Wakes (CalendarDate), although related UI settings are off

Hi everyone,

I need help stopping the maintenance wakes due to "CalendarDate".

All apparently related UI settings are off (Calendar: manual refresh, no notifications, time to travel OFF, Settings > Time & Date > Automatic time & date OFF)

Two days ago, I got hourly dark wakes, but then I turned "Automatic time & date" off, and now I only got 5 wakes instead of 10, but I think this still shouldn't happen with all these settings off.

I would appreciate any help.

System:

macOS 26.1

MacBook Pro 2019

Are you build a product for macOS where this is relevant? If so, can you explain more about the background to that. If not, I suspect that the Apple Developer Forums aren’t the right place for you, and I encourage you to pop on over to Apple Support Community, run by Apple Support.

Hi Quinn!

Many thanks for your reply and sorry for the double thread. I hadn't realized that the first one was waiting for approval, so it wasn't showing up in my activity list.

Anyway, I came here from Apple Support Community, where I had a pretty bad experience regarding inappropriate behavior of senior members on a similar, but already resolved issue (TravelEngine and OSAnalytics setting wake alarms, while relevant UI settings were off).

Long story, but basically I got a "last warning" there because I kept addressing the fact that instead of receiving answers to my actual question, senior members were gaslighting me, insinuating that I had somehow altered system files and even straight out lied about what was written and then edited/removed posts in order to try and support the lies. I already reported the behavior to Apple, but I'd rather not post anything there anymore.

To answer your question: no, I'm not building any product, I am simply trying to find a way to stop automatic dark wakes, if that's possible.

This might actually be a bug, and I already submitted a report through Feedback Assistant (FB20986542).

If this is not the right platform to get technical support for this, then feel free to close the thread.

Thank you and have a nice day/evening.

no, I'm not building any product

OK. That puts this outside of our scope here on DevForums. But I’ll leave your thread here, just in case someone else wants to chime in.

Ok, got it. Many thanks for your time!
