Go to the Applications folder and do a Get Info on iChat (Highlight and use Apple and i keys together.)
In the window that shows up open up the Plug-ins tab.
(those Plug-ins)
I think you are going to have to do this

No video or screen sharing on iChat 4 between identical MBP's and OS

Hi, like many others, i'm experiencing problems with audio/video calls and screen sharing on iChat 4.
It's really important since my dad lives abroad and is 80 years old, so i need to help him out by taking over control of his MacBookPro when he needs me to.
Here's our setup when it DID work:
We were both in my house, on my network, through my Airport Exreme. We're both running 2009 MacBook Pro's with OSX 10.5.8 on it, and were signed in to iChat through our google account (jabber).
Then he returned back to his home (i'm in Holland, he's in Austria), and since then we can only do text chats on iChat. Whenever we invite eachother for video chat or screen sharing, we get the same error message about a communication error, or telling us the other one 'didn't reply' or something like that. I'll copy-paste the exact message + error details the next time we try.
We tried to solve it by changing services, meaning i signed in through my @mac.com account and he signing in through his AIM account, but with no luck. Also AIM to AIM didn't help.
I'm still on my Airport Extreme, connected to a DSL modem which is branded by my provider, so no idea what it is.
He is on a Speedtouch ST585 wireless DSL router, which he also got from his provider.
Any settings we should check/change? i've read all sorts of stuff about port forwarding, SIP/NAT compatibility and UPNP but that all works rather confusing than clarifying..
Any suggestions would be highly appreciated.
Thanks,
Lexxy

HI,
Thomson-Alcatel, to give them their Full name, make the Speedtouch Series of Modems
As a Brand they will work with each other no matter if they are a Cable (non routing) modem or a Speedtouch DSL Modem.
So, 2 to 3 (or 3 to 2) will work as they are Alcatels
The computer 1 and computer 2 situation (with said modems) has about a 1 in 5 chance of working based on my personal knowledge of Version 4.3.5 firmware and mush less with later firmware from threads on this board.
The Airport Express does or can do something called Port Mapping Protocol.
It is turned On in the Airport Admin Utility > Internet pane > NAT tab
In some circumstances this can be an issue. (It open ports like UPnP does but in a different way) - IF - the Express in not in Bridge (Off) Mode.
Is the DSL modem you have Routes then the Express should be set to Bridge (Off) Mode so that there is only one DHCP server on your LAN (unless you set the devices to do Static routing)
You could try it without the Express, but I am sure you will get the same results.
Can your Dad reach any of the names in Table 1 http://www.ralphjohns.co.uk/ContactTesters.html ?
(He adds them to his Buddy list and tries Video chats (they Auto Answer) )
There maybe a conflict between the two lots of NAT at your end if the modem and Express are doing DHCP (Share An IP) and your Dad's Alcatel.
It may still be there if it is your modem only and his.
My Personal experience with an Thomson-Alcatel Speedtouch Modem, answering on these boards and doing regular testing with people and work Bosie on this forum which Defcom and I have been involved with - tells me it is the Speedtouch that is the problem.

Screen Sharing in iChat stopped working

To begin with, I have iChat 4.0.3 but I do not see any categories for that version.
The screen sharing feature in iChat was a really great tool that allowed me assist my family from remote locations to help them trouble shoot issues on their Macs. This feature mysteriously stopped working after the release of the 10.5.3 Mac OS X update. Prior to that, the feature worked perfectly and was able to connect each and everytime after all the proper settings were configured correctly at each end. Now, the feature does not work at all in iChat. I have confirmed and I am able to use the screen sharing features in "Back to my Mac" so I can still screen share with my desktop at home when traveling using my laptop, but I cannot screen share trying to connect using iChat. I have double checked the proper settings for sharing and those are good, I have double checked the settings in Quick Time preferences and those are set to 1.5 Mbps T1 as suggested. I have also gone back and applied the 10.5.3 combo update to both my laptop and the iMac that I am trying to connect to. The router settings have all been verified and the ports are open. The firewalls are all set and both allow connections using iChat, File Sharing, and Remote Log In. Still, after all of this, the screen sharing feature in iChat will not connect and results in a timeout error after about 15 seconds. Is this a known bug in 10.5.3 and can I expect some relief in the next update? Are there any other tricks that may be applied? This is a feature I relied on pretty heavily and now it is gone. Thanks in advance for any assistance.
I have read several posts regarding the issue of screen sharing in iChat not working properly and I have tried every solution offered in those threads and none of them have worked for me.

