Hello,

I have a mid-2009 Macbook Pro.

I have Yosemite installed and my computer runs like a snail. I need to downgrade my OSX, and I am wondering what is the latest version that will run smoothly on my machine? Will Mavericks run smoothly or should I go with Mountain Lion, or even Lion? I remember my computer operating fine with Mavericks, before I installed Yosemite.

Here are my specs:
