Aperture 3.4.5

Serious questions posed on importing from a Canon Ti2 OSX Rebel on Mt. Lion 5.8.5 in a inconsistent results for the RAW was posed as a JEP result was coming back at times looking and responding better then the RAW imports. Getting alot of contrast changes and management of the sharpness concerns in the adjustments after loading images in the Library Project.

Response was for Digital Camera RAW Compatibility 5.01 proved to be installed. My ColorSync Utility is in correct, have reinstalled and managed some results for Library curppted photo questioned results, created new Library. Used tool to reestablish data base for the Aperture Library. Still find a result for sharpness inconsistency?
