Share Screen Dialog Won't Quit

I tried to do a "Share Screen" with another Mac that had frozen. The Share Screen went searching for the other computer but couldn't find it. So, I restarted the other computer and it booted back up. But now when I go back to the first computer, the Share Screen dialog is stuck on "connecting..." The Cancel button is not available. There is no close icon on the window. I used "Force Quit" to shut down the Screen Sharing application and it closed, but the "connecting" dialog stayed open. I did a relaunch on the Finder, but that didn't have any effect either. The "connecting" dialog is forced on top of all other windows, so I'm going to have to reboot the system to get rid of it.
I think this is a Snow Leopard bug. Is there anything else I can do beyond Force Quit to get this dialog box to close?

Ichat Share Screen - video won't work but i can here sound

hi .. i have a problem with ichat screen sharing . it happens when Im trying to share my friends screen for controlling is mac. so i ask to share is screen and he accepted. and now the only thing that works is the sound , i can here him talking but i cant see his desktop.
what am i doing wrong ?

Hi,
Welcome to the  Discussions
iChat Screen Sharing Connects similarly to an Video or Audio Only chat.
As you have found out it includes a Audio Only chat along side the Screen "transfer"
iChat uses one port to send the Visible Invite on port 5678 using the UDP Protocol
Video or Audio Only chats then move to one port from 16393-16402 (Usually the last one) to Make the connection.
Screen Sharing uses a Random Port for a VNC connection Along side.
This can mean if either end is using Port Forwarding to open Ports the Screen Sharing picture bit cannot get through.
This would normally mean the chat fails as both parts make up the connection.
Move to using UPnP if your routing devices (both ends) has it.
iChat 4 and 5 are the only versions that can Screen Share.
The Screen Share is "Created" by a Software "camera" within iChat.
Does the Buddy have the option in iChat's Video Menu > "Camera Enabled" ticked (On) ?
Selecting this toggles the tick On or Off and therefore the Camera On or Off.
There is also the possibility that the Software camera is not "Active" or something is wrong with it in his iChat.
There are ways of starting iChat using Terminal that can look at that.
You are getting the message in big white letters that Screen Sharing is starting ?
But you are saying it does not resolve in to his Screen.
Do you have his screen as a small window bottom Left ?
Normally you can change between the two once the Connection is active, however iChat also remembers where windows were the last time you used them and there is a vague possibility that you previously had a screen share going On when you closed/Quit iChat with your Screen as the "front" one.

After upgrading to Yosemite, I am unable to share screen with Macbook Pro

After upgrading to Yosemite 10.10 on a 2008 MacBook Pro I am unable to "Share Screen" using my authorized user account. It worked fine before I upgraded to Yosemite.
I can access "Share Screen" by "requesting permission", but of course this doesn't work unless I am sitting right by the MacBook Pro to give myself permission, which defeats my original purpose for using "Share Screen".
I attempted to add another authorized "Share Screen" user account, but was unable to access the list of add "Groups and Users" on the host MacBook Pro from the "Share Screen" dialog box. The dialog box pops up, when I press "+" to add another user, but the list of users fails to appear. I assume the list of authorized users for screen share has somehow become corrupt.
All other ways to access "sharing user" accounts appear to be working properly. I can add and remove other "sharing users" without problems. For example, I can add a new authorized "file share" user and share files without problems.
I ran Disk Utility in Recovery Mode and normal mode and corrected all errors, and user permissions on both machines. I also ran "resetpassword" from Terminal in Recovery Mode and "reset" user permissions. I am not an experienced Terminal or Recovery Mode user though.
I also tried turning the Firewall off, to no avail.
I am attempting to access "Screen Share" on the MacBook Pro via a Macbook Air 13" manufactured mid 2013 also with Yosemite 10.10, however, I also attempted with an older MacBook Air which experiences the same problem.

Thanks for the idea but it did not work, I do not know why it is asking me for a password which I never needed before for a guest to use the computer? I have tried everything and I do not know which password it wants? I do not see any option for a password for the guest account, to create one or delete one or modify it? Maybe this bug\problem will be addressed in a future update?

Your post somehow found its way to a little-viewed forum for an obsolete Apple productivity program. I have asked the Hosts to move you to a more appropriate forum for your product.

Where'd my "Share Screen" ability go?

I have three Macs and quite often use one to access another and another with the "Share Screen" option in the Finder. Simple and easy, been using it since it was implemented and it really is a life saver at times. About two weeks ago two of my systems stopped talking to each other but only in the "Share Screen" option. Here's what I know; I can still access the drives, files etc on my other systems using the finder but not the screen sharing. I have checked and even stopped and restarted all of the sharing options in the Sharing Preferences. Now, the strange part is that my two main systems, a Mac Pro and a Macbook Pro are the ones that won't screen share. My wife's Macbook is still available to be shared by both of my systems. I can access her system anytime from either one of mine but cannot go between mine. It just doesn't make sense. Was there an update recently to the OS or security settings that have affected anyone else? The timing seems to work to be around the time 10.5.8 came out.
Any help would be greatly appreciated.

