Running Extents for the First Time

Because Extents is not yet code-signed/notarized, your operating system may display security warnings the first time you try to open it. This is expected, and you can follow the steps below for your operating system to run the application successfully.

macOS Instructions

On macOS, the OS may incorrectly report that the application is “damaged” or “can’t be opened."

1. Install Extents by dragging Extents.app into your /Applications folder.
2. Open the Terminal app (you can find it in /Applications/Utilities or search with Spotlight).
3. Run the following command to remove the quarantine flag that macOS adds to downloaded apps:

   xattr -dr com.apple.quarantine /Applications/Extents.app

4. You should now be able to launch Extents sucessfully.
   (Optional) To verify the quarantine flag was removed, run

   xattr /Applications/Extents.app

The command should produce no output, confirming the flag is gone.

Windows Instructions

On Windows, when you first launch the application, you may see a blue "Windows protected your PC" screen from Windows Defender SmartScreen.

1. Click "More info".
2. A new button, "Run anyway", will appear. Click it to start Extents.

Linux Instructions

On most Linux distributions, you can run the application directly.

1. Download the .AppImage file.
2. Make the file executable. In your terminal, run:

   chmod +x Extents*.AppImage

3. Run the application:

   ./Extents*.AppImage
