IChat screen sharing- shared screen is green/grey pixelated

Have a strange problem trying to share the screen of my parent's MacBook Pro: request accepted, but I can't see their screen. I get a first glimpse and it works, but then it degrades to grey/green pixelated, in general, unreadable.
Both computers are running Lion, all updates installed. Any ideas on how to fix this? Have toggled screen sharing in Settings, but am stumped as to why this happens. They also have an iMac, and have no problem screen sharing. Only difference is that the iMac is connected to internet by ethernet, the MacBook Pro via wifi.

Hi,
As a Starting point go to iChat Menu > Preferences > Video Section and change the Bandwidth Drop down to 500kbps
Do this at both ends.

Green & Blue pixels of death - Hotfix

Occasionally my screen will boot swarming with green & blue pixel sized dots. If I take a screenshot, and look at that screenshot on another computer, they are not visible. I used to reboot until they disappeared, and then started putting the display to sleep and waking it up, but encountered sleep problems with Leopard. I've since found a faster, more reliable way to chase them away.
- Change the resolution of your screen one lower, and then back to your desired resolution -

Stop changing the screen resolution.
There's a few workarounds with this, sadly no fixes.
*1, When it happens. Press the power button/standby button on the side of the display and unplug the display (from the mains) gives it two seconds and plug it back in. As it's powered back on, the dancing pixels are gone and its saves you having to reboot/sleep/restart all the time.*
*2, Get dockables. http://getdockables.com/ It has the sleep display app that you can put in your dock and activate to quickly get rid of the dancing swines.*
No need for messing with resolution changing, or restarts etc.
*3, The most simplest one of all. When your display goes to sleep, before you wake it up and the screen is covered in dancing pixels. Power off the display via the button on the side of the screen. Then tap the key (keyboard) or move the mouse to wake up the machine. Then tap the power button on the side of the display again.* The screen will be clear from dancing pixels. You'll have to do this each time when it enters sleep.
I can't guarantee you'll never get them. As I have tested this many times and I haven't had it with workaround 3. Sure it may be a pain, but its the only way I have found testing this.
Something triggers the signal to become messed up, and I'm betting its driver related because the OS sends the display to go to sleep. So something must malfunction with the driver/signal to cause all the dancing pixels upon wake up.
As it is no rocket science if somebody has replaced display after display, system after system, graphics card after graphics card and the problem remains.
This is such a bad intermittent problem, that Apple are not aware of.

Problem using file sharing and screen sharing in Leopard

I have Mac OS 10.5 Leopard installed on 4 computers in a Home Network and have a problem with sharing files and using screen sharing. Here is my setup.
MacBook Pro with my logon ID
MacBook Pro with my fiancee's logon ID
Mac Mini with both of our logon ID's
Mac Pro with both of our logon ID's
The problem I have is I am able to access the Mac Mini computer where we have an external Hard Drive connected for data. She is also able to access it. The only problem is we have it set up to only share this external USB drive. Yet for both of us it shares the external drive along with the internal Macintosh HD. Fortunately this is not a very big deal but since I'm not sharing all those drives why is it doing this?
Also, I am able to connect from the Mac Mini for example to my MBP and vice versa for screen sharing along with file sharing. Yet if she tries to connect to the Mac Pro from her MBP and vice versa it won't. It simply times out and will never connect for screen sharing or file sharing but yet the Finder shows the Mac Pro. We have a 2nd hard drive in the Mac Pro which is the one set up for file sharing. I am also unable to connect to the Mac Pro's HD. Everything appears to be set up correctly. For my MBP on the Finder it shows the Mac Pro but once again I am unable to connect to it for screen sharing or file sharing.
Also, not sure if it's related but even for her MBP she is unable to connect to it from any other computer in our network although it's set up for file sharing and screen sharing so I'm not sure if it's related to her logon ID. Then again as mentioned above neither of us can connect to the Mac Pro.
I tried to make the above sound as simple as possible. I am relatively new to networking and of course Leopard but even on the Mac Pro all settings sound the same as on the Mac Mini where we can both connect to. The only big difference is on the Mini we are connect to a USB external drive, on the Mac Pro an internal drive. Is there something I could have overlooked or are there known issues with Leopard's sharing features?
We both have .mac but since we are using this on an internal network (some wi-fi, some wired, all through an Airport Base Station Extreme) I would think this has nothing to do with Back to my Mac.
I appreciate any help with the above.

When trying to share my screen in iChat, the other person only sees green

When I try to share my screen with someone using iChat, the person sharing it with me cannot see anything on my screen. I've tried reinstalling Mac OS on my computer but it hasn't helped...what can I do?!

