    Please try to clear the following app cache then check whether fix this issue:
    1. Clear the Skype for Business cache:
    a. Log out and quit Skype for Business.
    b. Go to Finder> press Command+Shift+G> type in /users/<MacUsername>/library > delete the following files: 
    Containters > com.microsoft.SkypeForBusiness
    Internet Plug-Ins > MeetingJoinPlugin.plugin
    Logs > LwaTracing
    Saved Application State > com.microsoft.SkypeForBusiness.savedState
    Preferences > com.microsoft.skypeforbusiness.plugin.plist

    2. Clear the Keychain access: Open Keychain Access from /Applications/Utilities folder. Delete all keychains starting with Skype for Business.

  • Thanks, but that didn't work for me. Apple introduced a few breaking changes in macOS Catalina, like to stop 32-bit support and SHA-1, I assume one of that is used during screen sharing, and my Skype crashed because of that, please see the attached log for more details.

  • Hi martinxd,

    Could you please uninstall the SFB clinet in your Mac, and reinstall the client from the following link: Skype for Business on Mac. Please try to use the latest version of SFB client then check again.

    In addition, you could also check with Apple about the function.

  • Sadly not, I'm still experiencing this issue.

  • Hi Evan

    that also didn't fix the problem, as I said, Apple did a few breaking changes like not supporting 32-bit applications anymore and blocking SHA-1, I assume when someone shares his/her screen either a 32-bit library or SHA-1 is somehow used.

  • Yes, this is not an install issue, is happening for others too.

    I am sure we all understand this is a pre-release version of MacOS, myself I just want to ensure the Skype team is aware.

  • I’m having the same issue too. Every time someone is starting the screen sharing, the sfb crashes... Using the latest release of the sfb.

  • I'm having the same issue. SFB is crashing when adding someone on an audio or when there is a screen shared via SFB

  • This occurs because Skype for Business does not have Screen Recording permission.

    1. Close Skype for Business
    2. Reset the TCC for Skype for Business with the following command from a terminal:
      • tccutil reset All com.microsoft.SkypeForBusiness
      • Response: successfully reset All approval status for com.microsoft.SkypeForBusiness
    3. Open macoS Preferences and navigate to Security & Privacy -> Privacy
    4. Select Screen Recording from the list on the left. Note that Skype for Business is not listed.
    5. Open Skype for Business (It should open normally) If any permission dialogues appear, permit it.
    6. Initiate a screen sharing session with another party. 
      • This will cause the Popup to appear asking for permission to record the screen.
      • Select the Preferences button. 
      • This populates the view with Skype for Business
    7. Click the check box to permit Screen Recording
    8. Done

    Do the same for the video camera as well by using the camera and granting it permission.

  • tried the above steps to grant skype permission but the second someone shares their screen it crashes.  It prompted for camera and mic during the initial call but I did not get a prompt to grant permission for screen recording.

  • That didn't work for me.

    It didn't even ask for permissions on anything (SfB doesn't show up in any of the privacy sections).

  • This does not work. 

    Also the tccutil command returns:

    tccutil: No such bundle identifier "com.microsoft.SkypeForBusiness": The operation couldn’t be completed. (OSStatus error -10814.

  • I can't even send Chat messages using SFB, just crashes out.  Tried all the steps above.  Hurry up Microsoft!
