Screen sharing in Lion question

I am trying to set up screen sharing in my local network.
I am using a MacBook with latest Lion as server to which I am trying to connect.
I am connecting with a Powerbook 12" 10.5.8 without problems and controlling the MacBook via Screen Sharing.
I am unable to connect to the MacBook using a MacBook Pro with same Lion installed.
Before that I used the same setup to try out RealVNC. Again, the Powerbook connected to the MacBook without problems, but the MacBook Pro is unable to connect.
Any suggestions?
Thanks.
Oops, posted in wrong forum. Will try under Lion. Sorry.

This works like a charm!
I was also able to input the account password and make it work. Don't know what I did, but it is now working in Mocha. I like VNC Viewer too, but sometimes I am able to input the password and sometimes I can't.
Thanks.

How do I activate the Multi-Screen Sharing in Lion?

Hi,
How do I activate the Multi-Screen Sharing in Lion? I was told it was on by default but when my partner logs in from his machine, I can't also login to the actual Mac itself. When I first enabled Sharing it allowed him to connect even though I was already logged in but it was very sluggish and eventually the whole system crashed.
Any help would be appreciated.

Found it!
Make sure you have multiple desktops already running.
Go to System Preferences->Keyboard
Choose Keyboard Shortcuts
On the left select Mission Control. On the right, I have "Switch to Desktop 1, Switch to Desktop 2, etc"
On my iMac they were checked, and working.
On my MacBook they were unchecked. Checked the boxes, now it works.

Screen sharing between Lion and Snow Leopard

Does anyone know whether it is possible to do Screen Sharing between two Macs where one is using lion and the other Snow Leopard? I use this feature to help my father with his computer problems but am wary about upgrading my machine to Lion without an assurance that it will work across OS's. He is in Europe where I believe Lion a) may not yet have been released and b) think it unlikely anyway that I will be able to encourage him to change something he is already finding difficult (aged 84) having never had to use a computer prior to 3 years ago at my behest.

after reading your post, i thought i'd do the same on my lion machine -- toggle screen sharing off and back on -- only to discover that it was *already* off, although it was positively enabled on the same machine when running snow leopard.
i never disabled it, as i use the feature quite regularly, which is why it never occurred to me to check the sharing settings, because i always leave screen sharing on. but apparently installing lion either caused the setting to revert, or it's possible lion simply installs with screen-sharing off by default. (who knows.)
regardless -- a simple fix.
thanks.

Is it possible to use screen sharing between lion and mountain lion

I could always use screen sharing between my 2010 macbook and my 2007 macmini,both with lion.But now since I upgraded the macbook to mountain loin it doesn't work.The macmini did at first show up on the macbook finder sidebar under sharing like it always had done but as soon as I tried to connect the sharing option disappeared and won't come back.The macmini can still see the macbook however,its on the finder there.But when I try to connect from the mini to the macbook I get an error message that says something like "server error" and contact administrator(that's me!)I can't upgrade the mini to mountain lion as it's too old.So it this an incompatibility between the two operating systems or is it something else?
I also tried to do it with BackTo My Mac,enabled through icloud on both computers but no luck,not even showing the Back to my Mac icon on either Finder sidebar like it's supposed to.When I did it through system preferences-icloud,it said this was successfully enabled but it just doesn't work at all.
Cross about this since I always use the macbook to control the macmini which is plugged into a flat screen tv and it's much easier than fiddling around with a mouse and keyboard.

I can screen share my wife's Lion iMac using Mountain Lion and the reverse is true. If the computer is not showing up to be selected under shard on the left column of the finder it is probable a connection issue. I would check my home network, restart the the macs and toggle the sharded settings and energy saving settings like wake for network activity. Be sure and set up iCloud on both your macs and turn on UPnP if you have a router for your home network serving up NAT IP Numbers. UPnG will make the port forwarding enteries in you router to allow you macs to connect behind the firewall created by nat addressing.
I am currently having a problem with back to my mac. S
creen shares great the the Lion iMac but Mountain Lion to Mountain on one computer will not connect if the computer is sleeping. It lights the screen on the sleeping computer but never shows on the computer requesting to share. File share always workd. If I wake the computere before I attemp the connection, screen share work as it should. If I try to screen share while the second computer is sleeping, It will never work again until I restart the iMac.

Screen Sharing in Lion from iPad

Hello!
I am using 10.7.0 Lion now and when I had 10.6.8 installed (or when booting from the back up) I was able to see my screen from my iPad using Mocha VNC or VNC Viewer.
Now, when I open my mini from the iPad I get a login page, but I can't do anything, I can't type a password or click on the account. This is using Screen Sharing from Preferences.
If I use a server app like Real VNC, I get a black screen on the iPad, but I can move the mouse around and click anywhere I like, but with a black screen.
I am aware that screen sharing has changed in Lion, I can now log on any account on the Mac, but it is not working from the iPad (using Mocha VNC or VNC Viewer).
Can somebody help me? I use this feature every day.
Wilfredo.

