what version of Adobe acrobat works best with Mac OSX 10.6.8?

Hi,

I have recently installed CS6 on my iMac running system 10.6.8. Illustrator, Photoshop and Adobe Acrobat Pro are the main programs I use.

Now the Acrobat Pro that came with CS6 isn't compatible with my system. (Note: I am not upgrading my system because I don't want to go on the cloud for now. I prefer to stay with CS6 and don't have access to Mavericks so I need to stay with system 10.6.8.)

Please tell me what version of Acrobat Pro works best with 10.6.8 and if there is anywhere on the internet I can buy and/or download it.

Thank you very much,

Lucinda
