Screen Sharing not working properly

Leopard is wonderful except for iChat screen sharing. Here is what happens. I am in a video chat and invite someone to share my screen, or they invite me to share theirs. The sharing works fine. Then, when it is time to end the sharing, instead of returning to the original chat, you have to reconnect the call again. Moreover, I get communication errors and cannot reconnect until I dump the preferences and restart the machine. I have contacted the second tier of service at Apple and they are working on this, but I have heard nothing yet. Is it possible that iChat has an issue and can I just reinstall iChat from the Leopard CD?
Thanks,
Phil

After an hour if pulling out my hair, I finally had an idea of what might be causing the crash... I noticed I had my old iSight plugged in (the external firewire iSight) into my Apple Cinema Display. I unplugged it and iChat screen sharing worked PERFECTLY. You should also know that I don't have problems with my iSight, it works well on Video Chat and Audio Chat and even presentation mode but, it screwed up screen sharing.
In conclusion, if you're experiencing sudden connection losses with iChat screen sharing, check to see if you have an iSight plugged into your Mac and unplug it.

ITunes 10.6.3 home sharing not working properly

iTunes 10.6.3 home sharing not working properly. I can access with my three ATV2's watch a movie later that same day it tries to access and ATV2 just keeps trying and never gets through to the library. If I restart iTunes its fine then later can't access. I am running iTunes 10.6.3 on a i7 Mac Mini with 10.7.4. Sole job is to be iTunes server and an occasional HTPC with remote buddy running. I disabled remote buddy ajax remote feature, and file sharing is on so I can load new tracks form other macs Thats it, a vanilla install with all updates.. No problem prior but not sure if problem free period was with 10.6 earler versions or 10.5 versions. I update as warnings to do so come up. The remote app has same problem accessing the Home Share. I disabled home sharing on my iPhone and set to access the old method with 4 digit code and sees all the time and will play to my express base stations so seems to be home sharing issue because iPhone apps with home sharing on and ATV2s have issue accessing.
I'm never home but when I am I use this equipment loads and this weekend not reliable at all. I have firewall disabled, and setup is as before and is working fine. I am using Mini by ethernet and using AEBS 1st generation gigabit as router only wired to cable modem and whole house ethernet attached, latest version AEBS gigabit as a wireless bridge and 2 prior version 11n expresses and a 11g express, all expresses are set to wireless off and are connected to ethernet and then to a stereo in 3 different rooms.
I can't be only one. Considering downgrading to last version of 10.5 but not sure how to do this.
How many of you are having trouble?
Any resolutions?
How to report to Apple?
How to downgrade safely? Or is it 10.7.4?

I ran into the specific problem in another thread. There are more than 100 connections from the apple TV's to iTunes. You can do a netstat -a (windows or Mac), and verify the problem. iTunes is smart enough to stop allowing more than 100 connections but stupid to allow the ATV to create so many connections.
Now for what you really want! Set all of your ATVs to wifi only. Even setting the iTunes host to wifi might help also. I think that wifi is more unreliable, and forces connections to drop, keeping the count under 100.
I also turned off ip v6. That could help you also. I originally had problems on a Mac mini, and built a windows 7 box to try to fix the problem. The wifi trick worked on both platforms. Several of us have bug reports into apple. I have a wired house also, and am very angry to NEED to use slow wifi to overcome this problem. The ATV gen 3 has been able to keep up with 1080p over wifi, so it doesn't hurt too much. What really hurts is spending over 40 hours troubleshooting this bug.

Z2 double tap to wake up the screen is not working properly when taking it out of pocket

when i take my phone out of my pocket, the double tap function is not working properly, sometimes i have to tap over and over to wake up the screen.
do you know why? does same thing happen to yours ?
and please dont tell me not to use it. i have paid 700$ and i have right to use my phone fully functioning.
any advice ?

Actually it needs some practice, you need two gentle taps on the upper third of the phone (around the place where the clock shows on lock screen), tapping too hard or tapping on the lower part of the phone will require repeating the tapping more than one time. This is from my personal experience.