HI,
To be clear, iOS = iPhone and iPad and some iPod Touches and the Operating System they use.
Mac OS X = the Operating System Mac computers use.
Regarding the AOL account, is this actually from AOL and have the Chat/Messaging option enabled ?
Or is it a Name registered with the AIM part of AIM ?
You can have AOL as your ISP and have an email and User ID from them.
This needs to have the ability to use the name as a Chat name enabled (or at least it used to)
AIM, which actually stands for AOL Instant Messaging has it's own registration site.
Nowadays you register for a AIM email (although activating it for mail is another additional step).
It used to be that the bit before the @aim.com bit was the user name you used in Chat applications that could use AIM.
Previous to the current system you could in fact register just a Screen Name with them.
Apple (and a few US based ISPs) also have agreements with AIM that their (Apple, etc.) emails are recognised as Valid AIM Screen Names.
This means those issued by Apple ending in @mac.com, @me.com issued from the iCloud registration and @icloud.com.
(You do have to keep your password to 16 characters or less.)
From what you are saying you seem to be sure that you can see each other as On Line in your respective AIM Buddy lists ?
In Messages in both Mountain Lion and Mavericks you do not have to display the Buddy lists
(See the Window Menu plus the General Section of the Preferences to separate them)
Are you also saying that in the Video menu the option to allow Screen Shares is Enabled ?
Is it done at both ends ?
In iChat you could offer to Share your Screen with a Buddy without the option being On (they could not ask to share yours or offer theirs). I have not tested this in Messages.

File sharing and screen sharing

I rarely use facetime, file sharing or screen sharing but I tried a few nights ago.
I went through the configurations, settings and still was not able to screen or file share with my buddy.
Any solutions????

Unfortunately you do not have any options, the iPad one cannot be used for mirroring.

Screen Sharing / ARD. Who's sharing my screen?

I'm trying this on both Mavericks and Yosemite. Screen Sharing or Apple Remote Desktop.
If either of those apps on another Mac are sharing my screen on my Mac, I'm pretty sure in older version of OS X there was a menu item in the menu bar that allowed me to see who was sharing my screen, and disconnect them or force them into observe mode if I wanted to.
I can't seem to find any option like that in more recent versions of OS X. Isn't there any way to see who's observing or sharing my screen? The menu item is still there but it doesn't have any of that information in it that I can see.
Am I missing something? Any direction or suggestions appreciated!
Thanks!
David.

File sharing and screen sharing stop working suddenly

I have been using file sharing and screen sharing without any issues between my mac mini (10.7 Lion) and MBA (10.8 ML). However, both suddenly stopped working the other day - that is, I saw the mac mini on my MBA's list of Devices, but when I clicked on a drive or on screen sharing, it just said could not connect. I rebooted the computer and they started working again...but a few hours later suddenly stopped. I toggled those options on/off in the Sharing section of Sys Prefs, and they started working fine again...but then stopped again. It seems no matter what I do, file and screen sharing just stop working after a short period of time after being enabled.
Ideas?

Turns out the problem was that I had a daisey-chained ethernet switch. My mac mini was on an ethernet switch that was not visible to my wireless network. Make sure that your ethernet switch is somehow directly connected to whatever is serving as your DHCP server, then your wireless devices should see it.

Trying to load PSE 12 onto laotop running Windows 7 but it gets as far as installing shared technolgies screen & then stops stating that there is a fault with the shared technologies. It then reweinds

I have been trying to load my photoshop elements edition 12 onto my laptop running windows 7 but it gets as far as the shared technologies screen & stops. It the does a roll back. I have followed the fix guidelines & cleared the 2 relevent files in the common files section of the computer several times but it still never gets past that screen. Can anybody suggest what the compatibility issue might be with widows 7 & elements 12 program? Any help would be much appreciated, its my last day on the count down to set up. I have been trying every day.

My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

Changing screen size for screen sharing

Is there a way to change the screen size for screen sharing?
I have a 13" macbook and a G5 with a 20" monitor. When I use RDC to a PC it automatically adjusts to use the full screen on the G5 and when I use VNC to a linux system I can create a vncserver with any arbitrary geometry that I want, but when I use screen sharing all I seem to be able to get is a 13" screen. I can use JollysFast VNC, and view it full-screen, but it's still just 1280x800.
So, is there anyway to create a virtual window so that I can take better advantage the screen on my G5 when screen sharing to my macbook?
Thanks,
Rob

Well, the question should really have been, "What is the ideal page width for the iPad?".
The answer is that there isn't one since the iPad, like most portable devices, has two screen widths depending on whether its used in portrait or landscape mode.
If you are designing a layout specifically for the iPad, one solution is to use a folding design where the sidebar folds down to the bottom in portrait and jumps back up to the side in landscape. This will only work for personal computers and iPads.
The popular way of designing a layout to suit a large range of portable devices is to use a liquid, or semi liquid, layout that will automatically adjust to the fixed width browsers used on these devices.
Something like this...
Neither of these methods are possible using a template based editor like iWeb and this is probably one of the main reasons that Apple has given up on the application. Surfing the internet on mobile devices is growing daily and its now become essential to have a mobile version of your website or one that can be viewed on all devices.

