Step 6 : Get your color right
"By default, your new PC will have a different color profile than your Mac. At the very least you’ll have to open your color preferences and adjust the saturation until it is the same as your Mac. I recommend you pull up your 10 favorite photos and put them side by side, adjusting the saturation and color on your new PC until they are the same. Even though this system is calibrated at the factory by MSI (and has built in color profiles) this is a mistake I made and for about a week, my photos were a bit off and more de-saturated than I like. I only noticed when I looked on my wife’s mac and my photos looked less colorful than I preferred."
For someone with an established photography career this seems quite lackadaisical. Even if you aren't calibrating for screen to home printed consistency, you shouldn't be adjusting the display just for your preference. I've seen this suggested in the past "get your favorite photos up and adjust your screen until they are how you remember then in real life" or "adjust them until you like them". Adjustments to them to get them "how you like them" should be done in the editing software, not the calibration of your monitor. You should be calibrating with a tool such as i1Display Pro, Colormunki or Spyder devices, and on a regular basis. Your photos might look just how you want them on your device, but then they are going to look considerably different on other calibrated screens and devices from what you see on your screen and possibly in print.
To quote myself under my other posting name used at dpreview.com :
The major benefit in calibrating is that your photo will look the same on other calibrated monitors. Deciding you don't like the calibration and adjusting your monitor/calibration would result in the image appearing differently to other users viewing it on calibrated monitors and when you print it. Would it not be of more use to adjust the image's saturation to be as you wish it to be so that others using calibrated equipment will not see an over saturated, too red picture?
Saying calibration is an approximation to me seems counter intuitive. To me adjusting the calibration to what you consider displayed a single "familiar scene photo" to look correct would be the approximation. The calibration process is performed to give you a consistent base for working from that will result in expected results across other calibrated equipment (printers, other displays, other users calibrated displays/devices) rather than providing a "looks like the real life scene to me" preference, that is for you to achieve when editing. By adjusting the calibration to one familiar scene that was at a certain time of day, with one particular white balance, and possible reflected colours from objects within the scene, etc. etc. etc. you really aren't going to be getting a useful calibration in my mind.
