Q: Screen sharing w/ Yosemite not working

Hi all,

 

I am trying to do Screen sharing from Yosemite MBP to Yosemite MBP and it will not let us. We are both logged in and texting etc. but even when we ask the person to share their screen and they say allow - nothing happens....

 

It used to work...

Teamviewer works fine...

 

Q: Any way to get this working?

 

Is it a bug?

MacBook Pro, OS X Yosemite (10.10.4)

    Hi, revDAVE.  

     

    Thank you for visiting Apple Support Communities.  

     

    I understand you are attempting to screen share using Yosemite.  Here is a troubleshooting article that may help resolve this issue.  

     

    OS X Yosemite: If you can’t share computer screens

    HI Jason,

     

    You should have access to this I believe Re: Messages and Video Chatting via AIM and Jabber

    It is becoming a bit of a "known issue".

     

    See here Re: I can't video conference or screen share with Messages anymore!

    Another iChat video/screensharing works locally but not over the WAN.

    Yet another iChat/iMessages quit working most of the time a month ago

    There are others if you look.

     

    People need a fix not an outdated Apple Knowledge Doc.

     

    There is also a link in the Doc you link to that refers to Screen Sharing  - but only the method used from the iMessages account - ignoring the method for AIM, Jabber and Bonjour accounts that uses the method that iChat used (And has been there since iChat 4)

     

    The issue is most likely the SNATMAP server which is where every AIM, Jabber and Bonjour chat gets connected through.

    the issue is effecting several OS and therefore iChat and Messages versions including Snow Leopard's iChat 5.0.3 through to Messages 8 in El Capitan beta (that means version 8 in Mavericks, Yosemite and El Capitan as Apple have not changed the numbering).

     

    Any chance you can raise this with higher ups ?

    Yes, What does it take for Apple to take this issue seriously. My kids would really like to see their grandparents on video chat again and I'd like to be able to screen share to help my elderly parents manage their computers. Yes there are other (non Apple ) solutions, but none are as easy and elegant as going through the Messages app that they have been conditioned to use all the time. This is not very Apple like behavior to leave something broken for so long. Please address it ASAP.

    Do the Grandparents have recent Macs, and if so, what about letting the kids and Grandparents video conference using Facetime? Understand it is not the entire solution that you seek.

    They have Facetime, and we can use it, but it doesn't allow for screen sharing and FaceTime rings on all their devices which gets confusing for the older folks. The video chat was perfect and we have been using it since it was added to OS X years ago. Would be nice for Apple to acknowledge the issue and do something about it. Or admit they are removing the functionality. Just ignoring is not very good customer service.

    Hi,

     

    I have had a response from the Hosts in the Thread I started in the Lounge  over two weeks ago.

    It did take another thread by another Poster who has access to that Community to also post and ask the direct question could someone post that they were doing something.

     

    The Host who posted says it has been passed on.

     

    It take this is to the iMessages team, who will hopefully look an the SNATMAP server.

    Yes, Ralph, thanks for integrating these threads.  It is an intermittent issue, and not OS-related, so I think your SNATMAP idea is a reasonable hypothesis (not that I know what that is!).  It seems to malfunction more likely early in the day…I wonder if it's a traffic problem?  At 10 AM eastern time I couldn't do screen sharing, at 3 PM I could…When you think about it, once a lot of people start using screen sharing on Messages, it is a pretty data-intensive thing…and when you suggested going into audio/video preferences and limiting bandwidth to 500 kbps, it seemed like it was more likely to accept a screen sharing request (although not always).

    Hi,

     

    Messages and iChat before it uses a process called SIP (Session Initiation Protocol) to connect two or more people for A/V and Screen Sharing when using AIM, Jabber or Bonjour accounts.

     

    VoIP systems also uses this as does Skype.

     

    Somewhere along the line a server has to connect the two.

    This is very much like an old fashioned Telephone exchange with people.

    It is a text based protocol so it includes instructions and steps such as Ringing, Trying, Inviting and so on.

    More https://en.wikipedia.org/wiki/Session_Initiation_Protocol

     

    Technically there are internationally agreed ports that are supposed to be used.

    On the Internet Back bone and to a certain extent ISPs are supposed ( I stressed supposed) to not interfere with SIP traffic.

    However back during iChat 3 which Added Jabber Buddies to the iChat set up a lot of ISPs world wide started to close the SIP ports and demand extra money to open them up again.

    The regular posters at that time used to suggested that people contacted their ISP for Breach of Contract which solved things for some people.

     

    At iChat 4 Apple moved the SIP function (Skype never seemed to use the ports from the beginning).

     

    The server that does all this stuff for Apple is their SNATMAP server (Originally snapmap.mac.com)

    It is only used by Apple for the A/V chats which includes the Audio Chat alongside Screen Shairng connections in the accounts that iChat can do Video chats for (AIM, Jabber and Bonjour).

    These continue into Messages  but does not included the iMessages variation added in Yosemite.

     

    Once the SNATMAP server has connected the people involved then it drops out of the process.

    As you start up iChat or Messages it is also used to test the Bandwidth speed you have (that is not mitigated by either Older OS and Quicktime settings or the Bandwidth Limit in the app).

     

    This form of chatting is AIM to AIM or Jabber to Jabber or Bonjour to Bonjour.

    You cannot connect across services (not even to the iMessages one in Yosemite).

     

    However as all IDs nowadays tends to be based on email IDs anyone can be added to a Buddy List. (or in the case of iMessages anything can be an Apple ID).

    With the advent of Yosemite's Screen Sharing from within the iMessages account it could mean a lot of unconnectable attempts are being made causing a drain on the server.

     

    The Hosts are now aware (and have posted they have read it and done something with it).

    Now it is a waiting game.

    It will either turn out to be SNATMAP and Apple will do something about (albeit silently) or it will turn out to be something different in which case Apple wil probably lean on the people concerned and we still will not know anything until it all starts working again.

    BTW, this still doesn't work.I tried again a couple days ago ... no news from the higher ups about it? I really miss it and hope this isn't how they just kill it and its not there in future OS versions.

    Hi,

     

    I was able to do some testing a couple of days ago with a Buddy in America.

    It did not work for use.

     

    This info was added to the thread I have with the Hosts.

    Whilst it is customary fro Apple to say nothing in these situations it is also a long time that nothing appears to have happened.

    Normally there would be a silent fix. Or something similar to the info about older Apple IDs (@mac.com and @me.com) not working in older versions of iChat due to improved checks in late iChat 6 and Messages as AIM Screen Names.

    No luck in El Capitan ... though at least the feature wasn't removed, so I guess there is still reason to hold out hope ...

    Hi,

     

    The Thread I have in th lounge is being added to by other Level 6 Posters and above who are also frustrated with this.

     

    This in El Capitan is worry though

    Buddies_Menu.png

    I am chatting to an AIM Buddy but it still only lists FaceTime.  (the Help App says different though)

    You will also note that Screen Sharing is not possible according to this Menu

    A Buddy List show differently
