Accessing Premiere Pro CS6 to Run on Apple Mac OS X in the Modern Day?

Hello Adobe Family!

I just got assigned into a new role at my work, which was given me the opportunity to develop videos for them. They want to attempt to house me on a system that gives me access to all the tools I need to edit right from work. The system they had available for me at this time is a Mac OS X Ver 10.7.5, and they wanted me to see if I could use this device to access a version of iMovie or Premiere Pro that would work for their current projects.

Unfortunately, 2012's iMovie doesn't even have Tracks and Layering, only transitions and splicing (SO. WEIRD). Regardless, I have been on the research hunt to see if there is an Adobe Premiere Pro out there that would be able to work on a Mac Computer of this operating system, as attempting to download the current version instantly boots me back to the main page of the Creative Cloud... Any suggestions?

Thank you!
