Turning on Screen Sharing Remotely

In an effort to try to get Back to My Mac working, I read I had to turn off Remote Management and instead use Screen Sharing. I'm traveling right now, so in a completely boneheaded move, I used VNC to turn off Remote Management and wouldn't you know it - it's instantaneous. It knocked me off VNC so I couldn't turn on Screen Sharing. Is there any way to turn Screen Sharing on through the terminal command line? Or even turn VNCserver on temporarily so I can do this through the GUI?

Also, before copying files to server make sure ARD is turned off and will not start at boot:
(From running '/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/ kickstart -help')
- Stop the Remote Management service and deactivate it so it will not start after the next computer restart.
*/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -deactivate -stop*

After Clean Install of Yosemite, Screen Sharing & Remote Login are turned on in Sharing preferences

Do you guys know if this is a bug?
I created a custom USB Yosemite installer using the 'createinstallmedia' binary inside the Yosemite installer.
Booted iMac with this USB installer and proceeded to install Yosemite (fresh formatted drive). No problems.
When I log in however, and check the Sharing PreferencePane, both Screen Sharing and Remote Login are turned on.
I've tried this multiple times (repartitioning the drive each time and I have created the installer media twice).
I'm posting this I guess more as a report as the solution is simple enough (uncheck these services).
But it's definitely a security risk.

Just 2 minutes before I received your reply I solved the problem. I have been running a software firewall (DoorStop X) on the Mac Pro. It turns out that I had not allowed traffic over two ports necessary for Home Sharing– port 3689 and udp port 5353. When I corrected this everything is back to normal.
I did the clean install because I've been having intermittent problems with several apps including Compressor, Safari, and to a lesser extent FCP. I've been contemplating doing this for several months because of all the garbage that has collected on my system over several years since I last started from scratch. I have a bad habit of installing things that add kext files and otherwise modify the OS. I decided to get rid of all that stuff. I'm glad I did. All the problems I was having seem to have resolved. Safari runs 3x faster than it ever has. And I no longer have the headaches that Compressor was giving me. I think I'll take better care of my system from now on.

Turn off screen sharing

Hi. I work for a school district and we use ARD to monitor student screens. The problem is that the students can screen share with each other. We need to be able to completely disable screen sharing between these students while still being able to use ARD. Because it is a high school the maintenance students know the passwords so we can't just disable it. We just need to stop the students from cheating. Thanks for the help.

Are you letting the students use the computers with administration privileges? That should be a major "no no"
If you lock "Sharing" how can they turn it on???

How can I remotely enable Screen Sharing remotely on 10.8?

Is there a way to remotely enable Screen Sharing from another mac? I'm using 10.8.

I assume you mean by remote login.
To enable via SSH to an admin account:
sudo launchctl load -F /System/Library/LaunchDaemons/com.apple.screensharing.plist
To disable:
sudo launchctl remove com.apple.screensharing

Screen Sharing/Remote Mgmt Recommendations... Timbuktu, ARD, Bomgar...?

Can you recommend a Screen Sharing and/or Remote Management solution to be used for remote support? I will need to connect with remote networks and control computers via Screen Sharing... Traditionally, I have used Timbuktu for remote support which allows me to pass through routers using NAT and to directly address any computer that's configured properly. Recently, I've started to use OSX's built-in Screen Sharing ability over the web as well. However with the latter option, there is no easy way (that I've found) to address unique computers behind NAT?
Some solutions that I'm looking into:
1) Timbuktu. A proven solution.... a little expensive (if we had no upgrade path), requires router port-forwarding....
     http://www.netopia.com/software/products/tb2/index.html
2) Bomgar. A recent client, had new Windows hardware installed and the company that installed the system was using Bomgar for remote management. It's suppose to be an enterprise level solution but that's all I know....
     http://www.bomgar.com/
3) Apple Remote Desktop (ARD). This was $300 bit it's only $80 now for an unlimited license. Of course it's Mac only and seemingly low-priority for Apple and it may a little over-kill on the reports and management side. Creating installer packages seems unnecessarily complex when each client machine seems able to manage itself in terms of Software Update. Also, I don't see where this product can get past NAT. So, this could be an issue. Some people mention that establishing a VPN is the answer to that equation but I'm looking for simplicity too.
     http://www.apple.com/remotedesktop/
4) LogMeIn. I have not used.... the Pro version is too much at $70 per computer per year.... but the Free one is.... FREE!
     https://secure.logmein.com/products/free/
5) TeamViewer. I have used this a few times and it seemed to work as advertised.... This could be a compelling option.
     http://www.teamviewer.com/en/index.aspx
So, what remote access solutions do you use and recommend...?
Thanks,
Robert

