I just upgraded my old macbook to a macbook pro, I haven't been able to run the newer version of photoshop on my old macbook but I am noticing in photoshopCC 2014 the color picker on the mac is in the older format. When I run this in a windows 7 desktop I have an updated color picker interface. Is this simply a platform difference or is there some preference for the newer interface? Not the end of the world for me but for windows to be showing an update that the mac does not seems odd to me.
You mean the color panel?
If you look in the fly-out menu for the color panel in photoshop cc 2014, there should be the choices for several different color panel interfaces.
Your sure on your mac pro that you have photoshop cc 2014.
Look in photoshop under Help>System Info and at the top of the list is the photoshop version.
Posting screenshots might be useful to clarify what you are talking about.
