Webex Screen Share Not Working on Mac

Symptoms

The Share button is greyed out, Webex keeps asking for access, or others see only your wallpaper or a black screen.

Why it happens

• Webex lacks macOS Screen Recording permission
• Permission granted but Webex not restarted
• Sharing a minimized or closed app window
• Old Cisco Webex Meetings app still installed alongside the Webex App

How to fix it

Try these in order — the most common fix is first.

1. 1. Grant Screen Recording permission

   1. Click the Apple menu > System Settings
   2. Open Privacy & Security > Screen Recording (Screen & System Audio Recording on newer macOS)
   3. Turn on Webex and Cisco Webex Meetings if listed

2. 2. Fully quit and reopen Webex

   1. Press Cmd+Q in Webex (closing the window doesn't quit it)
   2. Reopen Webex and rejoin the meeting

3. 3. Also allow Accessibility and Microphone

   1. In Privacy & Security, open Accessibility and turn on Webex
   2. Open Microphone and turn on Webex

4. 4. Share the entire screen

   1. Click Share and choose your whole screen instead of one app window
   2. If you must share a window, make sure it's not minimized

5. 5. Update Webex

   1. Click your profile picture > Check for updates
   2. Install the update and retest
