Why do I need to start up Screen Sharing twice to get it to work ?

I have an Intel Mac Mini connected to my TV, so I started using Screen Sharing from my MacBook Pro to be able to work on it when others were watching TV.
Both Macs used to have OSX 10.5 Leopard, and everything worked fine.
Now they both have OSX 10.6 Snow Leopard, and whenever I startup Screen Sharing, the connection-windows asking for my Name & Password comes up properly, but then it hangs... it stays in "Connecting..." for ever (litteraly).
I'm not able to quit or force-quit the connection-window by then, so it stays in view...
(Screen Sharing isn't even listed in the force-quit list as a running app)
but...
when I just try Screen Sharing again, I get connection immediately and it seems to work flawlessly...
...it's just that the connection-window is impossible to quit...
it stays in view an is really annoying...
this looks really crappy...
can anyone tell me why I do need to startup Screen Sharing twice to get it to work ?
Is this a bug ?
(If so : please apple fix this a.s.a.p.)
...or am I doing something wrong ?
(if so : what am I doing wrong ? and how can I get rid of this annoying screen ?)
Thank you for your kind reply.
Toon.B

it's October and this really annoying problem still exists !
the unnamed screensharing-loginwindow keeps "Connecting...", and I'm unable to shut it down...
...even after my screen sharing session is over
...even force-quitting is impossible (this 'app' just isn't showing up in the force-quit-window...)
please Apple - fix this ; under 10.5 it was working great !
Does anyone have any idea how to fix this ?
(besides restarting my Mac)
Thanks !

How do I get started with screen sharing?

There are dozens of articles on the web and posts here talking about what's new with screen sharing in Lion, but for the life of me I can't find anything that tells somebody completely new to screen sharing how to get started. If I want to do screen sharing with a friend (over the Internet, not a LAN), what exactly do we have to do to get started?
Sorry for a noob question, but everything I see assumes you're already completely familiar with it and just want to see Lion tweaks.

ok so go to your system preferences on your MAC > go to sharing > click the screen sharing option on> next go to the add users section right below on the right and you add your friend whom you want to share with. You have to select a password for this person. When you get this done you will see a
Other users can access your computer's screen at:
and you will have an address there with some numbers. give this to your friend whom you want to see your screen, they have to post this in their web-browser, and that is how you remotely screen share. This is if you all are not on the same network. Also if you want to share his/her screen they will have to do these steps for you.

Screen sharing and remote management no longer working after some uptime

Server is withoiut monitor.
Users need to login via screen sharing from time to time.
"Enable screen sharing and remote management" is ticked in Server.app everything is working fine (for days, weeks).
ARD reports "Screen Sharing Available", so remote management is not running how it should.
Screen Sharing.app is "Connecting…" forever.
Kickstarting ARD (http://support.apple.com/kb/HT2370) does not help.
Restart fixes it.
Is there a workaround (over ssh) or a fix?

Off-hand, no. I don't. See this posting, or as would be typical in any case, try it?

Screen Sharing, audio, and video chat not working with certain people

My ichat application will suddenly stop working after just a few seconds of starting wither screen sharing, video chat, or audio chat. I get the error message "No data has been received for the last 10 seconds." How do i go about fixing this?

Hi,
This message can be caused two ways.
1) a loss of Internet Connection through a Physical means.
(turning Off Airport card, Pulling out Ethernet Cable, modem or router failure, loss of service from ISP)
2) A router or modem Software intervention.
This most commonly happens in Video chats. The device has a feature called DOS (Denial of Service) which with modern Internet Speeds and Video Streams gets to the threshold where it cuts in. It requires that you turn the feature Off as there is not adjustment in the threshold at which it works.
A similar feature with a similar result is SPI (Stateful Packet Inspection).
Having said that, it very unusual to have it effect Audio only chat or Screen Sharing.
This means the issue could be at the Buddies end.
NOTES:
iChat creates Logs of Connection Failures of which there are about 5 types, caused by various issues in the connection Process.
The 10 Sec Error message covers those things where the connect End but iChat did not receive a "BYE" message (a controlled End to the Chat) or get a failure of another sort.
Basically you were connected properly (even if you did not hear or see the Buddy) and so other event cut the connection that was not iChat related.
Can you do Video chats with any of the 6 names in Table 1 ?
http://www.ralphjohns.co.uk/ContactTesters.html
Some of those will respond to Audio Only invites.
(I just tested 4 of them and three play music and one the Audio form the Jonathon Ive Video)
Do any of those work ?
That will exclude a Modem or Router Issue with DOS or SPI on the remote end.

