Preview lets you color manage photos. You can assign an ICC color profile for any open JPEG or TIFF image by going under the Tools menu and choosing Assign Profile. This brings up a dialog with a pop-up menu of available color profiles. To assign a specific profile, just choose it from the pop-up menu, then click OK.
If instead you want to change the color profile to match a specific ColorSync profile, then go under the same menu, but instead choose Match to Profile. A dialog will appear where you can choose the source, and which profile you want to match.