If you are doing remote support professionally, you may also want to consider GoToMyPC (which also Works on Macs).
LogMeIn.com and TeamViewer.com Free options are only for personal use. If you are using them professionally, they they want you to pay.
Having covered my A..., I would say cross platform, TeamViewer.com is a good choice, as it gets through home routers, and provides file transfer (the Free LogMeIn.com does not provide file transfer). TeamViewer.com can also deal with corporate firewalls (assuming corporate does not block the service).
Another way to approach this might also be using Hamachi (another service from LogMeIn.com) which can be used to easily create a Virtual Private Network between your system and the destination (getting through home routers), then just use treat the system as if it was local, and use Screen Sharing, VNC, RDC, CoRD, etc... without worrying about home routers, and such. Can also do file sharing as if the system is local. Where local does assume the broadband connections have reasonable bandwidth.
As for myself, I only remotely maintain my Mom, and I set that up long before many of the current offerings, and did all the messy port forwarding things at Mom's house so I could use VNC over secure ssh tunnels. But if someone else in my family called asking for help, I would choose TeamViewer.com, as I think it would be the easiest for me to talk them through getting it up and running on their end.

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

Should be:
aptop:~ admin$ sudo scp -Epr /Users/[email protected]:/Users/iristestlocaluser

How can i turn off library sharing remotely because i cant remember all the computers or systems

I want to be able to add my new computer to my library sharing however it will not let me. It says i already have 5 computers on the system. My question is as i said, how if possible can I turn off the connection to the other computers?

This isssue is about authorisation rather than home sharing.
You can't de-authorise just the computers you no longer have access to.
Your only option is to de-authorise all your computers and then re-authorise those you wish to be authorised. You can do this by logging into your account settings in iTunes on your computer (Store > View My ID) and selecting the option to de-authorise all.
Please note however, you are only permitted to do this once in each 12 month period, therefore you would be better de-authorising your computers before you lose access to them. you can do this from the 'Store' menu in iTunes.

Need good screen sharing remote app like gotomypc

Not sure where this question belongs. I have trialed gotomypc and it is great with one exception. They do not support audio when using it for a mac to mac connection and I really need audio. So, what is the best application to use for remote computing?

Not sure if its the best, but I'm just checking out Logmein. They have a bunch of different solutions for remote access. For me, this one is the best - mostly because I can access my home mac from work on those rare occasions when I need to, but most of all - its free.

Screen Sharing turns itself off!

This is an issue that has turned up since moving to lion.
I have scren sharing enables in System Preferences > Sharing on my office mac and home mac. Sometimes I will try to screen share with one or the other mac and the Screen Sharing app will launch and just sit at the "Connecting to Home/Office Mac.." window for a while and then a Connection Failed window pops up telling me to enable screen sharing on the other mac.
When I get to the other mac, Screen sharing has been disabled and it wont allow me to re-enable it without restarting the computer. This same thing happens on both of my macs, so it doesn't seem to be an isolated incident. It happens fairly frequently.
Has anyone ever experienced this or have a solution?
Thanks

Try this on both machines and test to see if it works. If not, you may need to run an update if not done so already.
Open System Preferences > Sharing
Turn OFF Screen Sharing, Remote Login, Remote Management, and Remote Apple Events (just turn everything off)
Now turn ON Screen Sharing, Remote Login, Remote Management, and Remote Apple Events
Now turn everything OFF again. We have just "kickstarted" those services.
Now enable the services you want. If you just want to access your computer through VNC or screen sharing, just turn on Screen Sharing.

PLEASE HELP, SOMEONE REMOTELY VIEWING/SCREEN SHARING MY MACBOOK?

Hi - I urgently need help from anyone who knows about this issue - I am a very basic macbook user, and don't really know about all the different programmes etc. I believe someone ( the guy who sold me the macbook, who told me he was a mac repair person and programmer) has been hacking into the computer, using the remote access - there is a programmed called SCREEN SHARING but I cannot access it - and a bunch of other files such as odsagent etc - not sure if these indicate he is using the screen sharing/ remote access to my mac.
The reason that I believe he is accessing the mac, is that he downloaded all the files, so would clearly have access to passwords etc, there were loads of his old files, that showed pictures of people saying " target", and old files showing he was studying comuter/ mac programming. The first time I went online all of a sudden the computer froze, and two green lights showed on the num lock key and the shift key I think, the two keys were frozen, and the keyboard basically wouldnt respond, but the activity continued on the screen. This has happened a number of times since then, usually just randomly the keyboard freezes, and if you wait a while it goes back to normal - the mouse works fine, then one day it keep sort of freezing/ getting stuck/ pausing for no reason - the next day its fine again. He put in a load of software, which he has obviously been able to get round the need of liscening numbers, as he did not provide me with them. one day I saw a name "macbook pro" suddenly appear, and that it was tryin to connect/ share or something - this has never happened to me before with my old mac- it was like another computer was connecting/ sharing with my computer without my permission - this was when I was online. This has not happened since.
I am scared he is accessing the computer, because these things that happened, and because there is loads and loads of files and programmes, which sound suspicious, i dont know what they do, and I just have this dogey feeling about this guy, and the fact that there is screen viewing/ remote management files etc which I cant access, but I am not sure if they are being accessed.
PLEASE HELP - I FEEL LIKE MY PRIVACY IS BEING INVADED - I was speaking to my family on Skype and the green lights came on/ it froze, I continued with the conversation, but later I felt like he might have been watching.
If anyone can recommend an expert in the London area, that can check the mac to see there is nothing on there that is being used to remotely control/ screen share my mac, I would be very grateful - its just horrible using your computer, and always being worried someone is invading your privacy, and and downloading your files etc.
Sorry if I sould paranoid, but I have a strong feeling something is not right here.
Many thanks for your help in advance.

