BEFORE i upgraded to Mountain Lion, iChat video worked fine.

NOW video chat does not work with Messages (see attached screen capture).

 

the camera is detected and working (green led comes on when i open Audio/Video Preferences), but Messages thinks the machine does not support video chats.

 

any ideas?

    Same issue here. But it does work if I log in to a different users account on my computer. I am guessing it is a messed up preference file somewhere. Just not sure which file it would be. Would really like some help with this.

    Thanks

    The Messages app replaces iChat in Mountain Lion. Ralph explains things well in THIS THREAD.

    I understand that Messages has replaced iChat. We are trying to figure why video chat is not working. It is still an option and is working on a different user account on my MacBook Pro but not working under my account login.

    My mistake. Techcafe mentioned iChat and I thought you were trying to run iChat on ML.

     

    Have either of you tried resetting SMS? If no, try and see if it has any effect. Instructions HERE.

    I just got it working. All I did was switch to a different wireless network. It started working so I then switched back to my network and it kept working. Not sure what the bug is but all is well now. Give it a try and see if that fixes it.

    No clue as to what is wrong, but others have suggested to start up a terminal window and enter "defaults write com.apple.iChat newbwdup 300000" and then restart Messages/iChat.

     

    I have had this problems on several computers after upgrading to ML, and the solution works.

     

    It may also be possible to delete the ichat and messages preference files in your Library/Preferences directory. To get to the library directory, click on the Go menu in Finder, and then press alt/option and Library will appear as a menu option.

    Hi,

     

    This is to do with what Internet speed Messages or iChat thinks you have.

     

    At application start up there is a check on what Internet Speed, both up and down there is.

    If the App Starts up when the computer does the process of establishing a network can distort the figures.

     

    mholm80's post is an old way to fix it.

    Writing direct to the com.apple.ichat.plist saves having to delete it and then reset all the preferences and some menu choices

     

    You could delete the plist.

    You can check the computer is not busy doing other things

    You can check other computers are not using the same network with downloads and the like.

     

    Also try changing the Bandwidth in the pic to 500kbps and restarting the app.
