iChat screen sharing and video not working on MacBook but works on Mac pro
I have a MacBook and MacBook pro. Both have the lion os 10.7.2. I can use iChat on the MacBook pro for screen sharing, video chat, and text chatting, with others remote to me. However, I can only do texting with the MacBook. I can do screen sharing via Finder between my MacBook and MacBook pro. I can do FaceTime between both systems. I can also do FaceTime between the MacBook and anyone remotely.
I also tried installing teamviewer on the MacBook, and on a remote MacBook..... And I get the same results where I cannot share the screen, from the one that has not been working.
I have checked the settings under system preference and made sure screen sharing was enabled. I have checked under iChat under video to make sure screen sharing was checked.
The macbook that is having this problem is configured for AIM for iChat
I have run out of ideas. Any suggestions on what I might try?
Thanks
MacBook, Mac OS X (10.7.2)
