I updated my camera to a Canon 70 D and can't get my RAW files to upload into my Lightroom 4. I am on a 2013 Mac Book Pro, Yosemite OS X
You need a minimum of Lightroom v5.2 to import directly into Lightroom.
You can use the Adobe DNG Converter to convert CR2 to DNG first and import that way if you don't wish to upgrade your version of Lightroom to the latest.
