Screen sharing- not showing who is on my mac

i've got screen sharing setup on all our macs and works great- HOWEVER, on occasion, a number of things can happen:
1- i am unable to access a computer even though i accessed it earlier; i need to restart the computer and then it works
2- when i shut down the computer, a message pops up that 2users are accessing the computer though there is only one or even none on the network that can do so and the remote computer icon shows only 1computer address or no icon present (does that mean someone is hacking my computer?)
3- when i shut down the computer, a message pops up that there is a user and there is no remote computer icon visible (again, is someone hacking my computer?)
2 and 3 above concern me the most especially since at times i don't see the screen sharing icon, so don't know who's accessing the computer... and no one knows how to access my main computer which is where this problem occurs. 1 happens on the other macs when trying to access the main computer.
i've got my network running on a timecapsule with WPA2 personal security, password for timecapsule disk, password for computers, screen sharing set to admin only with no other people listed for access so a bit concerned about this would GREATLY appreciate the help/information anyone has!
thanks
ps- i also had this problem in snow leopard

The upgrade just showed up for me when the criteria was met. Try reindexing your Mac.

IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black

IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black!!

It's happened to me before as well. Try holding both lock(top right) and home buttons simultaneously until u see a slight flash of wight then just reboot it normally. If that doesn't work try restoring your device from itunes

TS3276 the images (attachments) are automatically resized (smaller) when I send them to a customer. My email screen does not show a drop down menu box where you can leave as actual size. Is there a setting elsewhere that can be set.

Any suggestions on problem I have. I receive images, say a file that is 3 mgs through email on Safari mail and when I try to resend it or forward it or any other larger file, when it sends the file is reduced by about 1/3. My screen does not show and drop down menu with a feature to keep actual size or reduce that is suggested when I looked up solutions to the problem. I can't find a setting anywhere in mail that I can change to make sure my files are kept at actual size. I figure a setting got changed -don't know how - but it happened about a month ago. Caused problems as I work in graphics can't send files to clients as they come out too small. Any suggestions on how to fix.
Thanks

What email program are you using? And what do you mean by "Safari mail"?

When printing an AutoCAD-exported PDF file, the paper version has lines that screen does not show

Hello,
We were contacted by our customer, a landscape architectural company that uses our product, M-Color, (http://m-color.com) to plot AutoCAD drawings with required preferences and effects.
However, they provided us with a sample PDF files, that contain examples of scanned drawings, that have some "ghost lines" at the drawings that the screen does not show.
We tracked the issue and it appears to be an issue with Adobe Reader pringing. We tried many versions from 8.0 version onwards to the latest versions available in public, all represent the same issue.
This may be an issue of the original drawing having some line that was not marked ending at some point.
The zip file within the link below has three PDF files, two from the company that brought this issue to our awareness and the one with name "scanstation" is printed by me, and then scanned with markings to explain the issue.
Any ideas what would be the best solution to solve this issue?

That usually fixes ghosting...

I am not sure what's happening with IE9 (no live site) but I had real problems viewing your code in Live View - until I removed the HTML comment marked below. Basically your site was viewable in Design View but as soon a I hit Live view, it disappeared - much like IE9. See if removing the comment solves your issue.

Element Entry Screen does not show value

I have created an element xxtest123, created a fast formula, and the formula result contain the direct result to this element.
But before creating fast formula I did following steps.
Created Input Values
The input values this element has are
Pay Value, Hire Date and Date Of Birth all are non enterable by user, and Database Items boxes corresponding to these values are checked.
Created Element Link
I, later linked it to a payroll and checked box Standard on the element link screen.
Now issue is after running Payroll I can see the SOE report and Run Result Screen shows the expected result
But the element entry screen does not show the values. Rather the fields are simply blank.
Can anyone please help me why it is behaving such a way?

Thanx Sharath for your quick response.
But I have run QuickPay for that employee.
After running QuickPay the input values names are coming into element entry value screen.
But it is not showing the value corresponding to the element input value names.
Thanks,
Pankaj Kedia

Mail will not show new emails on my Mac Air but sends OK. Mail server is working

Hello
As I said above, Mail will not show new emails on my Mac Air but sends mails OK. The Mail server is working because my iPad is receiving and displaying incoming messages.
Your advice is most welcome.
Thanks!

Thunderbird successfully displays all of my e-mail accounts in the list of accounts and displays all of the inboxes correctly however it doesn't display the e-mails at my newest address in the unified inbox.

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.

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 exactly the same as the host computer's screen

Hi all
I am using a mac mini as a media server connected via HDMI to my big TV downstairs. I am using screen sharing from my macbook air to do little tasks while not downstairs. This has been a very good setup.
One thing I wanted to do is maintain my iphoto library - going through old albums, confirming faces, red-eye etc. whatever.
Using screen sharing works for this, mostly.
When I choose a photo and click "edit", my TV downstairs shows the photo fine, but my screen sharing on my laptop shows nothing but black where the photo should be. When I zoom in, I see the navigator window appear (with the image) but I do not see the photo itself. I am including a screenshot. Note how at the bottom, you can see images, and in the zoom window you can see that there is an image there, but the image field itself is empty. On my TV I can see the image (a squirrel, as it turns out).
Others I have talked to about this claim that some video sources do not "play well" with screen sharing and/or VNC. I haven't encountered these things but I do recall old versions of windows would only display a movie on one of two screens, even when the screens were mirrored (a big pain for presentations if I recall)
Hoping that this is a bug in screen sharing that apple can fix? anyone else have this problem? anyone else can try this and confirm?
The mac mini isn't running Lion yet but the macbook air is. Other than that all software etc is up to date.
I tried screen sharing on an older laptop running the same os as the mini (snow leopard) and the same thing happens, so it isn't a problem running between 10.6 and 10.7.

I saw similar problems. Please see my Aug 21 post on vnc at https://discussions.apple.com/thread/3267893