Upon further testing with a different iMac user I was finally able to determine that the problem is router related. I am going to go back again and double check the port settings to make sure they are configured correctly. The router that is giving the problems is a Linksys router and the router that tested fine is an Apple Airport Extreme router. I suspect the LInksys router probably needs to be tweaked further to get it to work properly.

Screen Sharing through iChat over VPN

Does anybody know how to make screen sharing with iChat work over a VPN? It used to work for me but now it only seems to work in one direction. I was testing it earlier today and this is what I saw:
VPN client shares their screen with a machine on the physical local network - OK
VPN client requests the screen of a local machine - Fails with "did not receive data error" after a brief audio-only connection.
Local clients shares their screen with VPN clients - Fails with "dd not receive data"
Local clients requests the screen of a VPN client - Fails with "did not receive data"
The VPN is definitely the culprit, the machines can screen-share fine outside of it, and can curiously screen-share fine with the server on our local network when they are VPN'ed in, just not with each other. The server is running 10.5.4.
Anybody have any experience in making this work?

Livebox devices tend to be actually made by Sagem
See this list http://portforward.com/routers.htm
IS the model you have listed ?
It may help if the ports are opened by UPnP as Screen Sharing tends to use more random ports that basic Video/Audio chats.

Remove little window "my computer" screen when screen sharing with iChat?

Anyone know if it is possible to remove or minimize the little window when screen sharing with iChat? if you try to drag it off the screen, it just pops back. It does not seem possible to close it without getting booted out of the screen sharing.

As the "little Screen" is either your Desktop or the other Desktop depending which you have as the current one you are working in it seems silly to have no access to changing back and forth.
But as you say or rather imply it does sometimes occupy the space you want someone at the other end to see and you can not access that part of the screen or if the other end is trying to show you something it can be hidden my your own desktop.
AT present Not Even Chax does what you want.

IChat screen sharing - switch computer keyboard shortcut? Help please.

When I am screen sharing with a person in order to switch to my computer I must move my mouse and click the window in the bottom left...when doing so I interrupt something someone is doing on their computer...is there a keyboard shortcut to switch between the two computers without moving your mouse?

Ok, I just found out how to do this. It isn't an official solution, but it works quite well.
Simply press the power button. You will then regain control of your mouse. Hit command-tab or use the dock to switch apps. Do not click cancel until you've switched apps, or you'll be thrown back into the screen sharing. Once you're out of iChat, you can do whatever you need to do. The Mac you were sharing with will remain in the background above your desktop, so you can keep an eye on it. When you need to get back in control of the action, just click into the other Mac's screen, which is effectively an iChat window. iChat will return to the foreground, and you'll be back where you started. Good luck, and enjoy!

Screen sharing in ichat 4 works on my MacBook Pro and does'nt work on imac

I am outside the US and Canada and I have a MacBook Pro and 3 imacs, 2 at my office and 1 at home. I used to use screen sharing among all of them but suddenly the imac at home does not allow sharing its screen, it only can share screens on other units, the (share my screen with...) command is faded but all other ichat features like video, speech and text are fine.
I reinstalled ichat again thinking that it could be corrupted but it is still the same.
I don't have a network or a firewall problem because when I use the same wireless network at home and login with my MacBook, the MacBook works perfectly.
I matched the settings of all units but still no progress.
I need help to restore that feature again.

If this happensd in the future go to USers/(your account)/Library/Preferences.
Delete com.apple.ichat.plist and restart iChat
If that does not work delete com.apple.ichatAgent.plists and restart iChat
It will be one or the other most likely the second.
Deleting them one at a time with a restart will pin point which one it is.

