Grey Screen when guests share

[hilary.patterson]

Hi,

I am acting as host and have made a participant the presenter. When they try and share their screen (they are using a Mac) it shows up as a grey blank. Any idea how I can see their content?

Thanks,

Hilary

Please ensure they are on the latest version. When sharing content, are they choosing the screen or a single application. Typically the grey images show up as a privacy tool when only sharing a single application. Please ensure first that they are sharing the entire screen and that it comes through. Then they can work down to a single app, but it must be in focus to view properly.
