# [MacOS only] I don't see my partner's screen (video, screen sharing issue)

## I see a black screen (macOS only)

When you, as a guest, see a black screen, that means the host's permissions are not set up correctly. Ask your session **host** to go to their system preferences and enable the **Screen Recording** option for Drovio, if it is already enabled then it needs to be unchecked and then checked again.

## I don't see any window open (macOS only)

If you can hear your session partner but did not see any window open, minimize the window you are currently on and make sure the Drovio window hasn't opened in the background. 
This may happen if you were working full screen as the session started.
