Accessing “Expert Mode” Screen Color Calibrator in Mac OS X (Mojave, Sierra & El Capitan)
Mac users are likely familiar with the process of using display calibration to get the best color and picture quality for a specific monitor or screen used with a computer, and to get the most out of the calibrator tool you’ll want to run the utility in Expert Mode. While Expert Mode used to be immediately visible in the Display Calibrator Assistant, it’s now hidden by default in the newest versions of macOS and OS X. This has led some Mac users to think the Expert Mode advanced color calibration options are missing in Mac OS X now, but in fact it just requires an additional step to access.
From OS X El Capitan (10.11) onward, including macOS Sierra 10.12, High Sierra, and MacOS Mojave (10.14.x), to access the Expert Mode of Display Calibrator, including support for adjusting Native Gamma and Target Gamma, you’ll need to use a simple trick to reveal the additional options.
How to Calibrate Screen Color in Mac OS
- Open System Preferences if you haven’t don’t so already and go to the “Display” preference panel, then go to the “Color” tab as usual
- Hold down the OPTION key and click on “Calibrate” to access the Expert Mode options in Display Calibrator
- Proceed through the screen color calibration process as usual in Mac OS X
You must hold the OPTION key when clicking Calibrate to access the Expert Mode advanced color calibration tools, without holding down Option the expert option will not appear.
If you haven’t done so yet, adjusting screen calibration can be a helpful way to improve the appearance of any display a Mac connects to. I always calibrate my displays, even the built-in display panel on a MacBook Pro, since I find the default gamma to often be too bright, whereas some users may find it not bright enough. It can also offer a great way to correct a display that is either too cool or warm looking.
