I'm not the only one which has noted this behavior on Snow Leopard. Do you have tried the program on the last mac OS? When I feel in my password it did not catch it. Thank you for this project that bring near many user to a great software, but I stay waiting for the implementation of the profile verification :-) Ciao Marco ---- Messaggio originale---- Da: lists+argyllcms@xxxxxxxxx Data: 05/11/2009 20.02 A: <argyllcms@xxxxxxxxxxxxx> Ogg: [argyllcms] Re: R: Re: Difficult in calibration 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).
