I just paid to have a profile made by a professional profile-making company for a printer/paper combination. Once I saved it to Boot/Library/Colorsync/Profiles , it became visible in a Finder window of the Profiles folder. (Mac OS X 10.7.5) But it is not visible from inside Photoshop CS5 when I try to use the profile. It’s also not visible to the ColorSync Utility. The person who made it is baffled. We have double-checked many possible sources of the problem, making sure we do not misunderstand one another. I have tried renaming it to end with .icc . I have tried many things, but nothing works so far. I am no expert when it comes to .icc profiles, but I have installed many of them and used many of them in Photoshop (this week, even) with no trouble at all before now. So I’m not a total newbie. But I’m baffled, too. So I come to you in the hope that you can help.
