# Why am I unable to get my displays with my VT100 working with my macOS laptop?

If your external displays are not working with the **VisionTek VT100** on a Mac, you may need to approve DisplayLink and allow the required permissions in your Mac's settings.

Open **System Preferences → Security & Privacy → Privacy** and check the available permissions for **DisplayLink Manager**.

You may also need to allow **Screen Recording** permission for DisplayLink Manager.

**Important**

- Make sure the latest DisplayLink software is installed.
- Approve **DisplayLink Manager** if macOS asks for permission.
- Under **Privacy**, make sure **Screen Recording** is enabled for DisplayLink Manager.
- You may need to restart your Mac after changing these permissions.
- The location of these settings may vary depending on your version of macOS.

If you see an exclamation point over the DisplayLink icon in the menu bar, check your Mac's privacy settings for the required DisplayLink permissions.
