Screen sharing is not listed in system prefernces?

hi, I am trying to setup screen sharing so I can use my computer from iPod with vnc,
I know I need to enable screen sharing from system prefs. But it wont give the option.
this is what's listed:
personal file sharing
windows sharing
personal web sharing
remote login
FTP access
apple remote desktop
printer sharing
xgrid.
but not screen sharing

No BDAqua, Remote Login is for ssh, screen sharing is another name for VNC, and to start the built in Tiger VNC server enable Apple Remote Desktop, check out the "Access Privileges" screen and tick at least one user and the "VNC viewers may control screen with password" option choosing a strong password. You may then have to do some port forwarding/firewall configuration depending on your setup. There is also a free highly regarded VNC server called Vine Server which gives you more options, and is IMHO less buggy. Be aware however that VNC is inherently insecure unless you do it via an ssh tunnel.

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.

IChat 4.0.7 Screen Sharing does not work.

Me and my friend both have identical machines, the intel iMac 20" 2.66mhz
Software is identical
iChat version is identical (4.0.7 (616))
Video Chat works perfectly, our internet connections are fantastic, no issues there.
Both using Netgear routers with uPnP enabled.
Internet Sharing is OFF
Firewall is "set access for specific services and applications" and iChat and iChat Agent are added.
I conclude that Screen Sharing *does NOT work* as advertised.
Apple, I am most disappointed, get it sorted for next release please.
Who else has witnessed this epic failure?
Thanks,
edit
Also, what is this iChat AV nonsense? Where are the iChat 4 forums?

Thanks again Leo for your help,
Yes I was refering to the screen sharing in system preferences/sharing.
Checked the video menu:
Screen sharing enabled
Camera enabled
microphone enabled
so no that's not it! Was hoping it was something simple like that too.
Both netgear routers dont have any ports forwarded, just upnp enabled.
The frustrating thing is, both macs are new, one is only days old, and neither mac has had it's setting messed about with or anything.
It would be great to find the solution, 100's of people having similar issues if you google it.
*edit*
Just a thought, would the type of account make a difference? At the moment we are both using the type of accounts that iChat creates when you select "get an iChat account" (creates a [email protected] login)

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.

Removing an account not listed in System Preferences Accounts?

Somehow I inadvertently created a second account on my iMac that shows as an option at startup. I think I did this with the startup disc somehow. It's not listed in System Preferences>Accounts. How do I get rid of it?

I tried the terminal command first. It returned this line:
dsebableroot: Command not found.
I then tried the instructions after the link http://support.apple.com/kb/HT1528?viewlocale=en_US
"Click the Finder icon in the Dock.
From the Go menu, choose Utilities.
Open Directory Utility.
Click the lock in the Directory Utility window.
Enter an administrator account name and password, then click OK.
Choose Disable Root User from the Edit menu."
However in the Edit menu, "Disable Root User" is not an option. "Enable Root User" is.

Hi,
I am presuming you are looking in the Video Menu but are finding you do not have "permission" to enable Screen Sharing.
In Messages Menu > Preferences > Video section what speed setting is set in the Bandwidth Limit drop down ?
It should be no lower that 200kbps if you want to Video chat or Screen Share (the Min for both is 128kbps)
Even if it shows a speeds higher than this change it to something like 500kbps then close/Quit Messages and then restart it. (i.e change the setting anyway to give a bot of a jolt)

