This is becoming a growing issue for us, to the point where I'm actively looking for alternative solutions.  Remote control works great for Windows computers.  But for Mac OS...not at all really.  Maybe 1 out of 10 times will I actually be able to connect to the Mac.  And even then, oftentimes my mouse wont actually be on the remote screen where it shows up on my side.  I just don't know what else to try.

We are experiencing similar issues. Seems to be hit or miss, mostly miss. Cant figure out any trends, doesn't seem to matter what OSX version.
