Has anybody else noticed, after upgrading to Mountain Lion, that an exported slice from Fireworks (CS5 in my case) is very washed out, with colors much less saturated? It is driving me crazy, I'm having to workaround by taking screenshots of my work in Fireworks which is a total waste of time. Any help is greatly appreciated.
Fireworks isn't color managed, and its output does not include ICC profiles... I wonder if the difference might relate to a change in how the new Mac OS handles images without color profiles.
Are you describing a difference that occurs when viewing the files using Preview, or a different application? (FYI: Screenshots typically have the current monitor display profile assigned to them, whereas a file exported from Fireworks would not.)