Since you don't know much about computers, disconnect your internet (wireless or wired) to prevent future unwanted access. While it is smart to contact Apple Communities, this is a criminal matter and you should consider taking the matter to the police. People like this will not stop with you. You need to list the private data that may be stolen and take action (cancel credit cards, change passwords, bank accounts, phone numbers, whatever you have cause to be worried about). If you can afford it, buy a new hard drive, remove the old one, and install OS X from scratch. Give your old hard drive to the cops. Make sure you turn the Firewall on (click the Apple up on the toolbar top left > System Preferences > Security) and uncheck any "Sharing" options (System Prefernces > Sharing). This event you are experiencing is unfortunate, and rare, but with a pro-active attitude you will come through it fine - and wiser.
EDIT
dgambler is right in that by purchasing a Snow Leopard disk (presuming you don't already have one) and performing a fresh install (it is easy) is a sure way to "take back" the controls of your Mac. You will need to study online tutorials for "wiping the drive" rather than a simple install. But you should let the police look at the hard drive before you do that - they will be able to see exactly what this person did.

HT1810 Screen sharing is currently being controlled by the remote management service

Can't access screen sharing

You''ll need to turn off Remote Management and turn on Screen Sharing in the Sharing system preference of the system to which you want access. This will stop management by Apple Remote Desktop, if you happen to be using that software.

Lion screen sharing over Internet

I'm having some issues setting up screen sharing. The problem is that I set it all up and can see the other computer when we are on the same network. But I cannot see the device when I'm back home and trying to screen share over the internet.
I need to be able to see the screen of my client's Mac while I am at home.
Here is what I've done to set up screen sharing:
Both Macs are running Lion 10.7.3
I have set myself up in the address book of the Mac I want to access.In my address book card I have multiple emails. One of them is the email that I use as my Apple ID.
I turned on screen sharing on the remote computer and added myself to the list of people able to screen share by selecting my address book card that includes my Apple ID.
Access is for all users
I have checked "Anyone can request permission to control screen."
On my computer I have ensured that my Apple ID is included in the Users and Groups control panel.
When I am on their network, in their home, I see their computer in the shared devices section of my Finder window.
I am able to request permission to screen share and am able to gain permission when they accept.
But when I get home, their computer does not show up in my Finder window under shared devices.
What critical step am I missing?
Thanks!

Yes, I didn't say Back to My Mac doesn't let you share the screen over the internet - it does. But it requires you to know the password of the iCloud account that is signed in on the client's computer, as I've said. Your client would be nuts to give you that password, as would you be to sign in your iCloud account on his/her machine. That's not an option.
Here's what Apple says about using Back to My Mac:

What ports do I need to open in a home router to support Screen Sharing?

I'm trying to support my 88 year-old dad who has totally messed up his iMac. We're both running 10.6.8. I went ahead and bought the Easy Remote Desktop app from the app store, since I don't need a heavy-duty admin tool, just to see and to remotely manipulate his screen. I tested it on my home LAN with my wife's computer and it works great. I did have to find out her IP address, and she did have to turn on Screen Sharing services open to just me first. The downside for Screen Sharing vs. Remote Administration is that there is no announcement that you're there.
So I'm thinking that I can just type in my dad's IP address. Of course he has a DSL router and probably has a DHCP address, so I found out about Dynamic DNS, and located a free Dynamic DNS service. I've already established (the functional equivalent of) a static IP for myself with this service, and I'm thinking the next step is to talk my dad through doing the same for himself. Then the next hurdle I think would be to talk him through opening the Screen Sharing service on his Mac, and to add me as a user. But the final hurdle I think would be to open inbound ports for Screen Sharing from my IP address. Since Screen Sharing is a native Mac OS function, I figure this is the place to ask that question. And to ask if I'm on the right track here...

Screen Sharing uses port 5900.
However, I'm going to suggest that you use TeamViewer.com as it will deal with all the networking issues much more easily and without needing to worry about opening ports in your router.

