So I compiled it on my Mac Mini. $ uname -a Darwin mac.rkkda.org 9.6.0 Darwin Kernel Version 9.6.0: Mon Nov 24 17:37:00 PST 2008; root:xnu-1228.9.59~1/RELEASE_I386 i386 $ ~/Argyll_V1.0.4_Beta/bin/chartread test chartread: Error - Configuring USB port 'usb:/bus253/dev0 (X-Rite ColorMunki)' to 1 failed with -9 (usb_set_configuration(SetConfiguration): device not opened for exclusive access) No dice there, either. But I did run a printer profile using xrite's software on the Mac. There was a magenta hue to the CUPS grayscale printout after I got done!
