When you try to share your screen on Chrome on Mac, it is possible the screens will show up as black. This is most likely caused by hardware acceleration. This usually makes a browser faster, but unfortunately can also cause problems.

You will need to disable hardware acceleration for screen sharing to work, here is how.

1. Open Chrome Settings

Press the three dots in the top-right corner of your browser, then click 'settings'.

2. Click Advanced
You'll find the 'Advanced' button at the very bottom of your Chrome settings window, underneath the 'On startup' section,


In the Settings menu, expand the “Advanced” drop-down section found in the left sidebar and then select “System.”

3. Toggle 'Use hardware acceleration when available' off, and press the 'Relaunch' button to apply the changes.

4. Open Kosy, or refresh Kosy and try sharing your screen.

It may also be needed to close Chrome and open it again before the changes take effect.
