Is there a remote desktop app that works with mac OS X?

Hi, I have a Q10 running OS10.2.1 and I would like to connect to a remote desktop on OS X Yosemite. Is there an app that can do this?

Have you tried teamviewer?

I just tried but it is only available for 10.3. I am going to bite the bullet and install a leaked 10.3 now.
