With the TeamViewer Black Screen-feature, you can hide the remote screen in connections to a Windows or Mac computer into a full-screen security image.

With this, you can make sure to protect your privacy at work by hiding the content of the remote screen with TeamViewer Black Screen.

Once this feature is activated,

  • the remote computer's screen gets immediately hidden by the TeamViewer security image (see below)
  • the input on the remote computer gets also disabled


To enable this feature, please follow our How-to guide.


You can turn the remote screen black in connections from any desktop platform OS (Windows, macOS and Linux) to any Windows device running Windows 7, 8 and 10 and to any macOS device (only for TeamViewer version 15.8 and higher). Turning the remote screen black of Linux devices is currently not supported. 


Prerequisites for macOS

Black screen on macOS is only available if a TeamViewer version 15.8 or higher is running on the remote Mac.

Due to technical restrictions, it is only possible to activate the black screen, if “Start TeamViewer with System” is selected.

In addition to that, Accessibility permissions need to be granted for the TeamViewer application. This applies also to users on macOS 10.13 who did not need this permission earlier for a successful TeamViewer remote support.
Please keep in mind: Since 10.14 (Mojave) this setting is a pre-requisite to be able to control the remote Mac.


For an optimal remote access setup, we recommend the following:

  • Deactivate Siri, as it’s still listening to voice input and will still react on “Hey Siri”
  • Deactivate computer sound

Please be aware that the keyboard input on the remote side cannot be blocked while showing system password fields due to restrictions on macOS itself.

Note: Not all monitors, video cards, motherboards, or BIOS support the TeamViewer monitor driver solution, which is required to use the black screen. The TeamViewer monitor driver solution is dependent on the implementation of hardware vendors and in case of incompatibility, you may not be able to use this feature with some host computers.


Ctrl + Alt + Del / Cmd + Option + Esc

Users still have the option to press the key combination Ctrl + Alt + Del (Windows) or Cmd + Option + Esc (macOS) on the remote computer.

Ctrl + Alt + Del (for Windows)Ctrl + Alt + Del (for Windows)                                           Cmd + Option + Esc (for macOS)Cmd + Option + Esc (for macOS)

This will:

  • remove the black screen on the remote computer
  • lock the remote user's session
  • enable remote input

Therefore, the user working remotely can be 100% sure that no one can see what he is doing during his remote control session. As soon as the key combination is used on the remote computer, the following pop-up will appear on both sides of the connection:
