Mac OS X Version 10.6.8 build 10K549

Question

Hi,
My first question is how do you tell the flavor of mac os from the build e.g.snow leopard, lion, maverick etc ? The kernel build in system profiler says Darwin, is that what determines the flavor ?
My actual problem is apple tv icon is not showing on the task bar. However, apple tv is working fine with iTunes ?
I have mid 2009 Mac Book Pro Mac OS X Version 10.6.8 build 10K549 fully updated as reported by OS update utility in the 'About Mac' option. Any suggestions ?
BR,
Sarfraz.

Check that your computer is compatible with Mountain Lion/Mavericks.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
iMac (Mid 2007 or newer) model number 7,1 or higher
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
MacBook Air (Late 2008 or newer) model number 2,1 or higher
Mac mini (Early 2009 or newer) model number 3,1 or higher
Mac Pro (Early 2008 or newer) model number 3,1 or higher
Xserve (Early 2009) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.
