I was using iChat tonight and was sharing my screen with my father. The option to share his screen is greyed out. Is there anyway to "enable" his computer? It is a MacBook Pro (Intel) with Leopard installed. I appreciate the help.

I think he has to invite you or you have to request it. Those choices should be part of an iChat menu.

They are, but they're greyed out.

Are you both running Leopard? Fast enough connection?

I'm not sure about this, but do you need to enable Screen Sharing in the Sharing Preference Pane for it to work in iChat?

I believe so yes. In fact, you can invite someone who does not have it turned on and the invitation just times out as if there was an ordinary netowork error instead of correctly informing that one user has not enabled the feature.

Screen sharing is enabled on both computers in Sys Prefs. They are both set up the exact same way. I can share (he can control my puter) but he can not.

What happens? Time out?

Is he behind a router?

MacOS-Fan · Oct 31, 2007, 08:03 PM

Just a cable modem, to a hub, to his iMac.

Cable modem may well not have the ports open to allow video chat.

Cold Warrior · Oct 31, 2007, 09:22 PM

a cable modem shouldn't have any ports closed. It's just a modem. The "hub" (you mean a router?) might. If it's Comcast, maybe they're killing the connection with their Sandvine traffic shaping bullcrap -- if they're confusing it with file sharing activity.

Define "hub". Does this hub have a configuration menu?

C.A.T.S. CEO · Nov 1, 2007, 09:14 PM

Do you have UPnP enabled on both your routers/modem/hub?

I'm having the exact same problem, which is really annoying because I need to see my moms screen in to build a website with her.
Her config: eMac 1.25GHz, leopard, over airport extreme wireless, conected to cable modem.
My config: Macbook Core2Duo 20. GHz, leopard, over Telus wireless router, dsl connection

sharing on both are activated in iChat and system prefs

She can connect to mine, but i can't connect to hers

By "hub" I mean a dumb box so to speak. It is just a 4-port hub with no config options.

Video chats work fine.

Our modem (ADSL though) is also our NAT and DHCP server. I would have thought it would break screen sharing unless I mapped those ports through to my machine. I'm not sure about his cable modem though.
