I’ve got myself an Apple Silicon Mac last year, although it’s really amazing but still have some compatibility issues. When I want to use
DisplayCAL to recalibrate my external monitor, but the it didn’t recognize both of my external monitor.
Here’s the workaround for this issue:
DisplayCAL will install
ArgyllCMS when first launch, but it won’t recognize my external monitor:
The reason why is
DisplayCAL actually not install the latest version of
ArgyllCMS (though it says it’s the latest)
So we need to install the latest version of
ArgyllCMS by ourselves and replace it (
v2.3.0 when I writing this)
Go to DisplayCAL and download the latest version of
Plug in your monitor calibrator (
SpyderXin my case)
It will prompt you to download the “latest version” of
Cancel it and download
Intel OS X 10.6 64 bit or laterfrom ArgyllCMS
.tgzarchive, and move
~/Library/Application Support/DisplayCAL/dl(version might be different)
Go back to
File > Locate ArgyllCMS executables...from menu bar.
The external monitor should appear in list after restarting
DisplayCAL, macOS might prompt you to prevent from unauthorized app to run,
remember to force open all executables from Security and Privacy settings.
I’ve ran into some glitches with this solution, it will turn the monitor black when the calibration is completed at first time, I need to re-plug the monitor cable to lit up again and allow macOS to run the last step to finish install ICC profile. It’s better to run a quick calibration at first to see if there’s any problem.