Screen Sharing does not accept my password anymore

Hi
I have a headless Mac Mini Server running Snow Leopard Server 10.6.8 and a MacBook Pro running Snow Leopard 10.6.8. I detected this morning, that I'm not able to connect from the MacBook Pro to my Mac Mini over Screen Sharing. All other services, mail server, iCal server, Address Book server, file sharing over SMB or AFP even connecting over VNC do work.
- I select the Mac Mini symbol in Finder
- in column view, I select Share Screen...
- in the connection dialog, I add the password (username is already predefined)
- on connect, I get: Authentication failed to "servername". Please verify you have entered the correct name and password.
I use the same username and password with Server Admin, or logging in locally over VNC so I know this is correct.I'm sure I did not change any settings concerning screen sharing (I did some experiments with WebDAV recently)
I'm not sure, when I used Screen Sharing the last time, is there a log on the server for this? Could be, the problem was introduced with 10.6.8, but I'm not sure. From the logs I see, Screen Sharing did work on July, 16th. This would narrow it down to: iTunes 10.4 (not likely), Migration Assistant Update for Mac OS X SL 1.0, and Remote Desktop Client Update 3.5.1.
On the server, I found the following log entries: Jul 21 20:24:33 servername AppleVNCServer[1362]: no such user: user@LKDC:SHA1.xxxxxx: 2
Any help on this problem?

Sorry if that didn't come out right. I should have taken the time to get the correct labels off of the user preferences dialogue and it would have made more sense.
When you create a new user, there are two fields: one for "Full Name" (typically the user's actual name) and another for "Account name" (this usually a more Unix-like user-id). On my system, typing "John Doe" into the Full Name box automatically populates "johndoe" into the Account Name box. I would guess the majority of Mac users will leave that default in there, type in a password and hint and complete creating the account.
Interestingly, you cannot view the Account name in the user preferences dialogue once the account is created. However, the Account name is used as the name of your Home folder.
In the past, I've used that Account name when connecting to shares in finder. I just verified that when you open finder and click "Connect As" and choose "Registered User," the authentication prompt in SL automatically has the Account name in the user field. Once connected in finder, all I had to do is click Screen Sharing and it would just open up. Presumably since I had already authenticated via finder. After the last updates, I started getting a password prompt only when attempting to start screen sharing. Finder still worked the same as before, and I was able to view all my folders. Using the Full Name instead of the Account name got me through the second password prompt and opened the screen sharing session.
I tried authenticating the finder with the Full Name instead, and still got the second authentication prompt when launching screen sharing. Clearly Apple has made a change to screen sharing that no longer passes through your finder authentication.
If you've somehow already been using the Full Name, and not the Account name, to authenticate in finder, this fix doesn't help you.
What I meant by "feeling stupid" is going to great lengths to step through a lot of troublesome reboots and whatnot, only to discover that the problem is an arcane, and apparently pointless change with which user name on the account authenticates for two apparently related features (you do go through finder to get to screen sharing!). I certainly didn't mean you were stupid. I wouldn't blame you for having to figure out something Apple changed up after years for no apparent reason. I wasn't real happy about it either after wasting an hour or so figuring it out. My poor choice of words was really meant in the spirit of that "d'oh!" moment when you find the trivial 5 second fix after spending that hour (or days) doing lots of potentially risky stuff to no avail.

IChat Screen Sharing will not work when VNC will?

I am finding it impossible to get Screen Sharing working via iChat. I'm not surprised, as iChat seems extraordinarily balky at doing anything other than text chat. However, what confuses me most about this is that the Connection Doctor 'Capabilities' tab suggests that the net connection for my family members (1024/128) is "too slow" for Screen Sharing - yet I have been using OSX VNC for two years perfectly successfully to do so?
Does using Screen Sharing directly have the same limitations?

Hi,
In System Preferences > Quicktime > Streaming change the Speed to 1.5Mbps
This should change what iChat sees as being Capable off once you restart iChat.
The VNC app Screen Sharing that Opens form the Finder > Go > Go to Server VNC:// does not include a Audio component.
This uses less bandwidth than the iChat Screen Sharing which does include an Audio stream.
Also the Screen Sharing is done on a separate port to the Audio part and from testing seems to be a random choice.
For this reason we have been suggesting using UPnP in any modem or router to allow ports.
Apple have not said what ports it uses
http://support.apple.com/kb/HT1507?viewlocale=en_US Tiger A/V ports and Bonjour and Jabber
http://support.apple.com/kb/HT2282?viewlocale=en_US Leopard A/V ports (It should say but does not that you still need the Jabber and Bonjour ones if using them).
This doc http://support.apple.com/kb/HT2020?viewlocale=en_US says you need iChat to see at least a connection speed of 128K UP and Down for Screen Sharing.
It is known that iChat Screen Sharing is based on Apple Remote Desktop but it does not use the same ports (5900 and 5988).

