OS X Screen Sharing doesn't work after Mavericks Upgrade

I have upgraded my 3x machines to Mavericks and Screen Sharing no longer works. I have tried this with and without firewalls on. File Sharing works but Screen Sharing will say connecting for a LONG time and then say that it's not enabled and to go turn it on...
help?

I have seen a couple people talk about this as well, but wasn't the same thing..

I believe this is the easiest way to resolve any screensharing issues in MacOSX: Solution: Reset the computer list in Screen Sharing. To acomplish that install OnyX. By the way a great tool for your Mac maintenance.
Go to Cleaning>Misc. and
check My Computers list in Screen Sharing.
Press Execute and wait until it finish.
Restart your computer.
I hope this helps.

Screen Sharing doesn't work after updating to Remote Desktop 3.6.1

Hi everyone!
I hope others can help. We just noticed this at two different schools today after upgrading to 3.6.1. We upgraded Admin and Client Apple Remote Desktop to ARD 3.6.1 today and now we cannot share our screens with the clients. It turns black, hangs, then returns the client to its original desktop.
We tried from a 3.5.1 admin machine, and it still works fine as it used to.
We feel like the issue is 3.6.1, but cannot find any support for the issue online.
Other troubleshooting steps:
1) emptied user and system Caches
2) restarted all units
3) tried 3.6.1 admin to 3.5.1 clients, no luck
4) tried 3.6.1 admin to 3.6.1 clients, no luck
5) checked for loops in the network, nothing.
We can perform most other tasks like controlling the clients and copying files, but not screen sharing.
Thank you for your help!

All right! Total workaround here, and no fix, but at least we're able to Screen Share in ARD now. This is how we downgraded to 3.5.1 Admin in Apple Remote Desktop. The only hiccup that may not work for most is that you must have an older Remote Desktop file on hand. (hopefully from a computer that was not upgraded which was our case).
Here is what we did...
1) Login as an admin.
2) Throw out the Remote Desktop app (in Applications)
3) From another computer, drag in an old Remote Desktop app into your Applications folder
4) Throw out the "RemoteManagement" folder inside System/Library/CoreServices
5) From support.apple.com/downloads, download Remote Desktop 3.5.1 (both the Client and Admin installers).
6) Run the Admin install first, then the Client Install.
I did the above steps in two schools in a different order, but I wrote it this way to make it more streamlined. I never had to re-enter the Serial # or anything. Once I did the steps above, it just worked again.
Hope this helps you!

Lync screen sharing doesn't work in Windows 10 Technical Preview (9879 Build)

Why Lync screen sharing doesn't work in Windows 10 Technical Preview?
It works well Windows 8.1, but why not in Windows 10?

Hi PriTeddy,
Thanks for your feedback.
As Paul Adare said, Microsoft has noticed such issue, they are listed in following blog:
http://blogs.windows.com/bloggingwindows/2014/11/12/new-build-available-to-the-windows-insider-program/
Some known problems:
As with the last build, you’re getting hot-off-the-presses code which means there are a few issues. We’ll be publishing WU updates shortly to fix the first two, but the remainder will not be fixed for 9879.
•In some cases you may get a black screen when trying to log-in or unlock. The only option is to hold the power button to hard reboot.
•You will be unable to connect to Distributed File System network locations.
•Some systems may see disk growth of 20GB+ due to driver install duplication. On systems with low disk space this can block setup and cause a rollback to the previous build.
•Skype calls will disconnect and Music will stop playing if those apps are minimized.
•There are several known issues with screen sharing with Lync.
Let’s wait for next builds.

Why is Time machine backup not working after Mavericks upgrade?

Why is Time machine backup not working after Mavericks upgrade?

I had the same problem due to the Fire Wire port. Apple tested it told me it is OK!, I tried a new cable, and have tested both ports on my back up device. I find it strange that as soon as I installed Mavericks. The drive does work using USB. It could be a coincidence, I don't absolutely know at this point, my back up drive ports could stop working, but I doubt it!

