An updated snapshot for OS X is available. You may get it here: http://dispcalgui.hoech.net/snapshot/dispcalGUI-0.5.2.9.dmgA remaining problem I'm still looking into is that the currently associated display profile seems not to be correctly reflected in the curve viewer under Mac OS X 10.6. Unfortunately I can't test it because I'm still PPC-based. I've added a bit of debug output, which will be included in the log (menu "Tools" -> "Show log window"). If you or anyone could send me its contents right after starting up dispcalGUI, I may be able to figure out (or atleast get a rough idea) how to fix it. Thanks.
