My Lightroom 4.0 cannot read my RAW (CR.) files from my Canon 5D Mk1 . My MACbook can 'see ' them through Lightroom when I connect the camera but when I click import I get a message saying it cannot read the files (889)?
Can you please quote the error message exactly? Error messages that contain "cannot read" often mean that the permissions on the destination folder (where the RAW files are supposed to go to on your hard drive) are not set to WRITE permission. Please check.
Also, are you sure its a "Canon 5D Mk1"? Is that a typo? This list of supported cameras doesn't list that camera
