How do I enable remote control of Remote Desktop?
I am trying to control my 10.4.11 machine from Mac OS X 10.10.4. Remote Desktop is enabled, I vnc into it and see the screen, but it the options to enable control are grayed out on my window of the 10.4.11 machine. I know I could do this with iChat, but I would like the be able to do this with remote desktop like I can with 10.6 and later. Any clues as to why the mouse control is grayed out, and what to do about it?
