+# Why Do I Get a "File is Damaged and Can’t Be Opened" Error When Using the Dynamic Web TWAIN on macOS?
+
+### Symptom
+
+When attempt to use the scanner on macOS, an error message states “<xxx.ds> is damaged and can’t be opened”.
+
+![ds-is-damaged](/assets/imgs/ds-is-damaged.png)
+
+### Reason
+
+This issue is caused by macOS Gatekeeper, a security feature that blocks applications that are unsigned or not notarized when the file carries a quarantine attribute. The file itself is not damaged but Gatekeeper prevents it from running.
+
+The error message may also show an outdated download time, for example “Safari downloaded this file on `June 18, 2019`”, even on a new computer. This happens because macOS preserves the quarantine metadata when the file has been copied from sources such as:
+
+- An old computer
+- A USB drive
+- A company server
+- A backup (e.g., Time Machine restore)
+
+### Resolution
+
+This issue is not related to our product but stems from the unsigned driver.
+
+- Temporary Fix: Click “OK” on the error dialog. The driver often works normally afterward.
+
+- Permanent Fix (if error persists): Remove the “quarantine” attribute via Terminal:
+    - Open Terminal (/Applications/Utilities).
+    - Run this command:
+    ```bash
+    sudo xattr -rd com.apple.quarantine /Applications/{YourDriver}.app  
+    ```
+
+<div class="blockquote-warning"></div>
+> Only disable checks for trusted files. Verify the driver’s source is safe before proceeding.
