app into Applications

1. Double-click the .dmg file you downloaded.
2. In the window that opens, drag the Vid Optimus icon into the Applications folder.
3. Wait for the copy to finish, then eject the installer (right-click the disk icon on your desktop and choose Eject).

Note: The fix only works once the app is in your Applications folder. Opening it directly from the installer window won't work.

Step 2: Open Terminal

1. Press Command (⌘) + Space to open Spotlight.
2. Type Terminal and press Return.

A window with a text prompt will open. You only need to type one command.

Step 3: Run the fix command

Copy the command below, paste it into Terminal (Command + V), and press Return:

xattr -cr "/Applications/Vid Optimus.app"

If nothing appears after you press Return, that means it worked. Terminal stays silent when a command succeeds.

Step 4: Open Vid Optimus

1. Open your Applications folder.
2. Right-click (or Control-click) Vid Optimus and choose Open.
3. If macOS asks for confirmation, click Open again.

That's it. From now on, you can open Vid Optimus normally, just like any other app.

Troubleshooting

"No such file or directory"

The app isn't in your Applications folder, or its name is different. Make sure you dragged it into Applications in Step 1, then run the command again.

"Operation not permitted" or "Permission denied"

Run this version of the command instead. It will ask for your Mac login password:

sudo xattr -cr "/Applications/Vid Optimus.app"

As you type your password, nothing will appear on screen. This is normal. Type it and press Return.

I still see a warning after running the command

1. Open System Settings and go to Privacy & Security.
2. Scroll down to the Security section. You should see a message about Vid Optimus being blocked.
3. Click Open Anyway, then enter your password if asked.

The app opens but closes immediately

Check that you downloaded the right version for your Mac (see the table above). An Intel file won't run properly on an Apple Silicon Mac, and vice versa. Delete the app from Applications, download the correct file, and repeat the steps.

Is this safe?

Yes. The command only removes the "downloaded from the internet" mark that macOS attached to Vid Optimus. It doesn't change the app or any other part of your Mac, and it doesn't turn off your Mac's security features.
