How to Color Calibrate Your Mac Display

If you only use your Mac for browsing the Web, sending and receiving email, and working in a word processor, it's probably not all that important for it to have accurate colors. Contrarily, if you work with photos or videos, or even if you like to watch movies in the best possible conditions, calibrating your display is essential.

The calibration process tweaks a number of settings to get the colors and contrast on your Mac as accurate as possible. It does this by changing the intensity of the main colors — red, blue, and green — and setting the white point, or the neutral white color that you see when, say, you open a new document in a word processor.

It's easy to color calibrate your Mac's display. Here's how you can do it.

Color Profiles

Color profiles are settings files that tell your Mac how to adjust the color and contrast of its display. Your Mac can store lots of color profiles, and you'll find that it already has a handful. Go to System Preferences > Displays, then click the Color tab, and you'll see a list. These default profiles, with odd names, such as sRGB IEC61966-2.1, are specially designed for specific displays; you can safely ignore them.

If you select one of the profiles and press the up-arrow or down-arrow keys to scroll through them, you'll see how different your display will look. Some are very blue, others lean toward purple, and most probably don't look right.

But you'll probably find one called iMac (if you have an iMac) or Color LCD (on a laptop), which is selected. This is the profile your Mac is using. You can check Show profiles for this display only to hide all the profiles that aren't for your display.

If you see a lot of profiles in the list with names like iMac or Color LCD, it's worth checking their dates. If you've upgraded from one Mac to another, copying files from the older computer, you might find that an old profile, created for a different display, has been carried over. Select a profile and click Open Profile to see some detailed information about that profile. The Created date shows when you set it up; if it's older than your current Mac, or its display, go ahead and delete it. (You won't have the option to delete system profiles.)

How to Calibrate Your Mac

macOS includes an excellent system for calibrating your Mac's display. In the same preference pane, press the Option key and click Calibrate. The Display Calibrator Assistant opens and walks you through the process. You need to press the Option key to launch this assistant in Expert Mode, which gives you more options for detailed calibration.

When the assistant launches, you'll notice that your display's colors change a bit to the default settings. Click Continue.

Every display panel is slightly different, and your lighting is different, so the next screen helps determine the display's native lighting response. You'll find two sliders and a square in the center of the screen. Follow the instructions and move the sliders until you cannot distinguish the Apple logo from the background. Do this slowly, and take your time, because it's a subtle change. When you've finished this, click Continue.

Display Calibrator Assistant

You will see a number of screens like the ones above, each asking you to move the sliders until the Apple logo blends into the background. They all act on different colors. Click Continue after you've completed each task.

You then see a "Select a target" gamma screen. (Gamma is the contrast of the display.) You can check Use native gamma, or adjust the slider to what looks right to you. Click Continue.

Display Calibrator Select a target white point

The next screen offers to set a target white point. The only time you'd want to change this is if you have professional needs and know exactly what white point you need to use. Leave "Use native white point" checked, then click Continue.

Determine your display's native response

You are next asked if you want to allow other users to use your calibration. If you're the only user on the Mac, this doesn't matter, but if you share your computer, it's a good idea to check this so other users will benefit from your calibrated colors. Click Continue.

You can then name the profile and save it. By default, this will be something like iMac Calibrated, but you can name it with anything you like, such as a date. Click Continue.

The conclusion screen shows the details of the calibration. Take note of any information you might need, and then click Done.

Display Calibrator Conclusion

It's now worth clicking the profile you were using previously, and then clicking the new one to see the difference. One thing you may notice is that the default profile looks wrong to you; this could be due to the way you see colors and contrast or because of your lighting. What counts is that you are comfortable with the color profile. If you don't like the new profile, you can switch back, or go through the calibration process again, paying closer attention to the Apple logo against the background.

Professional Color Calibration

The above process is great for most Mac users, but if you work with photos or videos, or if you want to print your own photos and have the colors of your prints match your display, then you need a color calibrator. This is a device that hangs in front of your display and detects colors that the device's software displays. This process takes several minutes, and, at the end, the software creates a detailed color profile that is set to "an industry color reference standard." I use the Spyder5PRO, which allows me to accurately calibrate both my iMac and my MacBook, so their colors match.

If you use a device like this, you'll notice that it probably sets the colors differently from how you would do so using Apple's calibration assistant; this is because it detects the actual colors the display shows. It can also factor in ambient lighting, and some of these devices can stay plugged into your Mac to alter the color profile as the lighting around you changes. This can be useful if you have a lot of natural light, since the color temperature changes during the day, or when the weather changes.

In either case, whether you use Apple's simple solution or a hardware device, you should consider calibrating your display. You may find that the colors look better with more contrast and without a blue or purple tinge. It's easy to do, and it can make your computing more comfortable.
