I hated to return my new iMac but I could never get the calibration on for editing pictures. The brightness was just way to high on the new monitor. I was having to hyper lighten then to come even to get close to what I was seeing on print. Very sad day since I enjoyed using this computer. I talked with several prof camera stores and each said the new Imac glossy screen was not recmomended with photo editing. Oh well maybe some fix will come around and I can get another in the future. It was more important for my prints to match though.