FTP sharing service not listed under sharing preferenecs

Hi All,
I need to enable FTP sharing on my MacBook Air (2011 OSX 10.7.2) but when I go to the Sharing settings under system preferences, FTP is not listed so I can't turn it on. Any thoughts as to how I install the FTP service?
Thanks!

I know how to enable it, it's just a stunningly bad idea. What are you doing that couldn't be done better with SFTP in 2012?
There's a reason Apple no longer exposes a GUI control for it.
But here:
sudo -s launchctl load -w /System/Library/LaunchDaemons/ftp.plist
Replace 'load' with 'unload' to turn it off again.

Screen sharing is not working at login screen

Hi:
I need a little help. I have a headless Mac (System A) that I just upgraded to Mountain Lion (not Mountain Lion Server) from Snow Leopard Server.
From another Mac (System B) running Mountain Lion I was previously able to use Screen Sharing to remotely acess System A's login screen. Now, after upgrading from SL Server to ML I can only use Screen Sharing to remotely control System A from System B AFTER I have already logged into System A using a direct attached keyboard and screen. In other words, I lost the ability to access the login screen on Sys A.
Anyone have any ideas here???

I was having the same issue. In my case, I had copied /System/Library/CoreServices/Screen Sharing.app to the /Applications folder, some time ago. I did this so I could more easily launch Screen Sharing via Spotlight. Because of this, when I launched Screen Sharing, I was executing the 'old' Screen Sharing app. I re-copied the 'new' app to /Applications, and all is well! Hope this helps!

L3 Cache disabled, non-functional or not listed in system profiler?

I have a 15" 1 ghz powerbook G4 titanium, and for as long as I can remember, the 1 MB L3 Cache it's supposed to have is not listed in the system profiler. It fails the power-on self test in OS 9, as well as the Apple Hardware test CD. IS there any way of investigating this? The machine seems to run okay, but i'm sure it's hindering the performance of it somehow...

Hi Les,
Welcome to Apple Discussions.
As far as "investigating" goes, you've done all you need to; three separate sources all indicating the same L3 failure is pretty solid evidence.
I'm sure you're correct that it affects performance; unfortunately, cache is soldered onto the logic board, so beyond replacing the logic board, there's nothing you can do. If you've lived with it this long, I'd continue to live with it and put the LB replacement money toward your next machine.

Hi,

Warning SYSTEM's UDP port 445 is not open or listening.
Based on your description, I’m a little confused with this issue. Please run following commands with administrator
permission and monitor the result. Would you please check and confirm whether any process listened the UDP port 445?
netstat –ab
netstat -a | find /i "445"
In addition, I noticed that you use Syshelp (Symantec validation tool) to check. I suggest that you would post
the warning message in Symantec Forum and confirm this issue. I believe we will get a better assistance there.
If anything I misunderstand, please don’t hesitate to let me know.
Hope this helps.

Why are applications not listed in System Profiler?

Hi Apple Support Community,
System Profiler -> Software -> Applications displays "No information found." instead of the expected list of 64bit / 32bit applications installed. What could cause this and how can I get System Profiler to rescan the applications installed?
Thank you,

Discussion thread http://discussions.apple.com/message.jspa?messageID=11077939 suggests Applications are not displayed in System Profiler because I purposefully disabled Spotlight for performance reasons and the indexing of external drives.

Screen Sharing Suddenly Not working?

I've been using Screen Sharing for months now to control my Mac Pro Desktop that is connected to my Plasma TV with my Macbook Pro laptop with no issues. Suddenly now a message pops up everytime I try to connect telling me that the connection doesnt support encryption and the video stutters (advances every few frames at a time). Anyone know how to fix this issue?
Thanks!

I failed to mention in my previous post that my work computer is showing up on my network.
