    Today's OSX Security update broke the screen sharing function to my Mac mini. It just won't connect anymore.

    These methods of screen sharing no longer work using my MacBook and/or iPhone:
    - Jump Desktop Mac remotely via SSH tunnel
    - Jump Desktop Mac locally
    - Jump Desktop iOS remotely via SSH tunnel
    - Jump Desktop iOS locally
    - Screen Sharing Mac app locally
    - on Mac via the side bar and clicking the 'screen share' option

    The following work:
    - I can SSH to the Mac mini via Terminal on my MacBook
    - I can SFTP to the Mac mini via Forklift on my MacBook (and see the Mac mini's drive just fine)
    - I also see the Mac mini in the sidebar of my MacBook

    Any ideas what could have happened? Any commands I could use in Terminal to get this back up and running?

    Any help much appreciated!

    Ok, back up and running after a Remote Desktop Client installed that appeared AFTER the security update. Ugh.

    Thanks for mentioning the remote desktop update that shows up after! I've had remote hands helping me all day on this and didn't even think to have them check for more updates.

    Still having some trouble with mine. What are you Sharing preferences in SysPrefs?

    Fixed via solution on Apple forums: I've just managed to get back in by disabling the Remote Management and Screen Sharing under the Sharing Preference Pane. I removed all of the users allowed to connect and then rebooted. When I logged back in I tried turning Screen Sharing back on first for the Admin account. I managed to connect via Screen Sharing and then turned on Remote Management (remotely) and added the Admin account there as well. To test this I closed the Screen Sharing window and connected again.