Re: Safari 7.0 zoom not working after Mavericks upgrade.

Hey there sarunelis,
It sounds like after updating to 10.9 the zoom function is not functioning at all. It sounds like you may need to check for 3rd party plugins. This article will help you check for that.

Screen sharing doesn't work on headless mini

I have a headless Mac Mini that has been running 10.5 and 10.6 for years and I've never had any problems with screen sharing.
I now update to Lion and as soon as there's no screen attached I can no longer use Screen Sharing!
There is absolutely no way I can have a screen perminently attached to the machine.
Any ideas of how to fix this behaviour?
I've tried rebooting with no screen attached and that just hung the server at boot time.

I've found a work around.
Connect the screen and then connect to the machine via Screen Sharing
Then change Screen Sharing from Hardware display to Virtual display.
Then you can disconnect the screen and Screen Sharing continues to work. (At least so far)

Screen Sharing Doesn't Work

Hi!
I am having problems getting screen sharing to work. When starting a session I get an error message saying iChat is unable to start screen sharing.
Using the same computer with the same settings I can connect to some systems, but most systems won't allow me to connect.
In all cases, Enable Screen Sharing is checked. All systems are running iChat 4.x. All systems are running the same operating system. All systems are connected via hard-wire Ethernet.
What do I need to do to get iChat screen sharing to work? Connection Doctor does not show any results until AFTER a session has started.
We are able to connect via messaging with no problems.
Thanks,
Larry

Hi,
Welcome to the  Discussions
The Connection Doctor gives a shortened form of the Error message.
The Pop up (Send to Apple) has a Reveal Triangle next to the word Details.
In here will be a Longer Log with the Error code number at the end of the first main paragraph.
The Main issue with Screen Sharing is that it uses a Random port.
iChat uses 20 ports at iChat 4 and 5
Port 5190
On TCP (to Login to AIM) and to Plain IMs and ON UDP to send Direct IMs including File Sending and Pics in Chats.
Some modems and routers cannot handle this dual use and we suggest changing the Login port to 443 (it helps with some Logging in issues and some Video chats)
Ports 5220, 5222, 5223 on TCP for Jabber and GoogleTalk Buddy Lists.
Ports 5297, 5298, 5353 on UDP and 5298 on TCP for Bonjour Buddy Lists.
Ports 5678 On UDP for Sending/Receiving the Visible Invite to A/V chats
Ports 16393-16402 On UDP (Ten Ports)
(iChat 2 and 3 uses a wider range of ports (2) that can be read here which is where the Jabber and Bonjour ports are listed)
See this Article for iChat 4 up which only lists the changes to the A/V ports
You will notice that the later Article does not mention Screen Sharing.
This tends to mean you cannot "Set" the port in Port Forwarding due to it's random nature.
This may mean your Buddies do not have the port "open" for it.
Using UPnP which gives control to the App about which ports (and when) are opened.
There is also and Issue in Leopard with iChat 4.x with Internet Sharing (System Preferences > Sharing).
This can not be On. It effects all chats that involve A/V, which includes the Audio Chat with Screen Sharing.

Screen sharing doesn't work without a gateway

I'm back from a short trip and find that my gateway died in the meantime.
I have a LAN with quite a few Macs, some of them being Mac minis used as servers with no attached screens.
I can't use screen sharing anymore on my LAN to control any Mac that has not been set up to use my failover gateway. Only the Macs whose network set up has been changed to fully use the failover gateway can be controled. Unfortunately, this gateway and has limitations not allowing me to use it with every Mac/iPad etc. here. If I set up a Mac to use the failover gateway, but with no internet access allowed, that Mac remains uncontrolable with screen sharing.
So I'd like someone more experienced to answer these questions:
- How is it that an operational gateway with a working internet access is mandatory for LAN screen sharing ?
- Are authentication services responsible for the troubles here ?
Help would be greatly appreciated,
JM

