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.

TS2972 is it possible to use home sharing between two users on the same computer?

My wife and I have itunes accounts and want to be able to share music we have each bought on our accounts. We have tried setting up the home sharing on our PC but it doesn't show up on the screen. Can anyone please help?

"Is it possible to use home sharing between two users on the same computer?"
No. Home sharing is used to connect two running instances of iTunes across a network. When you switch users on the computer all applications running on the other profile are suspended.
You can however share your respective media folders so that they are visible in either profile and then copy over any content that you want, or you could create a single joint library which you use when either user is logged in.

Asking for permission when screen sharing between MBP and Mini?

Hi Guys,
Like many others I have a mini connected to the TV, and use that as my media center, all music, movie, pictures, etc. is shown thrue the mini.
After upgrading to Lion I cannot use screen sharing as before, where I just connected to the mini, and voila I had the full control. Now it seems I have to accept the screen sharing request!?!? Is there a way around this, I surely hope so, because otherwise it will defeat the purpose of my mini! I mean, I have no mouse or keyboard attached to it obviously!
I hope there is an answer to this
Best regards
Viktor

Viktorrrrr,
It appears that Screen Sharing is a bit "buggy" in this first release of Lion.
Having said that, I have managed to get mine working and it is possible to have screen sharing without the approval prompt - the key is that you need to connect using the same account that is already logged on at the machine you're connecting to. So, in your case, after you click "Share Screen..." on your MBP, you should enter the account name and password that matches the account currently logged on your Mac Mini.
This should be fine if the account currently logged on your Mac Mini is allowed to do Screen Sharing (see the list of users in the "Allow access for:" section of the "Sharing--->Screen Sharing" system prefs).
If this works for you, stop reading here!
However, if (like me) you log on locally to your Mac Mini with a Standard account, but only allow Administrators to connect to the Mac Mini via Screen Sharing, then you have some extra work to do because, as you know, when you connect via Screen Sharing with one account in order to view the screen of another logged-on account on the Mac Mini, you get the prompt asking for permission. There does not appear to be an option to switch off this behaviour and, I suspect, this behaviour will remain due to privacy/security issues. So, if you want to avoid this prompt, you are going to have to log in using the same account. And to do this, you will need to allow this account to Screen Share.
The quick way to enable this would be to choose the option to "Allow access for: All users" on your Mac Mini - this would then allow your account (and ALL others!) to connect via Screen Sharing. But you really don't want to enable this if you can help it. Much better, would be to create a new local group on your Mac Mini called something like "Screen Share" and populate this group with all the accounts you want to be allowed to connect via Screen Sharing.
To create and populate a new group:-
Go to the "Users & Groups" system pref and click the + below the list of users to bring up the "New Account" window. Where you see the pull-down menu that says "Standard", click on this and select "Group". Enter your new group name and click "Create Group". The new group will be created and you can then select the accounts you want to include in this group (ie. the accounts you want to allow to connect via Screen Sharing) in the "Membership" section - just tick the boxes of the ones you want.
Now go back to the "Sharing-->Screen Sharing" system pref. Where it says "Allow access for:", click the "Only these users:". Now click the + below the list to bring up a window of all users. Make sure "Users & Groups" is selected in the left pane, then click on your newly-created group in the right pane and click "Select".
Sadly, this is where the real bugs seem to be!! When I try to permission my group for access, more often than not, my selected group is not added to the list of allowed access. I have played with this for hours, clicking various options in various sequences, but have not found a pattern. Even when my selected group does get added successfully, I sometimes find access is still not granted to that group and its members!!
I'm afraid it seems to be trial and error at the moment - I guess a fix will come eventually, but for now you just need to keep adding the group, removing it, turning Screen Sharing on then off then on again, try adding again...etc! I CAN tell you that I did eventually get my group to stick and work as intended, so it is possible...but it will take time!
Sorry for the lengthy response. Good luck!

The difference between Lion and Mountain Lion

Can some one explain to me the difference between Lion and Mtn Lion? I'm currently 10.6.8 Is it beneficiall for me to upgrade?

Mountain Lion is an enhanced version of previous OS X and so that is Mavericks.
About upgrading it all depends on what your needs are and if your hardware supports it.

Please check also applications compatibility. From Lion onward, you cannot run PPC application.

Can I use iWeb with Lion and Mountain Lion

Yes.
But the app was discontinued years ago.

