pretty good, but not great Level 1 Level 1

My friend and I who each have a new iMac with Leopard, are trying to share screens via iChat, but it doesn't work. We both checked Screen Sharing under Sharing in System Preference's, but nothing happens. Sometimes it doesn't connect, or sometimes it says it connects for me at least (when sharing my screen), but only audio works and he says he doesn't see my screen.

Any suggestions?

HP Pavilion a1120n/iBook G3 running 10.2.8, Windows XP, PC: 200GB HD, 3.06GHz, and 512MB RAM/Mac: 40GB HD, 900MHz, and 128MB RAM

    I had the exact same problem with screen sharing. It would keep going on indefinitely while we had an audio chat. Unfortunately, I wasn't able to find a fix. Let me know!

    Whoever wrote this topic (no name displayed)
    How many times has this happened? Did you enable it in System Preferences?
    I did, but it still didn't work.
    If anyone can think of anything, let me know.

    I used to be able to move files (Iogging in via network) between my new macbook and my 2 year old intel iMac up to 10.4.10. Now I have tried screen sharing, logging in (all via the airport on my iMac I should add). None of them now work. I am not doing in iChat but still the screen sharing feature button shows up but no connection. I have screen sharing set as per apples instructions in help file but still no connection. It looks to me that this screen sharing/sharing between computers is not working right, something between Tiger (10.4.10) and Leopard is now broken perhaps. This seems to be only problem I had. Upgrade was flawless and not fret with the problems (on either machine) that a number have seen.

    Yeah, we've done the system prefs thing, but nothing changed.

    Same issues here. Trying to connect MB to PB G4 over Airport Express network. No firewall, and both enabled Screen Sharing in System Preferences. The one screen says that screen sharing is happening, but on the other machine the message about connecting just spins and spins and a connection never happens. We are able to video and audio chat, but no screen sharing.

    See here
    Says Intel only (effectively)

    Also The iChat Help on your Mac says Screen Sharing requires a @Mac account at both ends for Encryption.

    Yeah, my friend was able to do it with someone else so it works. I think my internet is too slow (about 100kbs). Thanks for all of the replies!

    Hmm. I don't read that G4's are not supported in that article (cited above). The Macbook gets the message, "you are now sharing" and the PB then gets a window that says that it's trying to connect (this never goes away). At this stage we have an audio chat, but no sharing. I've done the Qtime 1.5MBps change, and looked at sys prefs for sharing. Anything else?

    Not the above Article but the iChat helps does say that WITH the correct Core Video capable Video card a G4 Dual will be able to do it.

    As to whether you can get a Core Video card for a G4 Dual is another matter.
    The ATI update wizard suggests I can not.

    Acc. to the sys profiler, the PB G4 is "Hardware Accelerated." So I have no idea what's missing.
    Here's a representation of the screen sharing I'm attempting:

    PowerBook G4 (Google) <--- Airport Express (no firewall) ---> Macbook (Google)

    I can't figure what would allow the MB to show that Screen Sharing is on, while on the Powerbook providing a window that it is connecting though it does so only in audio, never the MB's screen.

    Sorry that should have been the iChat Help on Screen Sharing that says or a least Implies Encryption is needed.

    However just to confuse things It also says any Account type can do it.

    I have confirmed that my Powerbook G4 will not perform screen sharing. A Macbook to iMac (both Intel) were able to connect with no problems at all, but no screen sharing with the Powerbook.

    After an hour if pulling out my hair, I finally had an idea of what might be causing the crash... I noticed I had my old iSight plugged in (the external firewire iSight) into my Apple Cinema Display. I unplugged it and iChat screen sharing worked PERFECTLY. You should also know that I don't have problems with my iSight, it works well on Video Chat and Audio Chat and even presentation mode but, it screwed up screen sharing.

    In conclusion, if you're experiencing sudden connection losses with iChat screen sharing, check to see if you have an iSight plugged into your Mac and unplug it.

    This is good to hear, but I will restate that I've had no problems getting two Intel Macs to screenshare, but when the G4 attempts a screenshare with an Intel Mac, then Intel Mac says that screensharing is occurring, and the G4 just shows a "connecting now" window and then never shows the screen. What does come through is audio only---odd.