Messages Screen Sharing

Messages won't allow me to share my screen or to request to share someone else's. I'm tyring to do it with my wife's computer running 10.8 on a separate network and the option is greyed out in the dropdown. I've ensured that Screen Sharing is enabled within messages and in the system preferences "sharing" pane.
We are both running 10.8 and using iMessage. We were both able to before the upgrade.
Any suggestions?
Thanks for your help.

Hi,
That one is so good it's wrong needs modifying.
You do not have to have System Preferences > Screen Sharing Enable at all.
That is for a totally different app that is in the OS and can be activated from the Finder.
In the Finder > Go Menu > Go to Server
Type in VNC:// and then IP of a LAN based computer (Such as any Bonjour computer)
This will then Invoke the Screen Sharing App and link your with a VNC connection and show your their Desktop (if they accept).
You can do it to a Public IP (The modem of a contact) but they need to Forward the Port the VNC connection is On to their Computer.
This Process does use the Apple Remote Desktop engine the same as iChat/Messages does.
However iChat/Messages makes the connection using SIP (Session Initiation Protocol) which deals with the routing through the Modem and any router at the other end an adds a VNC connection Along side and Audio Only chat.
It should read like this:-
Additions in italics. Strike throughs for not needs action/text
• Go to your Apple Logo / System Preference / Sharing
• On the mac(s) that you would like to screen share , Turn on Screen Sharing. Allow Access / All Users Not needed
• Open iMessage app on your mac
• iChat Style Buddy Lists are not displayed in iMessage by default. You will notice that there is no Screen Sharing button on iMessage as it was on iChat. There is (a Button) on the Buddy lists.
• To activate it, go to the ‘Messages’ menu at the top menu bar and select Accounts and turn on ‘ Bonjour ‘
In fact Enable any Jabber or AIM valid Account It does not have to be just Bonjour
• Once you turn on Bonjour Any Enabled Account you will notice the Bonjour name shows up at the bottom left hand corner of the iMessage window.
• Now under the Window tab, click on "Buddies" or COMMAND + 1 ( number 1 )
• You will now see the an iChat Style Buddy list pop up but any Bonjour only list may be empty.
This List is a combined list at present.
Go to Mesages Menu > Preferences > General Section and untick the line about "gathering all accounts"
• If you have not added an AIM or Jabber based Account do this:-
Messages menu again and under Preferences, go into ACCOUNTs and click on the + at the bottom corner and add an AIM or Jabber account .
Note : you will need an AIM/Jabber/Google account ( just like you did on iChat before )
• Once you log in successfully, You’ll notice your list appears and you’ll see the familiar Screen Share button located at the bottom centre of the Buddy List window.
Now go to the Video Menu and Enable Screen Sharing at your end.
Text you Buddy that is using AIM Screen Names or a Jabber/Google/Facebook ID on iChat or Messages and get them to enable Screen Sharing as well.
To activate, simply click on it and it will send them a request.
Alternatively Highlight the Buddy and use the Buddies Menu
Alternatively to that Right click the Buddy and use the Contextual Menu.
NOTE:-
Screen Sharing like Audio Only chats and Video Chats is AIM to AIM (including Valid Apple ID options) or Jabber to Jabber (which includes GoogleTalk and Facebook IDs) using iChat or Messages on both computers.

Hi,
So iChat 5
Which increment versions ? (if Updated)
Snow Leopard.
Update to ?
Exactly what is "Fast Bandwidth" where you are ?
In iChat, in the Video menu, have you turned On Screen Sharing ?
In your routing device have you used UPnP to open the ports iChat uses ?
Do you get any error message ?
Does the Connection Doctor say anything in the Errors tab ?
Do you get the Pop up to Send to Apple (Or not) ?
My ageing MacBook Pro of only 3 years of age can also Screen Share
Sometimes I even let it do it to the 8 and 1/2 year old G4/Dual 1Ghz
Your reason for telling me your 2) is to Say "I have the Latest and Greatest, so it should work".
My Reason for telling people my G4 can do it is to say "It can be run on anything above a G4/1Ghz Dual processor, so it's not the Mac or the App"
Notes.
iChat 4 and 5 use 20 ports to do various bits.
One of these, that is used during Screen Sharing is Random. Only UPnP will get around this. (Or Port Mapping Protocol on a Apple Base Station).
My Internet Connection is 8Mbps down (I get about 7.25) and 780 up (I get about 700) and this is average here.
24Mbps both up and down is about top of the Range. 8Mbps down and 500 up is more common.
In Australia anything faster than 128kbps outside of a major town is considered fast.
What is the internet speed like in Utah ?
Are we talking a town or somewhere a bit more remote ?
Re 5)
It's nice that you rate Steve jobs with 3 stars (I presume there are only three stars in your rating system). I don't see what that has to do with Screen Sharing though.