Screen sharing between server and iMac appears to connect but no window opens

We have been trying to screen share between a server and iMac. Both are running Snow Leopard 10.6.7. It seems like we connect using the share screen app because we don't get any error messages after inputing the username and password but no window opens for the server we are connected to. When I look under the windows tab I can see a checkmark next to our server name and trying 'bring all to front' doesn't do anything. The video card on the server died and was removed by our tech support who said we could still access the computer via screen sharing. Would the server not having a video card be the cause of our problem?
Thanks.

Hi,
A Bit for other reading this thread.
To change the Login port for any AIM based name you have to obviously Log out first and then Change the port (SSL might need to be selected first) and then Press Enter to "Set" the port.
This use of the Enter key is the bit that is different to earlier versions of iChat.
For Gary,
Which Thomson-Alcatel device do you have ?
Thomson-Alcatel Speedtouches used to work well when the firmware that ran them was at Version 4.2.5 or less.
At least at this level you could access the device via Terminal using Telnet and then access the Command Line Interface (CLI) and "Unbind" SIP from port 5060
Later versions of their Firmware did not allow for a full Unbind of SIP and Video and Audio chats could only be partially successful (about 15 buddies out a list of 50
Of course using UPnP to open ports for iChat 4 helps with the Screen Sharing as the process is an Screen Share with an Audio Chat along side and both have to work/connect.
I am surprised to hear that in iChat 5 that Screen Sharing is not working when Video and Audio chats are.
For this reason I would ask how the ports have been opened in the Thomson device ?
After that I would keen to know if the Thomson Device or the Time Capsule is doing DHCP to the LAN ?
(Share an IP on the Time capsule is to Enable DHCP)
I am not sure how AT&T expect anyone to use their site to gain help or see what they currently offer when you have to type in a phone number or area (ZIP code).
I did enter the example number and got to this set of pages http://www.att.com/esupport/main.jsp?cv=801#
I see no reference to any Thomson-Alcatel device.

Screen sharing between SnowLeo and Leo?

I have a G5 with 10.5.8 and the rest of my computers are all Intel based.
If I upgrade to SnowLeopard would I be able to use the screen sharing feature with my 10.5.8 G5?
Thank you.

If it works now across those machines, it will continue to work for the foreseeable future.

No screen sharing between Leopard and Snow Leopard

A buddy just bought a new 27 inch iMac after the screen on his old iMac (running Leopard) died. We had no problems screen sharing when he was using the old Mac, but with the new iMac running Snow Leopard, he can screen share with me but I can't screen share with him....at least, iChat says I am sharing my screen with him, but he can't see anything. It must be an issue with Snow Leopard, since when he opened iChat on his MacBook running 10.5, he was immediately able to view my screen.
Any thoughts, anyone? Cheers!!!

Networking/screen sharing between Mac and PC

I have a standard home wired/wireless network using a DHCP router. My main computer is a Mac Pro running Snow Leopard (latest everything). My secondary computer is a Windows 7 PC, which has IP address 192.168.2.94.
On the Mac Pro, in the Finder sidebar, under shared, I do see the PC: it's called "rackpc". If I click on it, I see the option to Connect As, but if I click it, it says Connection Failed (the server "rackpc" may not exist or it is unavailable at this time). The screen sharing button doesn't appear (as it does for other Macs in my network).
However, if I manually use the Finder's command-K (connect to server) and type in vnc://192.168.2.94, I can easily connect to the PC and share its screen.
So my question is: how can I "save" this bookmark of vnc://192.168.2.94 (or better yet, make the Mac auto-sense the rackpc's existence, which it partially does) and allow it to appear properly in the Shared list of servers on my local network? Right now it appears there, but as I said above, Connect As doesn't work, and Screen Sharing doesn't appear.
The rackpc is not on a fixed IP because I can't figure out how to do that in Windows. So it's grabbing .94 from the router, which is fine by me for now.

ITunes 9 - Using 'Home Sharing' between Windows and Mac libraries

I have my main iTunes music library stored on my Windows 7 PC. It is currently around 200Gb in size, so pretty large.
I want to be able to use 'Home Sharing' in iTunes 9 to access this library on my Macbook over my home wireless network.
I don't, however, want to copy the music files themselves over to this laptop, but simply access the library over the network, and play them via either iTunes 9 or Front Row.
I would appear that the Windows and Mac 'iTunes Library' xml files are incompatible. I can't 'Alias' the Windows library on the MacBook for this reason. Does 'Home Sharing' eliminate this problem? Is there a way of accessing the library on the Windows PC without copying all of the files over to the MacBook?
I want to maintain a single library (which is often changing with new podcasts etc), rather than 2 libraries which I have to keep in sync.
Does anybody have any ideas on this one? I'm sure I am not alone in having this problem.
Here's hoping...:)

Screen sharing from iChat with Mountain Lion

I have not upgraded yet. I want to, but I am concerned that I will no longer have the ability to screen shard with my parents out of state.
I utilize iChat to control my parents computer, they live out of state and are not too computer savvy, this has been a life saver for me. Does Mountain Lion have a feature like this or is it gone with iChat? Is there a video chat option, or am I stuck with facetime???