Okay, so, since my post nothing has changed with my ability to screen share between the three systems. What has changed is I've installed Snow Leopard on the two systems that won't share (but had previously) and also run the permissions check and repair as suggested. So an upgrade to the OS and a permissions repair on both systems but not the third. And still the situation remains that I can't share between the Macbook Pro and my Mac Pro but can share any which way I like from my wife's Macbook that is still just running Leopard.
Not sure if I mentioned or not and if this helps in anyone's possible diagnosis but it's just the screen sharing that isn't sharing. I still have access to the files from system to system but can't share screens.
Thanks again.

Mail won't quit, also won't force quit

Following problem:
Mail does not hang, but also won't quit. The quit menu item is even greyed out. The Mail program prevents a restart (dialog after timout saying Mail canceled the restart) and also will not force quit. I've tried force quiting from the context menu on the dock, and also from the force quit dialog in the apple menu.
The only way to get shut down is to quit the WindowServer process from within the Activity Monitor, which causes a sort of "log out" to occur, meaning that I end up in the login screen. From here I can shut down or restart normally.
My OS is up to date with all patches. The problem persists (in fact I would say its only about 3 weeks old) and happens quite regularly (ca. 5 times/week.)
dual 1.8 G5 Mac OS X (10.4.5)

I did this yesterday...with same problems. Create a new user in system pref-accounts. Make sure you enable fast user switching and give it admin access. Then, switch over to new account (top right corner of menu bar)
In the new account, set up a new mail account with your info. Your mail should come back automatically. Then, you'll need to put the mail plist file that's in your user folder on a thumb drive. Go back to your main user account and replace that file in the same area. THEN, open mail and see if it fixes it. It did for me after pulling my hair out for 24 hours...

I've tried to troubleshoot downloading Firefox but it won't open on Windows XP. The Firefox Update box with the hour glass symbol runs for hours. Then I have trouble even shutting down. When I click on Firefox, no window, program won't quit, etc....

Windows XP. I used to use Firefox and it worked okay. I'm not sure why I downloaded a new version but it won't open. The window that says "Firefox Update" continues to try to load. Hour glass symbol, for hours. If I try to click on the Desktop symbol, Nothing. Then when I try to shut down, it's slow, programs won't quit, or it freezes. I've removed Firefox completely and tried downloading again with the same results. Even with the latest version. Shit. Whassup?

Hi zenithtwc, to test whether this is a settings issue, could you do a three-minute experiment?
'''Create a new Firefox profile'''
A new profile will have your system-installed plugins (e.g., Flash) and extensions (e.g., security suite toolbars), but no themes, other extensions, or other customizations. It also should have completely fresh settings databases and a fresh cache folder.
Exit Firefox and start up in the Profile Manager using Start > search box (or Run):
firefox.exe -P
''Don't delete anything here.'' Any time you want to switch profiles, exit Firefox and return to this dialog.
Click the Create Profile button, assign a name like Test731, and skip the option to change the folder location. Then start Firefox in the new profile you created.
Can it reach the internet?
When returning to the Profile Manager, you might be tempted to use the Delete Profile button. But... it's a bit too easy to accidentally delete your "real" profile, so I recommend resisting the temptation. If you do want to clean up later, I suggest making a backup of all your profiles first in case something were to go wrong.

Finder Share Screen Snow Leopard to Leopard Not Working

Trying to use Share Screen from my new Snow Leopard install to a Leopard machine but only getting a black screen. Have rebooted both machines but still get the same result.

HI,
Must be the heat wave Do this on the Mac running Snow Leopard.
Try deleting this file.
com.apple.ScreenSharing.plist
/Users/YourName/Library/Preferences.
Drag that file from the Preferences folder to the Trash, empty the Trash and restart both Macs.
I'm sure you have File Sharing turned on in System Preferences/Sharing on the SL Mac and Personal File Sharing on the Leopard Mac ??
Sometimes after you do the setup, it helps to restart both machines...
If you haven't done so since upgrading to SL, repair disk permissions on the Mac running SL.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.

Skype call share screen not working on Windows 7

To see the Skype version, in Skype open Help -> About Skype.