Really tired of screen sharing not working after upgrade to 10.10

I have tried everything I can think of but I simply cannot get screen sharing to work any longer when I am not within my home network.
I NEED this to work. Anyone else having huge problems getting screen sharing working when away from their home network?
Anything at all I can try at this point? Sometimes the share screen button doesnt even show, sometime it does and then says it cant
come up, sometimes my mac at home doesnt even show up in the Shared sidebar area.

I've had lots of issues with my Macs picking up new names eg. 'iMac (2)' instead of 'iMac' which led to sharing issues (screen sharing, AFP etc). I've set up new DHCP IP reservations on my router (Time Capsule) in the hope it will stop happening.

Screen Sharing not working continuously in Mountain Lion

For some reason, I cannot get Screen Sharing to work continuously. I could not get it to work at all (even though I veried the settings were correct), and after reading some posts here, I rebooted my MacBook Pro and voila! it worked - at least on my home network. However, once I get to work, I can no longer connect.
Any ideas?

And how are you trying to connect with your home Mac from work?
Are you using Apple's iCloud Back-to-My-Mac (BTMM) feature? It should handle getting through home routers?
Does you work have a Firewall and proxy servers in place? They are going to block any attempt at accessing the outside world except via corporate approved networking channels, which frequently do not include Screen Sharing. If this is the case, I might suggest TeamViewer.com as it has an option for setting a Proxy and if the company has not disabled accessing the TeamViewer.com URL, it might work.
If no corporate firewall and proxy server, and you are not using BTMM, then do you have a home router? Did you setup port forwarding for port 5900 from the internet to your home Mac? <http://portforwarding.com>
What address are you trying to connect with? I you have home router you need to use the IP address assigned by your ISP to your home router. If you do a Google search for "what is my ip address", Google will tell you your Public IP address. You need this for your home router.
BTMM and TeamViewer.com avoid the need to know your Public IP, and port forwarding. Corporate firewalls are a beast of their own, and have to be handled on a case by case basis. Some will let you get through, some will not.
If you find you are going to be using the Public IP address of your home router, then you want to get a free dynamic DNS name for you home Mac from No-IP.com or DynDNS.org and then run the dynamic DNS updating utility provided by the dynamic DNS service on your home Mac to keep the dynamic DNS name updated each time your IPS changes your public IP address.

Screen Sharing not working on server

One of the (remote) servers I manage no longer allows me to share it's screen. The error I get says that screen sharing is disabled.
I attempted to fix it using kickstart, and while kickstart reported no errors, I'm still unable to share the screen.
For reference, this is the kickstart command I used:
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -activate -configure -access -on -users admin -privs -all -restart -agent -menu
I've also noticed that there are extra interfaces enabled, that are definitely not there on my other servers. Not sure if it's related, but I thought it was worth pointing out.
Any ideas?

My Mini is running server headless and it works fine for Remote Desktop. Are you using ARD or standard Screen Sharing from OSX? Or a VNC client?
Take a look at:

For some notes on how to start the VNC server from the SSH command line.
But, screen sharing should work for you.

Screen sharing not working Lion Server

I can't connect to my Lion Server from any other Mac. I got it working for a few minutes after the first restart but I can't get it to work now. It's a Mac mini server runnning headless. I've even tried connecting it to a TV for a screen and it looks like everything is still set correctly for screen sharing under remote management. I can connect via the Server Admin app (pretty slim compared to 10.6) and via ssh fine. Services seem to be running OK.
For the life of me I can't see what the problem is. It worked fine under 10.6.8 before upgrading.

Dear all,
I had the same issue with my nokia 5800, finally I found very interesting thing, I have been doing everything to bring my phone back to original condition where simply I can touch and access the phone.
Actually the issue was with the thin plastic piece which was put on the touch screen for its protection. I was struggling to touch and access the phone but i coudnt for almost 2 weeks, it was directing me to bottom left corner touch buttons of the phone and automatically opens and activate functional which I didn't want.
Solution was, I simply removed the thin plastic layer from the phone , Now it works fine.
Hope this will help.