No Video or Screen sharing in iChat since last update.

I recently purchased a new MacBook Pro 15.4" laptop.
When I first started up, iChat worked beautifully. But after I installed the series of updates, I chat will not send or receive video, and will not allow screen sharing. It's telling me that there's no response from whoever I am trying to connect with. I've tried with three other Mac users, and no luck.
Has anyone else had this problem? Is there a fix for this?

Screen Sharing in iChat not working

iChat under Leopard seems to work fine, I got everything running including video chats and theatre but screen sharing (which works via Finder locally without problem) does not work. I cannot get to see any screen of my iChat partner while he gets a inital 'screenshot' which is not updating, nothing else.
It cannot be a firewall issue as both Macs have been moved to the firewall DMZ and Leopard Firewall is off.
Any ideas?

Hi,
Since the earlier post I have managed to Screen Share.
I did put the Mac Firewall On.
It was then as simple as using the item in the iChat Buddies menu (The option to allow sharing has to be On in the Video menu)
It replaced the Video I was having and does not go back to the Video when the Keystroke of Control+ESC is used and the Video chat has to be re-established.
I do not have Encryption.

Screen sharing via iChat

Not really a server question I know, but I wondered if anyone was experimenting with iChat screen sharing as a support tool. Most of my customers are set up for iChat using my own server and IM me with questions from time to time. I've just started installing Leopard on a few clients and wanted to try out the screen sharing. My own machine is a 17 inch Powerbook and it is looking as if there's a limit to the desktop size of the remote machine. Trying it with this particular client's machine, which is a 15 inch Macbook Pro with an attached 20 inch Cinema display, iChat screen sharing never finishes initialising. But if I reduce the resolution of the Cinema display from its default to, say, 1344x840 it works - and shows both remote screens (the Macbook display and the Cinema display).
Am I discovering that it'll only work where there are no displays connected to the remote system that have a higher resolution than the local one(s), or is there a glitch here that can be fixed? Given that it just 'hangs' I'm tempted to think it's a glitch and not some designed-in limit.

...should have mentioned - the connection is jabber of course, the server is 10.4.11 and both machines are 10.5.1 with 2Gb RAM.

Error Using Screen Sharing (Not iChat)

I have a PowerBook and a G4 tower, both 10.5.6 and when I am using screen sharing I get an error: "Connection Failed to "********" Please make sure that Screen Sharing (in the Sharing Preferences section of System Preferences) is enabled on the computer you're connecting to...). This worked at one time. Sharing is enabled on both computers, the firewall has been turned off. Still it will not connect. Anyone have any ideas?

If you see: Apple Remote Desktop in the Services list in the the Sharing pane, select it. Also, you might need to assign permissions.
Setting permissions for screen sharing
Use the Sharing pane of System Preferences on the computer you want to share to set up screen sharing accounts and assign permissions to them.
To set up screen sharing accounts and permissions:
On the computer you want to control, choose Apple > System Preferences, and then click Sharing.
Select the Screen Sharing checkbox.
Select “All users” or “Only these users,” depending on who will be allowed to share this computer.
If you select “Only these users,” click Add + and select Sharing Users, Network Users, or Address Book from the list, and then choose a user. Or click New Person and assign a name and password to create a new sharing user.
Click Computer Settings and select to allow anyone to request permission to control the screen of this computer, or to allow Virtual Network Computing (VNC) users to access the screen after entering a password.

Screen Sharing in iChat / iMessage - not on PC?

So my question is how are we able to do screen share with iChat / iMessage using the google talk servers as I don't think Windows users can use this feature using a chat client - is it just tying it VNC or somthing in OSx?
(I've just figured out how to add the share screen feature back to iMessage (buddies list view) after it was removed. Hint - add agoogle talk user in iMessage preferences then hit command-1 and you will see the screen share option at the bottom of the buddy list.)