Please, if posting Logs, do not post any Log info after the line "Binary Images for iChat"

Screen sharing mobile account (open directory) not working

Can anybody else verify that screen sharing, through Remote Management, does not work when trying to connect to mobile accounts on 10.7 Lion?
Please note, when I say through Remote Management, I mean that under System Prefs->Sharing->Screen Sharing is disabled but Remote Management is enabled. (Remote Management being able to provide it's own screen sharing)
Also I dont mean VNC... please make sure the "VNC viewers may control my screen with password" option is turned off under System Prefs->Sharing->Remote Management->Computer Settings

I can confirm this. Same experience here on a 10.7.2 Mac.
I get a "Please verify you have entered the correct name and password".
Does this work on 10.6? I'm unable to check at the moment.

Do I need to buy Missing Sync for Palm to get memos to work

Do I need to buy Missing Sync for Palm to get memos to work for my palm? Every thing else worked just fine, but my Memo Conduit which is Disabled Conduits now.
Brian

Memos using those conduits are stored in and access using the Palm Desktop.
I too think that the Missing Sync for Palm OS is a vastly superior way to synchronize contacts, events, memos, tasks and other data that iSync is, but you can simply restore Palm Desktop memo synchronization if that is all you want to do.

You do not like the answer that is different then you being wrong. Everyone can think things about anything, but it is a black and white issue. To get a new cheaper phone, then you would have to change your plan.

Why do I need so many servers under Shared?

Besides my mac and Time Capsule, why do random servers show up under the "Shared" section of the sidebar? What is there purpose?
Thanks!

Not really because they should appear and disappear automatically unless left over from the past and just never went away. You can remove an item from your sidebar by holding down the COMMAND key then dragging the item out of the sidebar. If the servers are still active they may well reappear.

I need help with ISIGHT! I can't get it to work with MSN!

HI,
My issue is this... I have AIM/AOL and I am able to see myself on webcam.. however noone else can unless they HAVE a webcam... My first question is- "DO you have to have a WEBCAM on both ends for both people to see you?" Does the person I am chatting with HAVE to have a webcam to see me? If so WHY? They should atleast be able to see ME if I want them to... Also if they are using windows for PC platform... can they use a pc webcam and still connect with me through my isight although I am on a mac?
My second major ISSUE is.. WHY is the isight only compatible with AOL/AIM? I was told when I bought this it would be compatible with MSN Messenger for windows AND the MAC version... I have both and the isight does not show up on it... CAN ISIGHT be connected to msn messenger for MAC??? PLEASE help me!
I called APPLE tech support and they couldn't even help me! They told me to call Microsoft! Anyhow- one guy did say he was able to get his ISIGHT working with the MSN messenger for MAC platform.. do you have ANY idea how to do that?? The thing is ALL my freinds are on PC's and have MSN messenger..
ALSO- someone on mac rumors told me to look for a guy names RALPH! Said you know A LOT about mac and pc compatibility! PLEASE HELP
Bottom line - I want to use isight with msn so my msn pc friends can share webcam... I also have virtual pc software... is it easier to just get a pc webcam and do it through there? ( i tried that and it didn't work either) i need major TECH SUPPORT!
THANK YOU

Microsoft's Messenger for Mac (MSN) does not support webcams at all.
I have found the best alternative to MSN to be aMSN with macam for the webcam driver (it is a cheap usb webcam). Both are free open source projects. I guess if you use an iSight you will not need macam.
aMSN can be found here: http://amsn.sourceforge.net/
macam can be found here: http://webcam-osx.sourceforge.net/
The speed is substantially faster and it is far more stable than Mercury in my experience.
The only difficulty is the camera is often shown as being "in use by another application". To counter this I start macam, then plug in the camera (or unplug and plug back in). Then I start aMSN.

Screen Sharing and video chats don't work

I've been searching this forum for awhile and I haven't found a concrete answer to my problem, so if this question has been answered please excuse me. Ok, So here's my situation am running iChat on Mac OS 10.5.1. Whenever I am using my laptop at my school on the network their, I am able to use both screen sharing and video chat. But when I am at home, I am unable to use either one. It begins to try to start the session, but then i receive a message that tells me that a connection could not be established. I know that I have internet access, but I don't know what could be wrong with it.