Home sharing not working properly on my iBook OS X

Hi, I just purchased a iBook OS X, and I'm having trouble using it. I have used Windows my whole life and this is new for me.
The problem I'm having is trying to transfer my iTunes music library from my windows of to this iBook, and I have tried doing home share and authorizing computer on iBook, but it doesn't do anything. Unfortunately my windows pc is not working properly and it freezes up every time I try to log in, so I can't really do nothing with that. I can't even check if that pc's home share is turned on, which I think it is.
Do you guys have any idea how I can transfer my music library without having to use my windows pc?
Please helppppp! I purchased this laptop from a guy, so I don't fall in the complimentary service and can't afford to pay apple care.
Thank you

IChat screen sharing not working

My elderly father just replaced his aging egg-shaped iMac with a Mac Mini. He's always had trouble really understanding UI concepts and I'm constantly having to fix things and show how to do operations repeatedly. Poor eyesight doesn't help, either. I would love to be able to share his screen from my house and avoid the ultimately frustrating experience of trying to explain how to do something over the phone or by email.
Yet, I can't get screen sharing to work. Yes, I have configured his computer to do so.
Could the problem be that he has Road Runner's slowest connection rate (something like 768 Kbs) while I have 15 Mbs? He has stubbornly refused to upgrade even to mid-level speed, even though I have offered to pay the difference. Do you think a 2 Mbs rate would allow screen sharing to work?

Someone else was having trouble with screen sharing and 10.6.4, and used this method to fix it:

Remote Desktop & Screen Sharing not working??

Hello all,
I am trying to connect to a friends computer via the Finder's Screen Sharing, I enabled the screen sharing preferences under the System Preferences, put the password, etc and had him do the same and I am not able to connect to his system. I'm sure there is something else I have to do in order to get this to work. In the Windows world I had to use the VNC. But, I remeber reading in a Snow Leopard book that this is all that had to be done in order for this to work.
Best Regards,
freesparks

I know I could never get this working between two macs of the same OS (10.5.8) over the internet with the appropriate Sharing settings set up....
Im guessing both Screen Sharing and Remote Access through iChat DO NOT work anywhere but in a LAN?

Screen Sharing Not Working (All Black)

Hi All,
Using LCCS, and since the latest Flash Player Update Screen Sharing has not been working.
Regardless if I share Desktop or specific Applications the Attendee only sees a black screen. (See Pic Attached)
Any ideas why this might be happening?
I am not sure if this is related to the latest Flash update, but I noticed the problem right after I installed.
Thanks for any help.
Dan

Hi Guys,
Thanks for getting back to me.
Hironmay
I noticed the problem once I updated to Adobe Flash Player version 10.1.102.64 Universal Binary for Macs | 7.60
I am not sure what my development team in India has done and if they upgraded to the 1.3 SDK. I will check with them, and make sure that they do and see if that fixes the problem
I am not sure if I am getting a RTE, no messages or errors are popping up it is just staying a black screen.
I will pass along the suggestions you made to my development team in India, and hopefully it helps.
I will keep you updated.
Quick question, I was looking for the notification of the latest update on the collabritive methods blog and I did not see anything there.. is there another place I should be looking for the latest news about LCCS ?
As always thanks for the help.

Screen Sharing Not Working

I have screen sharing turned on and it works fine when I'm in the house in front of the computer on the same network, but when I'm at the office trying to share the screen it is not working. I'm I doing anything wrong?
I have the Macbook Pro hooked up to my TV (main monitor). I have the computer screen on "never sleep" (computer screen is damaged from motorcycle accident-can't damage any more) and the keyboard lights turns off after 5 seconds of none use.

