Hi,

regarding the profile installation error in dispcalGUI, it's probably just a permissions issue - normally it should prompt for a password when you select system scope upon profile installation, if it doesn't work (maybe no password set?), try user scope instead. (The AppleScript related errors are also interesting, as I don't use the mentioned script anywhere in my code, but atleast you can safely ignore those).

Regards,

Florian Höch

Yes, now maybe I understand, the reason is the luminance which was too low even if Dispcal said 120 cd/m2. Dispcal luminance reading are not in agreement with Xrite software: the same luminance are read by dispcal as higher. Why?

Below the DispcalGUI report with its final error when has to store the profile in the right folder.

Thank you

Marco

Hmm. Setting -v2 doesn't change the code behavior, it just
reports more information on what's going on. So any improvement
is due to some other reason. One possibility is that the display may have been behaving more repeatedly at the time of this run.

If you are compiling from source, you could try lowering the REFINE_GAIN factor defined in dispcal (ie. try 0.5), and see if this has any effect on your situation. Given that your runs seem to be varying a bit, this could be
difficult to judge.
