I downloaded these a few weeks ago and wanted to share it since I believe the threads have been removed. Don't know why. I am not the author nor am I taking any credit for these files. I just felt like posting them for anyone to have. I thought they worked out really well for me. Depending on the model screen you have on the iMac alum, it will have different effects. Hopefully they can be useful to others. If the authors are out there please post in the thread and take credit for the calibrations. Enjoy!
