One of the annoying features of every update that Apple provide to there operating system is the removal or hiding useful advance options were in the previous versions of the operating system. In this case Apple have hidden the advance calibration options, very useful if you want to calibrate your screen colours. The options is in the normal location, but give no clue that it is there.
Calibration of your screen is normally located within System Preferences > Displays > Color > Calibrate. If you press the button you will be given a calibration that looks like the image below. This is the cut down, reduced version of the calibration options that are normally present in previous versions of the OS.
To get to the advance calibration, simply hold the alt key as your press calibration from the system preferences. You will then be given more advance options for use.
Normally when you press the alt key, the button you are clicking or the menu item will change description, giving you a hint. This isn’t the case.
