My friend and I both have Messages beta and FaceTime on our Macs and we are unable to share screens. The screen sharing option is greyed out. What are we doing wrong?

    Hi,

     

    Can your Video Chat with  each other ?

     

    Notes.

    Video chats and Audio Only chats take place over the same internet ports

    As far as Screen Sharing is concerned it is an Audio Chat +

    That is to say it is an Audio Chat with a VPN connection alongside that does the Screen Sharing bit

     

    FaceTime does not do Screen Sharing.

     

    If you can Video (or Audio Only) Chat and the Screen Sharing is still greyed out try this:-

    As it is Lion make the Finder the "front" app in the Menu bar

    Use the Go Menu

    Hold down the ALT key.

    Select the Library which can now be seen

    Open Preferences

    Find com.apple.ichat.plist  (Yes Messages still uses this) and drag it to the Trash

    Restart Messages beta.

    Hi Ralph:

     

    Thanks for your response.   A few more questions please. 

     

    - Do I have to turn on "Screen Sharing" in the Sharing System Preference? 

    - In Messages can you use your mouse to control the other screen or can you only see it? 

    - Does it work if both parties to the conversation are logged in using their mac account?  Or, do you have to log in using an AIM account? 

     

    Thanks. 

     

    Alvin

    HI,

     

    Screen Sharing in System Preferences uses ths same "engine" but does not need to be turned On for iChat (Or Messages) Screen Sharing to work.

     

    Both parties have to be on the same network.

    This could be AIM as both AIM Names and Apple IDs ending in @mac.com and @me.com login into this service. (These types of APple IDs are also valid AIM Screen Names -see notes)

     

    NOTES

    Apple IDs issued from iCloud (@me.com) can only be used in iChat 6 or Messages Beta (In Lion basically)

    Also these Apple IDs must have passwords that will work with the AIM servers (No more than 16 characters)

     

     

    Edit

    Thanks for the Points
