Now............ Screenshot connecting from my iMac to my MacBook. http://www.grabup.com/uploads/8e6a461178b52a881cb764a1112a30b8.png?direct Screenshot connecting from my MacBook to my iMac. http://www.grabup.com/uploads/2e80cdd8cfc9725ecce09a2fa3d6e5e5.png?direct Not happening. I am hitting the "share screen" button in finder attempting to do the same between the iMac and MacBook that I am doing from the iPhone. I am failing at using finder to do this, however through a third party VNC client I can do fine. I WANT to use the built in capabilities of the OS. Both computers are on 10.5.6. As you can see the passwords are set up and work for the iPhone using third party VNC software. What am I missing here?
