Okay, so I checked most applications that use the iSight. I tried using Photobooth, Facetime, Skype, and they all worked fine.

However, when I turn on iMessages, the green camera signs don't pop up next to my friends and myself.

Also, when I checked up the Prefrerences -> Audio/Video , the green light beside the iSight pops on but tells me that

"this computer does not support video chat."

It worked fine until yesterday, and I haven't dropped my mac or anything like that. Can anyone please help me out?

    HI,

     

    It depends which Account types you have in the Messages App.

    The App should still show you the Preview pic in Messages > Preferences > Video  even if you only have the iMessages account active.

     

    If not try Enabling the Bonjour one.

    The Bonjour, AIM (and valid alternatives) and Jabber (and it's alternatives) will do Video in Messages (Like iChat)

     

    The iMessages account will invoke FaceTime

    Any Yahoo account is then Text Only.

    Hi,

     

    So the Buddy Lists don't show the Green Video or Audio icons for your Buddies.

    Is there a green icon next to your Buddy pick to indicate you can Video Chat ?

     

    In the Video Menu is Video and Audio ticked ?

    In the View Menu are the Show Video and  Show Audio Status items ticked ?

     

    These are the default things that can be set that might effect this.

     

    After that it might be the actual Internet speed the app thinks it sees

    Check a Speed Test

     

    It could be the setting in Messages > Preferences > Video > Bandwidth Limit drop down is set too low.

    (this would not explain why it works at School but I am trying to eliminate possibles)

    Umm,

     

    iChat or Messages will "read" the Internet Speed it can see when it starts up.

    If this is at the same time as the computer the speed seen can be Off by some margin.

     

    The fact that it thinks there is not enough to do Video does seem a bit strange though (absence of Video icons and being unable to turn it back On again in the Video Menu).

     

    Once the app has "read" the speed it writes it to the .plist involved.

    If you navigate to ~/Library/Preferences and find and highlight com.apple.ichat.plist

    You can then chose to view it with Quick Look.

    You should have a section near the bottom of the text that looks a little like this

    As iChat is sharing the internet with other apps and possible other computer it registers the "Bandwidth" the portion it can use.

     

    Bwd (bandwidth) down is  above 30Mbps for me.

    Upload (bwdup) is well over 9Mbps.

     


    Alternatively you can start the App from Terminal.

    Have the app shut down and then Launch Terminal.

    In Terminal then Paste the following:-

     

    /Applications/Messages.app/Contents/MacOS/Messages -errorLogLevel 7

     

    This will launch the app and create a Log in the Terminal app.

    It will pause once the Buddy lists are logged in.

    It will look like this at the bottom of the Log at this point

     

    External IP: XX.12.XX

    .145

    External Ports: 16403, 16403, 16403

    CNAT_BADTEST ....... 0

    CNAT_ISFULLCONE .... 0

    CNAT_ISPAT ......... 0

    CNAT_ISPATHOST ..... 0

    CNAT_TRYPRESERVE ... 1

    CNAT_PATINORDER .... 0

    CNAT_BLOCKIP ....... 1

    CNAT_BLOCKPORT ..... 1

    CNAT_LOOPBACK ...... 0

     

    You can quit the Messages app in the normal way and then study the Log.

     

    It will have a couple of lines (most likely repeated) that read:

     

    195722.863397 BWD: GotBandwidth: 9168088/34751348 (up/down) @[11.0.168.192:0.255.255.255]

    195722.863411 BWD bandwidth: 9168 kbits up, 34751 kbits down.

    The total number of bytes, the LAN IP (backwards) used and the speed in kbps.

     

    If the bandwidth you see is nowhere near your Speed test then delete the com.apple.ichat.plist and relaunch the app.