Hello Skype community! I have a little bit of a problem with my share screen function. This is on Windows 7, and it used to be fine before. My friend's screen, (We'll call her Flower for now), can show up just fine on my screen. But Flower cannot see my screen on her skype call. Screenshot Flower's Laptop is also running Windows 7. I've tried quitting Skype, and even re-downloading it. Sadly, I'm not so sure what version of Skype Flower's running, or mine. Any help is appreciated!

Display won't sleep and screen saver won't sart

I upgraded to the new OS and the display won't sleep and screen saver won't come on. Help please.

Long shot.
Do a backup.
Quit the application.
In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then go to Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
Restart the computer, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer ones.
If you want to make your user library permanently visible, run the below command in Applications/Utilities/Terminal.
chflags nohidden ~/Library/
You will need to do that after any updates.

When I touch the email icon there is a draft email stuck on the screen that won't go away if I delete or save it. I've already tried deleting and resetting the email account which didn't work. How do I get rid of it?

I have the new iPad 3 and every time I touch the email icon there is a draft message stuck on the screen that won't disappear even if I touch save or delete. I've tried removing the email account and putting it back on which didn't work either. How do I get this draft to disappear?

Reboot 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 - let go of the buttons.
Or Quit the mail app.
Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button.
Go back to mail and see if it is fixed.

Share screen crash

Hi All,
Thanks in advance for help. I just bought a new Mac mini. The plan was to use it as a iTunes server for appleTV. I set it up using hdmi connected to flat screen, but planned to control it when necessary from my Mac desktop. Not particularly savvy with computers, but share screen seems simple. I just can't get it to work.
I turned on sharing for the mac mini. The mac mini shows up in my finder and it seems like I can access files, but when I try to share screen it just says "connecting..." Cancel is grayed out and it doesn't show up in the Force Quit menu. I have to reboot.
I used the same admin name and password on both machines. Could that cause a problem? When the share screen password screen comes up it pre-populates with my first name. If I add my last name I get an error. If I simply enter my password I get the infinite connecting loop.
Any suggestions?
best regards,
ralph

incidentally, I've been able to connect to two other macbooks. I just can't connect to the mac mini. Any known issues or recommendations? Thanks again.

Share Screen Cuts Off Along With Videos

Recently, during my video calls the share screen cuts off both webcams go out along with it.
When trying to turn the webcams back on they just keep circling and we would have to end the call and call back for our webcam videos to show up.
Also the webcam video randomly gets blurry even when the connection is good and shows its still white on the connetion.
When trying to turn the video off and back on to see if it would help it will come back clear for a few seconds then revert back to a blurry image.
The video is normally a rectangle shape when its clear, but crops into a small square when blurred.
Once again have to end the call and call back.

Yes. The MBair uses magnets to detect when the screen is closed. When you move a magnet along the edge, the MBair thinks you've closed the screen and puts it to sleep.
Edit: This won't hurt your MBair.

Screensharing login window won't quit

I have had this problem over a year now. We have 3 Macs in the house - two iMacs and my MacBook Pro. Both the iMacs have screensharing enabled in their System Preferences. On my MBP, in the Finder window sidebar I select one of the other mac to view. I get the usual screensharing login window, I enter the info. and hit connect and it never connects. The window will never quit neither can I dismiss the window even by quitting screen sharing app. I have not been able to find the exact process that is responsible for this window in the Activity Monitor so I could atleast terminate the process there. The only way I could then get out of the mess is to log out and then log in. Here's a little caveat. If when the login window is sitting there stubbornly trying to log in and I have quit the Screensharing app, I go back to the Finder window, select the same Mac and hit Share Screen button, it will immediately connect. But the log in window will still sit there and there is no way I can dismiss it other than to log out and log in. - It's really annoying I have not been able to figure out as to why this happens. Anyone know about this? It's been about 15 minutes now, and the window is still there. It doesn't time out either! Well, I got to go log out now (after I post this post)

Yes, I have had this issue and it is quite annoying. If you go to Activity Monitor and Force Quit 'NetAuthAgent,' it will kill the login box (make sure you have 'All Processes' listed in Activity Monitor). How to keep it from happening, I have no idea, but this at least gets the login box to go away.

Out of the blue flickering and iCal won't quit

We bought our iMac 20" last January 2008 and it has worked perfectly. I have installed all updates. After the last update (and I really don't know if it is just coincidence...) iCal won't quit unless it is forced. All data is gone. It might also have something to do with the last time I synced my iPod...?
More troubling, the screen has started flickering... almost shutting down at points. However, it is not on a regular basis and seemingly out of the blue...?
Any help or advice would be greatly appreciated.

Wilrez,
Welcome to Apple Discussions.
Regarding the iCal issue, if you used Software Update for installing OS X 10.5.7, you may want to try reinstalling the update using the Mac OS X 10.5.7 Combo Update.
Let us know what happens with both problems after the reinstallation.
;~)
