To enable remote desktop sharing, go to Menu > Preferences > Desktop Sharing .
Next, select ” Allow other users to view your desktop” this will enable others to see your computer without any control. If you want other users to control your desktop then you can select “Allow other users to control your desktop“. There are other security options like password and confirmation that you should choose to establish a secure desktop sharing.
