Screen sharing has been a real savior with dealing with my parents and now I wanted to be able to help my daughter with her new MBP...

So she has Mountain Lion and I have Lion she is running messages and I still have iChat and it was a no go!

So I download the beta of messages and its still a no go...they are there but greyed out.

From reading the Apple forums, I have went to syst prefs and under iCloud selected back to my mac and under sharing checked screen sharing....still a no go!!

Can anyone advise?

TIA Joe

Get TeamViewer, it's free for non-commercial use. You both install it, launch it, she gives you her ID and password. It's pretty easy to use.

All depending on the hardware combo I have found the recent version to have some quirks sometimes with double-clicks, but that's always accomplished by Command-O. You can set it to start at system startup if you need to do restarts and want access right after the restart. It always gives the same ID number when it starts but generates a new password. You can also lock in a secondary password for unattended access.

It gets through any router/modem, no need to mess with port forwarding or anything.

Agreed on that.. TeamViewer is what we use at my work.
I know of a couple of IT guys that use it and like it.

THANK YOU !!! I will for sure check this out.

But out of curiosity.....will Messages have this working like iChat?

Jim and I use it once in a while so he can look at my pet porno collection!

I've done some research, Screen Sharing seems to be hit or miss in Messages. I've seen setting the router UPnP, port forwarding, Buddy lists, and other hoops mentioned. Too much, it shouldn't be that hard. Something is broken at the moment and it seems it's been going on since the beginning of the year with no solid fix yet.

Try Team Viewer, no hoops. When you go to teamviewer.com they have a big button to install now, you can talk her through that, then the rest is a breeze. Install yours first then you can talk her through it. When you reach the screen for unattended access don't choose that, it sets TV to start with system start up, if you need that you can do it later in TV preferences.

Team Viewer works great!! Thanks so much. Now since I've killed iChat on my machine and have everything working with my duaghter, I gotta get my parents set up on Team Viewer.

THANKS!!!!

Glad it worked out for you. I use it to connect to Windows machines, and a wide range of OS X from 10.4 to 10.8. I don't know why Apple with all of its money can't make something just as compatible. They do know what's best for us I guess. LOL.
