macOS Ventura: Night Shift Does the Opposite and Turns Screen Blue

Ever since upgrading to macOS Ventura, I encountered a peculiar issue with Night Shift. At the scheduled time, instead of shifting the white point towards warmer colours, it appears to do the inverse: suddenly my display turns excruciatingly blueish.

Manually turning Night Shift off and on resolves this issue until the next day. At the scheduled time it happens all over again.

I’m using my MacBook Pro in clamshell mode with an external display attached. I’m not using any other display control software. This has never been an issue for me before.

Searching the internet yields a couple of similar complaints, including a report that this already happened on Monterey (for at least one person) and a theory that it may be related to using external displays with the lid down.

What to take from this — other than another example of how Apple’s software quality is in continuing descent? It’s the details, the sweating of the small stuff that they used to more often than not get right. That extra bit of attention at the margins that delights, the tiny polishes that make an experience feel effortless and reliable. Today’s Apple appears to have lost interest in pursuing it.