Is there a way to switch to single-user mode for screen sharing in Lion?

Hello,
with the new multiple user mode one screen sharing guest can not see the mouse cursor of another - even if they use the same login.
It's a pity, because we use screensharing to discuss the content of the screens with multiple screen sharing users.
It is necessary to point with the cursor to show the other members of this 'screen sharing meeting' things while discussing.
This is not possible anymore with Lion and multi user screen sharing.
Does anybody know a patch or terminal command to switch back to single user mode for screen sharing?
Kind regards
Carl M.

Screen Sharing between Lion and SL?

I was about to purchase the new Mini Server but saw that it has Lion pre-installed. So I assume it won't run under Snow Leopard, which would have been my preference. As my other machines are all running SL and having no plans to change this soon, I am wondering of screen sharing would work between my MacPro (OS 10.6.8) and the Mini (OS 10.7).
Does anybody have experience with such a setup?
Thanks.

I will try it and see later but it will be this evening, (about 10 hours from now). FYI, mine are both all but standard Macs on a standard network. The Pro is wired the mini wireless. I have nothing like Remote Desktop installed.
If I don't reply, send me a message later. I may have forgotten.

Lion screen sharing breaks mouse for local user.

I think I've discovered a bug. I have a new iMac 27" on 10.7.2 and a MBP on 10.7.2. The iMac has two accounts created, mine is the administrator, my girlfriends account is standard user. She likes to use the iMac with the bigger screen so I retreat to the MBP and use screen sharing to continue working on my documents that are under may account.
The problem is that the mouse will stop working for my girlfrends account when I have Screen Sharing running. Her mouse becomes unresponsive and just jumps around the screen once in a while. As soon as I close Screen Sharing her mouse returns to normal behavior.
Has anyone heard of this?
I tried creating another standard account as a test, same problem.
Thanks,
Ron

10 days with no ideas = apple's new screen sharing in lion is broken.

Screen Sharing Not Working in Lion

I cannot enter into remote systems via screen sharing since Lion upgrade.
Some basics
remote systems are 10.6 with screen sharing on. (same as last week)
I'm on the same vlan with no restrictions, and yes I can ping them.
I can open screen sharing, and authenticate as the remote's admin user, but it hangs on connection.
I've got 12 Xserves and 50+ MacPros on 10.6 and had / have no issues connecting to those when I'm connecting from 10.6.
I havent yet looked at the logs of the remote units, but I'm guessing this is a solid 10.6 vs 10.7 incompatibility. I'm begining to configure some Lion machines and want to be able to admin those as well as my 10.6 gear, (hopefully from one machine).
ANYONE ELSE WITH THE SAME ISSUE (OR NOT HAVING THIS ISSUE) WITH SIMILAR CONFIG?
T.I.A.

So some more info.
Now that I have a few Lion machines running Lion to Lion screen scharing works fine.
Sorry for the all caps before.
I do like the vitual desktop vs real desktop. In windows the whole virtual desktop does have it's drawbacks. But hey it's only windows.

How do I get started with screen sharing?

There are dozens of articles on the web and posts here talking about what's new with screen sharing in Lion, but for the life of me I can't find anything that tells somebody completely new to screen sharing how to get started. If I want to do screen sharing with a friend (over the Internet, not a LAN), what exactly do we have to do to get started?
Sorry for a noob question, but everything I see assumes you're already completely familiar with it and just want to see Lion tweaks.

ok so go to your system preferences on your MAC > go to sharing > click the screen sharing option on> next go to the add users section right below on the right and you add your friend whom you want to share with. You have to select a password for this person. When you get this done you will see a
Other users can access your computer's screen at:
and you will have an address there with some numbers. give this to your friend whom you want to see your screen, they have to post this in their web-browser, and that is how you remotely screen share. This is if you all are not on the same network. Also if you want to share his/her screen they will have to do these steps for you.

Screen sharing Mac and PC?

I am on a LAN and i want to know if you could share the Mac's screen with another PC. If the macbookpro is ON and opened up could i control or see its screen from another PC o the network? If yes, how?

OSX's Screen Sharing is based on the VNC protocol. So on paper, any VNC client should work. In reality, some VNC clients work better than others. And the way Apple implemented Screen Sharing in Lion "broke" some of the PC VNC clients. So try a several different VNC client on your PC to see which works best for you.
Me personally, I still use the original AT&T VNC client, which is really old, hasn't been updated in years (but still works on Windows 7,) and doesn't have many features that have been added on by other vendors. But that lack of add-ons I belive are why I seem to have very few problems with connecting from my Windows PC. YMMV, of course.