I'm leaving my personal MacBook pro at the house and using my office MacBook Pro trying to share the screen. I'm using the assigned vnc://ipaddress to login. What I mean by not working is that I get a message stating that my computer cannot be found. I drive home from the office (I don't do anything to the house computer) and sit in my yard and screen sharing works.
Most likely when you are in your yard, you are connecting to your home WiFi network and this by definition is the same as being in the living room.
If I need to configure my home router to port forwarding I'm not sure I know what to do and how to do it.
Depends on the make and model of router. A Google search for "Port Forward yourroutermake yourroutermodel" will most likely find instructions.
I'm talking my Mom, who lives in Louisiana, into buying a Mac and I told her I could help in Arkansas by screen sharing. So, is Port Forwarding a default feature on most routers?
Yes, most routers allow Port Forwarding, however, for your Mom there are other options.
a) Get 2 Free AOL Instant Messaging (AIM) accounts. Give one to your Mom. Now use iChat and in Mac OS X 10.5 (Leopard) there is an iChat option where you can ask your Mother to share her screen or she can click a button to export her screen to you.
b) If your mother is not going to be around when you work on her Mac, you could install an iChat add-on called Chax which has an option to always accept requests for screen sharing. Your Mother would have to be very careful about who she allows in your iChat "Buddy List". This is also an option for your work vs home situation.
c) Skype has a Mac OS X beta version that includes Screen sharing. You could use this for your Mom. No home router issues.
d) You can subscribe to Apple's MobileMe service and use the Back-to-My-Mac feature. You must make both your systems and your Mom's Mac part of your account. Is not suppose to have home router issues, but Back-to-My-Mac works best with Airport Extreme or Express routers.
e) You can use LogMeIn.com for screen sharing. No home router issues. However, LogMeIn.com is not as fast. However, it is fairly reliable and easy to get setup.
f) You can Port Forward the screen sharing ports in your and your Mom's home router.
I would like to have control of the mac at home and my Mom's new mac. How screen sharing works when I am at the house is exactly what I need. I see the other MacBook Pro in a window on my MacBook Pro computer and I have full control of the Mac.
You can get full control, you just need to deal with your home router.
Also note: Depending on how your Work network is setup, you may nave to deal with corporate firewalls that may not be happy passing your screen sharing requests.
So do you have a corporate firewall? Do you have to configure a Proxy server in System Preferences -> Network -> Advanced -> Proxy? If you do, then you may have additional hurdles connecting from work to home.
However, going from your home to your Mom's Mac only needs to deal with Port Forwarding on your Mom's home router.

Screen sharing not working with eMac lab after 3.2 update

Screen sharing no longer functions after applying the 3.2 update in our eMac labs running 10.4.10 and PPC processors. However, it still functions in our iMac labs running 10.4.10 Intel processors. Before update, I was able to screen share with all the computers in the lab. After the update, I am only able to share with one single computer at a time. Not very useful anymore for teachers to use for demonstrating purposes at our school. It definately had something to do with the update since it was working moments before the update. Please help before I have to call Apple regarding this issue. Again, it only seems to affect screen sharing across PPC eMac computers, not Intel based computers.

Through much testing at our schools, we determined that the problem lies with the update and the admin machine running ARD. If the admin machine is less than a G5 (doesn't matter if it is intel or PPC), ARD will not screen share with multiple computers (more than 3 machines) at a time. If you have a G5 admin machine, you probably will not experience this problem. Apple has yet to contact our district regarding any options for fixing the problem. We are currently in the process of shuffling computers to make sure there is a G5 admin machine in every lab to run ARD. However, I still think Apple needs to recognize this as a problem with their update. Screen sharing is a great tool for teaching class and it is too bad that with the current 3.2 update, it breaks the ability to use it with "older" G4 macs. Hence, that is why your eMac screen sharing is not working anymore. I can only hope for a prompt update to ARD to remedy this situation.

Screen Sharing not working - Black Screen

Hi
I run a Mac Mini (2010) with Snow Leopard as a media server. The MM is headless so I rely on screen sharing to control it. I connect to it using Screen Sharing on my MacBookPro (also Snow Leopard) as well as LogMeIn when at work.
I have the MM scheduled to shutdown at night and come back on in the morning. Recently after starting up I get a black screen on Screen Sharing. I've tried a lot of the tips given and none have worked. Bizarrely the screen is black on LogMeIn as well so I don't believe it's a Screen Sharing issue.
If I force a shutdown (pressing power button) then restart, Screen Sharing works fine.
Any suggestions would be appreciated.
Regards
Aidan Cooper
