“In Mac OS copy your third party profile(s) to „/Library/ColorSync/Profiles“ or into „/User/[Username]/Library/ColorSync/Profiles“.”
In case your Profiles directory is locked, take a look at it in FINDER while clicking “Cmd i” to bring up the Informationbox of the directory and click open the little lock-symbol at the bottom right. OSX is likely to ask for your Admin-Password in order to free the access to unlock the lock. Select “Read & Write” if not already set.
After copying your ICC-Profile(s) in “/Library/ColorSync/Profiles” just restart your application.