File sharing or screen sharing-remotely

Hello
I swear I accomplished this once and it was simple but I cannot do it now.
I want to connect with my sister's MacBook from my MacBook Pro. She is in Georgia, I am in NY. Obviously this is not a local network connection.
I know the basic set up and have done everything I can think of or have read about.
File Sharing and Screen Sharing are on, on both computers
Firewalls Off. No password required.
In Screen Sharing > Computer Settings "anyone may request permission..." is checked.
Allow access for All users.
In File Sharing > Options both AFP and FTP are checked.
Shared Folders: Public Folder...Users Everyone. And I also clicked the + and located her name in my address book and selected it. I was prompted for a password for her. So I entered "her" password, not mine. (Is that right?) After several failed attempts I tried repeating this but entering my password.
Next, I asked her on the phone to tell me what it says on her computer under File Sharing On. (afp://192...etc. OR the name listed after that.
Then I went to my Go > Connect To Server and entered that info. I tried the afp address; I tried the name; I tried variations on both; I tried going back over to Screen Sharing and entering the vnc://192...etc number as well as the browse for name.
Over and over and over. I also did all this from my desktop Mac Pro as well. But all I get is Connection Failed, the server "192...and so on may not exist or it is unavailable at this time. Check server name, bah, blah.
What am I missing? Anyone, please.

Hang on, are you implying that:
aptop:~ admin$ sudo scp -Epr /Users/[email protected]:/Users/iristestlocaluser
Password:
Password:
Password:
Should be:
aptop:~ admin$ sudo scp -Epr /Users/[email protected]:/Users/iristestlocaluser

Lag/computer is slow when sharing the screen durin...

Hi everyone. I have a question. (New here on the forum so hope I'm doing this correctly)
Me and my friend often have a Skype Call where one shares the screen. (One plays a game while the other one watches.) However, whenever I share the screen, there is this immense lag for me, making it pretty hard to do anything while screen sharing. Even when I simply browse the internet with nothing else but the screen sharing open makes my computer really slow. My computer is fast without screen sharing.
The funny thing is that everything else in Skype works just fine. When I simply chat or when I'm calling someone without the screen sharing, my computer just works great and fast. And whenever my friend is the one sharing the screen with me, she is experiencing no lag at all. It's just when I share my screen there's lots of lag.
So I was wondering what the problem here could be. The connection between us seems good enough. After all, regular calls are just fine. Does anyone know what the problem could be and how to fix it? Thanks a lot.

@AutoRepairMedia, Can you please reproduce the issue and provide logs as described in this link https://support.skype.com/en/faq/FA12321/how-do-i-create-log-files under Skype for Windows Desktop and attach it to your post?
Can you also try to share only a smaller window since if you are sending a high resolution contect, it is quite cpu heavy to encode such a video.
Thank you

MacBook Pro 17" late 2009 - Black screen on boot, not even a grey screen

Got a monstrous problem.
Started up my MacBook Pro (bought in Feb. This year, core 2 duo 2.88GHz/4 Gb RAM - basically the top specced model.)
Booted up today, no grey start-up screen. No screen at all. Yet I can still log into Snow Leopard, but again no screen. Rebooted into boot camp, heard windows start. Managed to log in again no screen. Volume controls, keyboard illumination work. Just a black screen.
I have tried resetting PRAM, etc. with no success. Cannot use hardware test as the screen simply does not start.
Any ideas before I throw the effing thing from a 5th floor window in frustration?
Is this the Nvidia problem other folk have experienced?
I am tempted to ask for a new machine spending 2 months on and off with my previous MacBook Pro in and out of repair if this is a hardware problem that has been fixed in recent Macs.
Regards,
J

I had the same problem just now. My 15" MBP (6.2). I followed the following steps and it worked for me. I used another Mac in my house to use screen sharing to accomplish these things:
1) access the /private/var/vm/ directory on the nonworking computer from the working computer. This is invisble so you will have to press cmdshiftg in the finder and go to /volumes/YOURHARDDISKNAME/private/var/vm to get there or use an application that lets you view invisble folders like PathFinder.
2) delete the sleepimage file
3) delete the /system/library/extensions.mkext file
4) eject the drive (drag to the trash)
5) press the power button to turn off the non working computer
6) turn the nonworking computer back on normally(cross your fingers) then if it works,
7) open up the the terminal.app in /applications/utilities
8) type sudo pmset -a hibernatemode 0
9) make sure there is no sleepimage file again
That worked for me...hope it helps for you!

My ipad screen is shimmering green and pixelated. What's happening

My ipad screen is shimmering and pixelated. I've tried restarting and restoring from backup. Everything still seems to work, but the screen looks shimmery and pixelated. How do I fix this?

I have an old iPad 3 that has taken a beating, and the screen occasionally shifts colors (blue, green, or red). It would look about like this:
http://ipadhelp.com/wp-content/uploads/2013/10/ipad-screen-colour-problem-620x40 0.jpg
This is going to sound dumb, but this always fixes it for me:
Lay the ipad flat on your lap, open your hand, and with fingers spread, gently but firmly smack the screen of the iPad. I sometimes have to do it 3-5 times (mostly because I'm afraid to hit it too hard!), but it consistently resolves the problem for me.
