If you use one of the below listed ColorEdge monitors, you may choose to calibrate your EIZO on another computer, then plug it back in to your Mac.
Older ColorEdge models can only be calibrated with ColorNavigator 6 (list below).
ColorNavigator 6 does not work with Mac OS Catalina 10.15 - it is 64-bit compatible only.
CG220, CG221, CG222W, CG223W
CG241W, CG242W, CG243W
If you use one of the above listed ColorEdge monitors, you may like to use another computer (OS must be compatible with ColorNavigator 6) to calibrate your EIZO, then plug the calibrated monitor back into your Catalina Mac. If you decide to take this option, please make sure of the following:
You should be armed with your calibration settings, a USB stick, relevant cables (read (b) below), and both computers.
When you connect your monitor to the computer you will use for the calibration: The SAME SIGNAL INPUT PORT on the monitor side must be used. Eg, if you are plugging into the Monitor's DisplayPort socket with your Catalina Mac, you must do same with whichever computer you will be running the calibration on. It doesn't matter from the computer end, it does matter at the monitor end. The calibration is always partitioned to that signal input section of the monitor's logic chip.
During a monitor calibration, an ICC profile (called a monitor profile) is created automatically in the background, and saved to your system folder. This profile describes the monitor's colour and brightness personality. Software such as Adobe Photoshop will refer to this profile to understand more about how you have set up your monitor, and how it is translating and displaying the RGB colour numbers. This all happens at OS level - no human intervention required. Because of this.... When you have finished calibrating your ColorEdge on "other computer", you must make a copy of the monitor ICC Profile & copy it into your Catalina Mac's ColorSync folder, then select it to activate it.
Here's where the monitor ICC profile will be found in a WIN PC: C:\Windows\System32\spool\drivers\color
Here's where the monitor ICC profile will be found in a MAC: Library/Colorsync/Profiles (at admin level), or Users/<username>/Library/ColorSync/Profiles
(Search .icc or .icm if you can't find the folder)
After copying the monitor profile over to your Catalina Mac, you must activate the profile. Open your Display Preferences, select Color, then select the profile. If you have more than one monitor connected to your Catalina Mac, make sure you select the right one for the EIZO (the monitor profile name usually includes the monitor's serial number).
For ColorNavigator 6 - we recommend you download Dr Les Walkling's video guides. Click on button or screen snip below.
The Basic Monitor Calibration Video should be enough for most people. You may use the same settings that you used for your CN6 calibrations, or you may prefer to use Dr Les' settings.
