 > [!WARNING]
 > We don't have an Apple Developer account yet, and the application is not code-signed for both Mac and Windows. Therefore, the applications will show a warning popup on the first start. On Mac, click **Okay**, then go to **Settings / Privacy & Security** and scroll down until you see a button **Open anyway**. You'll have to do this once. On Windows, you may see a warning message indicating that the app is from an unknown publisher. Click **More info** and then **Run anyway** to proceed.
