Follow these quick tips if you cannot share your Mac’s screen with others

• If you are not the meeting host, confirm with the host that meeting participants can screen share
• Close all other programs that may use your camera or microphone
• Connect to the fastest internet connection available–if you have 5 GHz, use that instead of 2.5 GHz
• Try maximizing the app’s window on your Mac and then choose the button/option to screen your share. Or, if on full-screen, reduce the size of the app window and then try to share your screen
• Try using the web version of the conference service using Safari, Chrome, or another third-party browser INSTEAD of the Mac app
• If using a VPN, try temporarily disconnecting from the VPN during the call
• Check for a macOS software update (especially any security updates) and update your Mac if needed (be sure to backup first, before updating)
• Temporarily turn off any sleep and power nap settings using Energy Saver preferences. Go to Apple menu > System Preferences > Energy Saver
• Restart by going to Apple menu > Restart
• Check the Mac App Store or the web conference downloads site for any updates to your web conference apps
• Quit the app and relaunch it or if necessary, force quit the app and relaunch it
• Delete (uninstall) the conference app and reinstall it using the latest version available