Hi,
The Screen Share feature is Buddy to Buddy (AIM to AIM or Jabber to Jabber) when the Buddy is using either iChat (4 and Above) or Messages in Mountain Lion.
You cannot do it to PCs.
You cannot do it to Jabber Accounts such as Google IDs when they are logged in via a web Browser.
In Messages you have to add an Non iMessage Account to have Buddy List.
This adds a "Buddies" item to the Window Menu of Messages.
In the General Section of the Messages Preferences is an items that refers to gathering the accounts into one List. Unticking this will separate out AIM, Bonjour, Jabber/Google and Yahoo Accounts in to separate Buddy lists.
Yahoo Accounts cannot Screen Share as they are Text Only.
Bonjour accounts can Screen Share as they can Video and Audio Only chat.
The process involves invoking the Apple Remote Desktop engine along side an standard Audio Only chat in iChat or Messages.
The Apple Remote Desktop bit is a VNC connection on a random port.
For this reason it is best to use UPnP on most routers or Port Mapping Protocol in Apple Base Stations.

Screen sharing from iChat with Mountain Lion

I have not upgraded yet. I want to, but I am concerned that I will no longer have the ability to screen shard with my parents out of state.
I utilize iChat to control my parents computer, they live out of state and are not too computer savvy, this has been a life saver for me. Does Mountain Lion have a feature like this or is it gone with iChat? Is there a video chat option, or am I stuck with facetime???

Hi,
Yes.
You have to use the same iChat ID as you do now. (AIM or Jabber based)
You have to (it's just easier) have the Buddy lists on View (by default they are not)
Yahoo was added for iChat 6 and is in Messages but does not do A/V chats
iMessage (the new Apple Services between Apple iOS devices and Macs with Mountain Lion) is also Text only.
You have to be able to do A/V Chats.
Speed-wise over the Internet this has to at least 128kbps (the same as a Video Chat on a 1-1 basis)
Another way to view this is that Messages is iChat with the iMessages ability shoehorned in and with a main interface change.
When you first start up Messages it tends to push you to enter an Apple ID to "register it" for the iMessage service.
If you migrate an older OS's User Account to the computer the System Preferences > Mail, Contacts and Calendars (New Preference Pane) picks up on email and other IDs which tends to mean they get added to Messages for you.
You can of course add Screen Names and IDs using the + Button in Messages menu > Preferences Accounts like you do in iChat.
This tends to mean the Messages Menu > Preferences > Accounts looks very familiar
The Window Menu can look a little different.
CMD + 0 brings up the Messages main window (A Chat Window that does tabbed Chats and an Interface all rolled into one)
Once you have other non iMessages Accounts then CMD + 1 brings up Buddies (A combined Buddy List). It is not listed until they are logged in.
They can be unlinked in the General Section of the Preferences at the "Gather all Accounts into one List" line.
Your "desktop" can then look like iChat used to:-

Ichat Screen Sharing will not work no matter what I try...

I have read all the forums and can't find an answer. Something that should be so simple such as screen sharing through iChat (as advertised) is virtually impossible. This I can not explain. Especially since video chat works!
Both computers in question here are macbooks, both have leopard, both are or wireless networks. Is the router blocking the connection and if so, why will it allow video chat but not screen sharing?
There is either something real simple that I am missing here, or this is not possible at all.
some things that i have tried:
disabling stealth mode
on the firewall, enabling incoming traffic from ichat
made sure screen sharing is enabled in ichat
made sure the settings were the same on the remote apple computer
tried unchecking everything in the sys pref "sharing"
Both of the parties involved are using the same ISP, this really is mind boggling.
Is this a bug that is being fixed or what? I am not trying to perform a miracle here, but this is getting ridiculous.
If this is a router issue, apple should release some documentation on how to configure ichat screen sharing through your router.
If anyone has had this problem and has a fix, I would love to hear it. Keep in mind I have googled this many times and tried just about every piece of advice that I could find on this.
Thanks

