Apparently in Lion, the user library where these profiles may have been installed is invisible by default and needs Admin privileges to access. If you hold down the option key then the Go menu has a Library choice to open it up.
Do you mean you are visually unable to show the profile in Finder to verify it is correctly installed, or the profile is not available in the printing profiles drop menu, or both?
If you found the answer, please post it...
The ICC profiles are not visible to Applications as Output profiles i.e. Printer profiles. We have double checked the paths and they are correct and the profiles are installed. but they do not show up in Indesign, illustrator etc as a printer profile... In fact no cmyk profiles (even those supplied from Adobe i.e fogra39.icc) show up. When we open up colorsync we can see them but when we try any application to output to a cmyk print (laser or inkjet) the cmyk profiles are not visible.
any help much appreciated in advance
Did you run the profile first aid in the utlity?
