Aug 29, 2016 2:10 PM in response to Mcfuguby Ralph Johns (UK),Hi,
The Mavericks to Mavericks Screen Sharing using a AIM account (or a Jabber account) was resolved.
At the Yosemite Release it seemed the servers were sorted at the same time.
iMessages in Mavericks does not do Screen Sharing.
However it seems AIM/Jabber Screen Sharing will end in Seirra along with Video and Audio Only chats with those accounts.

Aug 29, 2016 3:18 PM in response to Ralph Johns (UK)by Mcfugu,Thanks for your response, Ralph. Much of what I read about this issue centered on your responses.
I'm sorry, but I'd like to confirm a few things.
1) When you said Mavericks to Mavericks Screen Sharing was resolved, did you mean resolved if one party upgrades to Yosemite or El Capitan?
2) When you said 'iMessages in Mavericks does not do Screen Sharing', did you mean the Mavericks application 'Messages'?
3) Could I ask how you would recommend doing Screen Sharing Mavericks to Mavericks?
(I live in Japan, and occasionally need to help my mom who lives in the States. [She needs consistency rather than new features.] Screen Sharing enables this. It worked fine when her system was Snow Leopard, but I had to upgrade it because the browsers could no longer be updated. I have a 2011 MacBook Air, which I've kept on Mavericks because I'm afraid upgrades will slow it down. But I'm tempted to go to El Capitan, since it seems similar to Mavericks, a mature (tock) OS, rather than a new (tick) bells and whistles OS. But I am tempted by the newer versions of FCP and Garageband which are mission critical for me. Sorry, for all the info.

Aug 29, 2016 7:33 PM in response to Mcfuguby John Galt,Screen Sharing has had a variety of problems with many OS X versions. However, El Capitan finally addressed all of them. Those fixes are fairly recent.
There is no benefit to remaining with Mavericks. To upgrade read below.
Read Upgrade to OS X El Capitan - Apple Support.
Assuming that you are already in the habit of routinely backing up your system you can evaluate El Capitan at no risk and at no cost. If you do not routinely back up your system, you should. Obtain an external USB, FireWire, or Thunderbolt hard disk drive for your Mac, then download and install El Capitan on it. You can choose to start your Mac from that disk or the internal one using Startup Manager (hold an option key while you start your Mac), and evaluate El Capitan at no risk whatsoever to your existing installation. Just be sure to designate the proper installation location for El Capitan when you get to that installation step.
Running OS X from an external USB hard disk won't be as fast as the Mac's internal one, but it will be sufficient to draw conclusions regarding its suitability for your needs.
An external hard disk drive of adequate capacity can be purchased for well under $100 — much less than the cost of some previous OS X upgrades themselves. When you satisfy yourself that El Capitan works for you, then "clone" the external disk's contents to your internal one, and use the external disk for backup purposes — which you ought to be doing anyway.

Aug 30, 2016 12:46 PM in response to Mcfuguby Ralph Johns (UK),Hi,
1) No. I was trying to say that the Server issue (As far AS I could tell) was sorted at the time that Yosemite was released.
2) Mavericks only does Screen Sharing using AIM and Jabber account (well, and Bonjour)
Later versions add the ability to invoke (like FaceTime for Video) the Screen Sharing App on the Mac (It is part of Apple Remote Desktop (ARD) that everyone has.
You can invoke it from the Finder Window to other Macs on your LAN.
Linked to another computer looks like this at the bottom right (iCon for app)
So Yosemite (And Later) can do this in Messages using the iMessages Chat to Start and using the Details option top right.
However Mavericks and Earlier cannot.
Yosemite and El Capitan can actually do both AIM/Jabber and iMessages Screen Sharing.
Sierra will only do the iMessages invocation so to speak.
3) Options
Stay where you are.
Upgrade either to Yosemite or EL Capitan
Add a VPN (Virtual Private Network) and put your Mom's Computer on it and use the Screen Sharing in the pics above.
IN the Finder use the Go Menu > Connect to Server
In the dialogue box you normally connect to another "server" by typing in AFP (Macs) or SMB: //and the IP address of a nearby computer.
You can type VNC:// instead and it will will be a Screen Sharing connection.
If the IP address is the Public IP address of the other end and you have their router set to Forward the Ports to the Computer (so you connect directly) you can do it other the Internet.
See this table TCP and UDP ports used by Apple software products - Apple Support and the listing for port 5900
Of course this requires a bit of tech savy to set up and setting a router via some other Screen Sharing or direction by Phone may put it out of reach.
Messages and iChat obviously do all the hopping through routers and the like for you.
There are other apps out there that will do the same/similar things but I can't say I have tested any.
Re Upgrading.
Mavericks is getting too old in the tooth so to say.
EL Capitan would give you some abilities with regard to Screen Sharing with Snow Leopard.
However with Sierra being so close there is no saying if Apple will close the relevant SNAPMAP server down that handles the AIM and Jabber based Audio Only, Video Chat and Screen Sharing.
We are in no-man's land to some extent.
