Hi, which version of OS X are you using?
Under 10.7 "Lion" it seems to be necessary to run the Argyll tools that need access to the video LUTs with sudo to be able to override the current system profile (even if just clearing or loading a calibration).

Yes, it's OS X. After creating the calibration, I install it.

    Hi, dumb questions but:
       Are you setting the calibration before you do the spotread check ?
       (ie. with dispwin).