After investing far to long in looking at this exact issue on my end, reading the seemingly endless threads on the exact same error, trying all the various tweeks and QT settings, bandwidth limit settings, etc etc. proposed here, I have now solved this problem, and the none of the above were part of the solution.
I have perhaps one of the the most common routers on the market, Linksys WRT54GL.
In a totally unrelated network problem (a printing issue), Linksys tech support advised me to reset my router. There is a small button on the bottom. I depressed it for 30 seconds. Rebooted everything and my printer miraculously worked. Yea, I had to reenter my WAP passkey, router admin password etc., but that took 2 secs. So, what does this have to do with iChat?.... The very next time I tried iChat video and turned on and enabled my camera, the recipient immedialty saw me. No connection error.
Problem solved, for me art least. Not sure if anyone has tried this, but makes sooooo much more sense than the other unApple like suggestions I previous tried. Hope this helps.

Connect from Windows through screen sharing (VNC) and get out of full screen mode

How do you get out of fullscreen mode?
I connect to a OS X Lion computer through a Windows computer (which actually also is remote).
I use TightVNC software on Windows to connect. It's the only VNC software I am able to connect to OS X Lion with. TightVNC is kind of weak otherwise in the way that it does not have features for OS X targets - like you can't send "command" key pushes, or even Ctrl pushes and other F2 etc keys just don't really work.
Which means I cannot exit full screened apps by way of Command-F or similar. Moving the mouse cursor to the top of the screen also does not pop down the menu (although on some occasions I have been able to do this, I'm not sure how and it's terribly hard to reproduce).
I'd need a on-screen way (like a button to click) to get out of full screen mode.
Any ideas???

Are you using TightVNC because you found it was the only VNC client that worked well with Mac OS X built-in VNC server? Or is there another reason?
Vine Server (aka OSXvnc - free to use the server)
<http://www.macupdate.com/info.php/id/11283/vine-server-%26-viewer>
plays nicer with 3rd party VNC clients, so that you could try any number of other WIndows VNC clients. Maybe one of those will do a better job of sending Command/Control/Option keys.
But if you do install Vine server make sure you turn off Mac OS X Screen Sharing (and/or Remote Managment) so that you do not conflict with port 5900. Or via Vine Server configs, tell Vine Server to use a different port number, such as 5901, then make sure you connect to the correct port from your Windows client.

Screen Sharing and Remote Login suddenly stopped working

I have had Screen Sharing and Remote Login turned on on my iMac for several weeks and they have been working fine up until now. I have been accessing the computer via VNC programs and command-line ssh logins from other computers on the same local network. When I tried to connect today, i was given the following error message.
ssh: connect to host xxx.xxx.xxx.xxx port 22: No route to host
I have all of the required settings turned on in System preferences and there are no firewalls or router settings blocking it. I connected the two computers together via ethernet cable and the error message still occurred.
I can ssh from the machine to 127.0.0.1, so the ssh server is running. I can ssh to other locations from the laptop i am attempting to connect with, so that's not the problem either. I just spent an hour on the phone with the apple tech support line and they couldn't figure anything out either. Can anybody figure something out?

have you tried the obvious - restarting the computers involved and the router?

HT4848 Gray start up screen and can't get around it.

Hello ...
Been trying to find a solution.
Have a few year old iMac with OS 10.6.8.
Just installed LaserSoft scanner software and rebooted.
Now I cannot get around the start up gray screen.
I tried every keyboard combo on start up, and command line prompts I can find, but with no luck.
Found an error of "/etc/suduers is mode 0664, should be 0440" but have no idea how to set it to what it's supposed to be.
I can't seem to locate the recovery discs, so what is one to do?
Going to the mac store will be my very last resort. It will just hog up my time more than this already has.
Any suggestions at all, and please with details if you can.

Try this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Need to Start using Family Sharing

My Wife and I use the same Apple ID and ITunes Accounts but we have separate i cloud accounts. How do I separate her from my apple id and iTunes account, create a new one for her, attach her iCloud to it and then start family sharing?

Perhaps you also need to sign in with your child's account in Settings all of the places.
Itunes and app store.

and just to verify Icloud.
Also make sure that device is running ios 8

I broke my iPhone 4s screen and display. Siri worked to make calls but now says "Siri not available, connect to the internet". How do I make Siri work again till I get my new phone?

If not connected to the Internet, either through WiFi or 3G, you can't.