Hi,
Yes.
You have to use the same iChat ID as you do now. (AIM or Jabber based)
You have to (it's just easier) have the Buddy lists on View (by default they are not)
Yahoo was added for iChat 6 and is in Messages but does not do A/V chats
iMessage (the new Apple Services between Apple iOS devices and Macs with Mountain Lion) is also Text only.
You have to be able to do A/V Chats.
Speed-wise over the Internet this has to at least 128kbps (the same as a Video Chat on a 1-1 basis)
Another way to view this is that Messages is iChat with the iMessages ability shoehorned in and with a main interface change.
When you first start up Messages it tends to push you to enter an Apple ID to "register it" for the iMessage service.
If you migrate an older OS's User Account to the computer the System Preferences > Mail, Contacts and Calendars (New Preference Pane) picks up on email and other IDs which tends to mean they get added to Messages for you.
You can of course add Screen Names and IDs using the + Button in Messages menu > Preferences Accounts like you do in iChat.
This tends to mean the Messages Menu > Preferences > Accounts looks very familiar
The Window Menu can look a little different.
CMD + 0 brings up the Messages main window (A Chat Window that does tabbed Chats and an Interface all rolled into one)
Once you have other non iMessages Accounts then CMD + 1 brings up Buddies (A combined Buddy List). It is not listed until they are logged in.
They can be unlinked in the General Section of the Preferences at the "Gather all Accounts into one List" line.
Your "desktop" can then look like iChat used to:-

IPod Touch 5g problems switching between Mavericks and Mountain Lion.

My iPod Touch 5G is set up to sync (manually) with my Mountain Lion iMac. If I connect the iPod to my MacBook Air running Mavericks, it works fine. However, if I then connect the iPod to my iMac, iTunes re-syncs all 9,000 songs - taking hours! This can't be right. Is there any way to fix this? I've tried restoring it and copying all my music back to the iPod, but it still happens. I need to connect it to both Macs, without this annoying issue. HELP!

You can only sync music and videos among different iTunes libraries/computer using the manual method of syncing. Otherwise when y switch libraries/computer, the media on the iPod will be replaced with the media in the iTunes library of the second computer.
The manual method of syncing is included here:

Using home sharing between pc and iphone

I have enable home sharing and the option does not show up on the right side of itunes. how can i get this to show and also transfer music from my pc to my iphone wirelessly. Thanks.

When you turn on Home Sharing on your PC you will only see the Sharing option in the sidebar if other computers on your network also have iTunes running with Home Sharing turned on as well.
As for how to get it to work on your iPhone go into Settings on your iPhone and scroll down to Music. Tap on the Music settings button. On the Music screen, in the Home Sharing section enter the Apple ID and password that you use on your PC.
Now go back to your Home screen. Launch the Music app. Tab on the More button on the bottom of the screen. On the More screen tap on the Shared button. You should see a list of all available shared iTunes libraries on your network. Make sure iTunes is running on on your PC with home Sharing turned on. You should now see all the music on your PC's shared library. You will not however be able to wirelessly transfer the music from the shared library to your iPhone. You will only be able to play it.

File Transfer and Screen Sharing between MBP and MBA

I am running 10.5.6 on both. MBP is connected via ethernet to router and MBA via Airport. I can access files and Share screen of MBA while working on MBP. However I cannot log onto MBP while working on MBA. I have tried every combo in System Preferences-Sharing. What am I doing wrong? I can even exchange files with an older iBook. What gives?

SandySpider,
Well, you're behind a router, but it is still not a great idea to "Allow all incoming connections." At any rate, it shouldn't be necessary.
Have you looked at the computer names for the two machines, etc., to make sure that you aren't confusing your network devices with conflicting identifiers? Put another way, your two computers are not named the same, are they?
Another thought: Some routers firewall between the wired and wireless networks. You may have to open a port on the router, or enable its "UPnP" capability, if it has one. Have you tried connecting the Macbook Pro wirelessly, and did it make any difference?
