I did the standard updates tonight - which included a remote desktop update (to version 3.7 I think) - the in the System -> LIbrary -> CoreServices -> Remote management folder.


After the update (I'm still running Mountain Lion) - screen sharing doesn't work with any of my other Macs in the house.  It basically sits there and never connects - saying "connecting to...." - similiar to what it did a long time ago after the 3.6 updates from 3.5.  Eventually it gives this error... "connection failed to ..."  and "Please make sure that Screen Sharing (in the Sharing section of System Preferences) is enabled on the computer to which you are attempting to connect. Also make sure your network connection is working properly."


I have already tried to restore that folder from time machine to version 3.6.2, as well as restored the file to the older version, but to no avail.  Have already rebooted all the machines, restarted my airport, network hubs, etc.  Tried stopping and restarting sharing already as well.  No go on any option.  Was working just fine before the updates tonight.


Any one else have similar issues and know how to fix?



OS X Mountain Lion (10.8.5), Screen sharing not connecting

    Screen Sharing broke for me too. On 10.8.5 and 10.7.5 computers.

    It appears the firewall has something to do with it.

    When I turn off the Firewall completely, screen sharing works.

    When I manually enable everything in the firewall list, screen sharing fails.

    Is there a hidden app that is not on the firewall list? How can that be?

    Same her fro me ic70. Trun firewall off then all is good. Turn firewall on, even with all connections allowed, and Remote desltop allowed in the options then screen sharing fails

    This only appears to be happening for me on my 10.8.5 (12F45) machine with ARD Version 3.7.  My 10.7.5 (11G63) machine with ARD version 3.7 still works.  I can only connect to the 10.8.5 machine with the firewall disabled.  This sounds like it's a bug that Apple needs to address.

    Yep - same behavior with the firewall.  When I turn off the firewall on the destination machine (the one I want to control remotely), but leave the firewall on the machine I'm using - I can connect to the destination machine.


    I can't remember how to submit a bug request to Apple.  Can someone give me the link to follow?  Thanks.

    Two Macs upgraded to Mavericks and Screen Sharing only works if the firewall is turned off on the target machine.


    This is even with 'Sharing' settings properly set.

    Same for me too, hopefully there will be a fix for this soon

  • Bill Totman Level 1 (0 points)

    I've been in contact with Apple Support and they are looking into it.


    (I did it via a chat session - I also have Apple Care on this machine.)

    Same problem here on a 10.7.5 machine.

    Apple Bug Reporter is here:

    Screen sharing not working on Mac Mini server and iMac after installing Mavericks on both.  As I don´t have a separate screen for the Mini, life suddenly became complicated.  Any ideas or solutions for turning off the firewall on the Mini without logging in (I can access the drive)?

  • merced317 Level 1 (0 points)

    If you can still SSH in to the machine, you should be able to do:


    sudo /usr/libexec/ApplicationFirewall/socketfilterfw --getglobalstate


    That should return:


    Firewall is enabled. (State = 1)


    Then you can run:


    sudo /usr/libexec/ApplicationFirewall/socketfilterfw --setglobalstate off


    That should return:


    Firewall is disabled. (State = 0)


    Now go ahead and connect with ARD.  When you're done connecting with ARD, simply re-enable the firewall with:


    sudo /usr/libexec/ApplicationFirewall/socketfilterfw --setglobalstate on


    Since the connection is already established, you can safely enable the firewall once you've connected with ARD, you don't have to wait until you're done using ARD.  Not the most elegant solution, but at least it's a short term workaround.  If you're fast enough, you've only got to disable your firewall for a few seconds.


    Hope that helps.

    I had the same problem.  I'm running Lion 10.7.5 on the target Mac mini and Mountain Lion 10.8.5 on two other Mac's which were trying to connect to Screen Sharing on the mini. I received the error message as you described. Interestingly, File Sharing worked fine. Only Screen Sharing was broken.


    This is what worked for me:


    1. Go to System Preferences > Sharing and uncheck Screen Sharing and File Sharing


    2. Restart Mac


    3. System Preferences > Sharing and recheck Screen Sharing and File Sharing


    4. Problem solved (for me anyway)


    I hope that works for you.

    Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

    Same here too. Tried some workarounds, but they only work until next reboot :-(