iChat Screen sharing does not as such for the screen bit use the Video/Audio port.
The Documentation was lacking last time I looked.
This one tells you the port changes in Leopard http://docs.info.apple.com/article.html?artnum=306688 compared to Tiger
Tiger is linked in the first to here http://docs.info.apple.com/article.html?artnum=93208 where most of the other ports are.
However Screen sharing was not part of iChat 3.
If you do a Quick Look at the .plist(s) you will see the reference to ARD which is Apple Remote Desktop which is what the screen ending part is based on.
This Doc will tell you which ports ARD is likely to use
http://docs.info.apple.com/article.html?artnum=106439
(It says 5900 and 5988)
This should be allowed through the use of UPnP in your routing device or specifically opened.
Now the not so good news.
I run Little Snitch, A utility that tells you ports and IPs of incoming and outgoing network connections by any app you have.
This has told me that in fact the Screen port seems almost completely random normally in the 50000 range of ports
It may not be all you wnat to hear but I hope it helps.

IChat screen sharing does not work on my Mac Pro

I have a weird iChat screen sharing problem that i can't seem to resolve on my Mac Pro. Ever since i got my Mac Pro in early 2008, using the screen sharing feature in iChat has always been flaky. I have never gotten to the point of getting it consistently working. Lately, i have not been able to get it to work at all.
Most of the time, when i choose to share my chat target's screen (or when i share my screen), i would be able to see my chat target's screen and use the mouse for several seconds before the shared screen session is ended. The errors that i am getting are:
+"Disconnected from Screen Sharing because:+
+No data has been received for the last 10 s..."+
+"There was a communication error during your chat.+
+No data has been received for the last 10 seconds. You can send+
+details about this problem to Apple to help improve future versions of+
iChat."
On other occasions (mostly when i am trying to troubleshoot this issue by testing in the same network with my Powerbook, which is on 10.5.6 as well), i get this error:
+"Disconnected from Screen Sharing because:+
+Screen sharing could not be established."+
I have tried to do screen sharing via iChat with other Macs in the same network and also on the internet but with the same problems.
Initially, i thought this may be router related. But the fact that iChat screen sharing on my Powerbook works perfectly both in intranet and internet eliminates my router as the culprit.
I have also tried disabling the OSX Firewall but the outcome was the same.
I read some posts that there may be issue with using the external iSight web cam. I unplugged it, cleaning up all the iChat-related caches and preferences and tried again but with the same result.
I have also tried connecting to iChat using several different account types (mobileme, .mac and AIM) but the end result is the same.
I run a Ubuntu VMWare fusion VM on my Mac Pro as my webserver. I thought that may be the problem. Shutting down the Ubuntu VM also does not help.
Applecare support personnel also instructed me to re-install iChat but that did not help as well.
One interesting error i noticed in the system.log (seen via the Console app) that is generated everytime iChat screen sharing fails on my Mac Pro:
+12/23/08 12:32:00 AM /Applications/iChat.app/Contents/MacOS/iChat[507] error getting server version+
I am really running out of ideas on what else i can do to get this resolved.
Thanks in advance for any suggestion.

The audio and video chat portions of iChat work fine.

I managed to make some headway in my attempts to troubleshoot this problem. I did a fresh Leopard install on one of the drives in my Mac Pro. I then proceeded to update it to 10.5.6. After that, i launched iChat and attempted screen sharing with my Powerbook. The first few attempts failed, with the following symptoms:
- i would be able to see and control the Powerbook's screen
- after 5 seconds, my screen sharing session is disconnected
I then unplugged my external iSight. After i relaunched iChat, i managed do screen sharing in iChat without being disconnected!!! When i connected the iSight back into the ACD, with iSight off, i attempted to screen share again. This time, it failed after about 5 seconds, just like earlier. I then turned iSight on. This time round, the screen sharing session was not disconnected!!
So in addition to the iSight issue, something in my original Leopard startup disk is causing iChat screen sharing to fail because even when screen sharing was failing on my fresh Leopard install, i do not see this error:
/Applications/iChat.app/Contents/MacOS/iChat(507) error getting server version
So if i can figure out what is causing this error to show up in system.log, then i can manage the iSight issue.
