When a display is calibrated by a user, a ColorSync profile is saved in that user's home folder. Instead of calibrating the display for each
account, you can copy the profile to other accounts' home directories by following these steps:
1. Log in with an administrator account.
2. Choose Apple Menu > System Preferences.
3. Choose View > Displays.
4. Calibrate the display.
5. Once calibrated, the ColorSync profile is saved in this folder: ~/Library/ColorSync/Profiles/
Note: The default name is "Calibrated Profile.icc".
6. Drag the profile to: /Library/ColorSync/Profiles/. Note: You may need to make some of these folders if they do not exist.
7. Log in using a different account.
8. Choose Apple Menu > System Preferences.
9. Choose View > Displays.
10. Click the Color tab, then select the correct profile.
11. Repeat steps 7 through 10 for each additional account.
