Profiling with DisplayCal breaks the current macOS built in NightShift feature.

Once profiled, a machine will not longer shift the colors to a more ‘yellow/orange/less blue’ look – even when the macOS built in scheduled enablement of that feature is turned on – or when directly manually enabled.

I started a forum post and others have noticed the same – where NightShift is only functional after a system re-install – which points to an issue that is not user specific, but rather affects all users on the system, regardless of their selected monitor profile.

This would seem to indicate that something in the way that DisplayCal interacts with the host system disables NightShift. A preference file? Unsure.

  1. I have fixed the issue by re-formatting the MacOS of my MacBook Pro and NOT restoring it back from Time Machine.

    After re-installing MacOS, use Migration Wizard to transfer the user home folder back from the Time Machine but not other things (e.g., exclude System Preferences and Applications)
