Im using CS4 Photoshop and bridge on Mac 10.8.5 and unable to open Canon RAW files from new 5D Mk 111, when I follow the links on this forum it says I need 6.5 or 7.1, but when I check before downloading it says will not be compatable with CS older than CS5, any ideas what I can do please? I am unable to upgrade the CS due to conflicting with other programmes.