Screen sharing across internet

I had set up my Mac for screen sharing with Lion and was able to share the screen to another Mac on the local network, or VNC across the internet. Upgraded to Mountain Lion and screen sharing continued to work both locally and remote.
Moved to Mavericks and now the screen sharing works locally, but will only work for about 30 minutes across the internet. If I reboot the Mac, then I can access the screen across the internet for about 30 minutes, then the connection drops and I would have to reboot the Mac again.
I have screen sharing turned on by:
System Preferences -> Sharing -> Screen Sharing. Clicked on 'Computer Settings...' and checked 'VNC viewers can connect...' and gave it a password.
I can access this remote Mac across the internet using either JollysFastVNC, or the screen sharing app via Finder. Turns out that remote command line and Finder also can access this machine for about 30 minutes, then connection drops.
Has anybody else seen this problem, or have any suggestions on what I can try to keep remote access working for more than 30 minutes?

I don't have a solution (yet). I have the same problem with a Mac Mini remotely. After some short length of time, my ability to control remotely vaporizes. The Mini is running 10.9.1. It seemed to work ok earlier - although the previous version of Mavericks kept screen sharing from working if the firewall was enabled at all. The last system update from Apple fixed that.
But this isn't universal. I can connect with LogMeIn to the Mini after a fresh reboot, but eventually (30 min?) all I get is a black screen. I can connect with LogMeIn to a MacBook Pro on the same remote network as the Mini and it works just fine. I can even connect with LogMeIn to the MacBook Pro and then do screen sharing to the Mini on the same remote network - until that 30 minute? window has elapsed, and then screen sharing fails to connect without even telling me it failed (no black screen, no alert, nothing). Then that doesn't work either. File sharing from that MacBook Pro to the Mini on the same remote network continues to work, and server applications continue running fine on the Mini. For some reason the only problem is that I can't *see* the remote Mini on 10.9.1 for more than a short period after a reboot. All 3 computers involved are running 10.9.1, but only one (the Mini) is failing like this.
It sounds like the problem you are having. If I figure anything else out I'll let you know.

How do I switch remote desktops with lion server screen sharing?

When I sometimes use the Lion Server screen sharing feature to take over my iMac using my Macbook, I find that I'm not able to switch desktops on the remote computer, i.e. using the three finger swipe.
Both are running the latest versions of Lion Server.
Now there MUST be some way to do that right?
Who knows?

Hi John, perhaps I did not express myself clearly.
My desktop iMac is set up with multiple desktops (desktop 1 for system stuff, desktop 2 for mail, messages, skype etc, desktop 3 for Safari and desktop 4 for text proessing, VM-Ware and other work).
When I work on that machine I'm logged in as one user and use the three finger swipe left and right or the Cmd-1 thru Cmd-4 keys to switch between those desktops.
I haven't founf how to do that from my a remotely connected MacBook Pro.
Both of which are running Mountain Lion in the mean time. The iMac runs Mountain Lion Server and the MBP has ML Server installed as well, but nut implemented. Just to be able to use the remote screen...
Hope this makes my question a bit mre clear...

Lion Server Screen Sharing for Adminstrator

I'm having difficulty using my Administrator account for remote screen sharing after the upgrade to Lion Server. All other remote access tools work (Server Admin, SSH, file sharing, etc.). I'm also using LogMeIn to get to the server and, if I make an adjustment to standard user account to allow for server administration that account can use screen sharing with no problems. Only my administrator account does not seem to work. Has anyone else seen this?

This thought just occurred to me. Do you have the Macbook Pro Firewall enabled? System Preferences -> Security & Privacy -> Firewall. Is it enabled? If it is, try disabling it.
Time to ask a question about your network setup. Wild Goose Chase questions.
You mentioned an Airport Extreme. Is that the ONLY router in the house? The reason I ask, is that if you have multiple WiFi routers (for example because your house is so large, you need more than one WiFi router to cover the entire house, or your house has has 4 floors you need to cover and the structure interferes betwen the basement to the converted attic), you could have multiple subnets which could affect the ability to connect to devices on the other subnet. If you do have multiple subnets, there are ways to address this.
I would like you to download and run "Bonjour Browser"
<http://www.macupdate.com/app/mac/13388/bonjour-browser>
Run Bonjour Browser on the Macbook Pro (and any other Macs you like). I want you to look for "Remote Frame Buffer" entries (VNC Servers - aka Screen Sharing servers). Click the triangle to show all the systems offering VNC server.
Assuming you see your Macbook listed, click on its triangle to show the IP address and port number. It should be something like 10.0.1.nn:5900. Hopefully you see the same IP address as you think your Macbook has assigned to it (which you can see via Macbook -> System Preferences -> Network -> Advanced -> TCP/IP.
If you are not seeing your Macbook via Bonjour Browser from your Macbook Pro, then there is something affecting your ablity to see the Macbook.