While I understand the terms, I do not yet fully understand what your IP network looks like.
By "usual gateway", are you referring to a hardware device — commonly called a "gateway router" — that's been replaced here, or to the IP gateway settings present within most (all?) hosts on an IP network?
IP needs a gateway for traffic outside of the subnet. That commonly includes DNS traffic, either from the DNS server(s) on your LAN, or for IP hosts that are communicating more directly. This can also include determining the source of in-bound IP traffic, as that involves DNS translations.
Swapping gateway routers can also sometimes require flushing the ARP caches, depending on what hardware and software is involved. (Normally the new device will broadcast that on the LAN and thus update the caches, but sometimes things get a little wonky.) This if it's at the same address. If it's at different addresses, then the DHCP server, DHCP clients and static-addressed hosts all need to be updated.
In general (and because I'm not certain of your configuration), I prefer to avoid using Macs as IP routers, as they're expensive for and comparatively clumsy at that task. I prefer to use dedicated devices for that, and often preferanly including an embedded VPN server as I'd mentioned earlier.
Again, I'm not clear about your configuration, so the above might not address your question.

Screen Sharing Doesn't Work (Leopard to Leopard)

Does anyone know which things to click on in System Preferences to make Screen Sharing work? We've tried multiple ways but no luck as of yet. Should it be an Administrator? Is Allowing All Users a good thing? Once allowed, can people access EVERYTHING, including software programs and hidden files & folders etc.
So which way is the best way to at least make it work for now, and then... which is best for security purposes further down the road?
Cheers!

And a similar message on my MacBook Pro

same here on a 2010 macbook pro. i routinely use screen sharing to access that MBP from a 2010 mac pro. but ever since installing lion on the MBP (now 10.7.1), i'm asked for my "Kerberos password" -- and i've never even heard of such a thing.
so far, googling this has not led to anything helpful.
i love my macs, but stuff like this that impedes our productivity is a monumental drag (to say the least).

Screen saver no longer working after Lion upgrade.

Hi,
After standard upgrade about 2 weeks ago (mid July 2012) the screen saver no longer works. I mean I can certainly access the application and the desktop can be made to cycle through different photos etc. But when I configure the screen saver it just refuses to go into screen saver mode at all.
I'm not seeing too much occurance of this through the postings which is a bit worrisome as I'd thought this would be a much wider issue.
Cheers,
Herbie

Screen Sharing slows down dramatically after RDP upgrade from 2 to 3

For some reason once we upgraded from RDP 2 to RDP 3 our Screen Sharing has gotten increasingly slow. We are using it in a school environment where the teacher will share their screen with the students, and as we add more students to the share the sharing slows down to become unusable. This problem is intermittent (otherwise I would go though the logs and run a control test), and has only started upon upgrading to RDP 3. Anyone else experience this behavior? I believe we are all running 10.5.x on the OS side.

I also know someone that is having this issue; it was fine with the previous ARD version they were using in the computer lab, but after upgrading screen sharing have slowed down. It's not really that of an issue when its just one computer, but when they put all 30 computers the FPS drops down.
Keep in mind that they were not having the issues before upgrading. I've also been told that, currently, they got a 5 MB connection. I ran a network test and everything seemed fine (or more like I didn't know what was going to tell me that something was wrong, but all the numbers were very low).

Why the wifi doesn't work after the upgrade to iOS 5?

The problem is that after the upgrade to iOS 5 the wifi doesn't work. I mean, iPad is connected to the wifi but not to the internet and also the connection on the other device doesn't work. So I had to turn off the router and then turn it on.

Try a hard reset first to see if that does any good. To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
If no luck with that, you'll need to manually connect your iPod to your iTUnes library in recovery mode using the instructions in the Apple support document below. Doing so will allow you to bypass the passcode and restore the iPod.
