Reminders app waking mac from sleep

I too have this issue. I thought I was alone here. I even have it set to not display notifications for reminders, however, as soon as I get a reminder on my phone, I look over my shoulder and sure enough my iMac wakes up. Ditto on trying all of the suggested solutions. Thanks.

Hopefully Apple will fix this soon.

It's obvious that this is a bug as so many people are complaining about it!

They should fix it or if it was really meant to be a feature, at least add a toggle to switch it on/off.

Just frustration from afar here. It was definitely Yosemite and beyond. It’s been happening for so long. Also, one of those annoying things that wasn’t big enough to stop my day and write about it, about annoying enough to really bother me constantly. Argh.

All the above, completely correct and disappointing that there's not even a glimmer of a fix in the offing. How can anyone not take from this that Apple do not care about their poor software. Sad, but indisputable.

What @jd2020 says makes me sad! This is by far the most commented thread in Apples "macOS Catalina"-section and senior staff/engineers are not aware of this bug? Sorry, thats unacceptable. People are digging as deep as they can to solve this problem and Apple simply doesn't care, otherwise we would have received a bugfix with any of the last updates. Hopefully Big Sur will fix this!!!

Hello - here to throw my hat into the ring. I also had no idea why my Mac kept unlocking from my watch while I was in the other room. Thanks jd2020 for going through the support process, this is super frustrating. I hope one more person on this thread helps add some visibility to this issue.

I also worry that Big Sur will be this and more.

Thanks @hehappysymptom for the kind words. Just was in touch with Apple yesterday and I'm submitting yet another round of diagnostic files for engineering. I think they may understand this is a real problem and stop thinking I'm "doing it wrong." Well, that's what I hope anyway. I should hear something sometime next week....

Yikes, I was trying to collect some data for Apple Support and I couldn't replicate the problem today. Reminders were not waking my Mac mini on Catalina. They were about 7 days ago.

What are other seeing?

There has recently been an update to Reminders. Having thoughtlessly accepted this on my iPad, I am now unable to use Reminders (in that account) on my Mojave Mac which reports Catalina is required to utilise this new version of the iCloud Reminders data. I have not yet checked how a Catalina Mac responds to this.

However, it occurs to me that this new version may have fixed the problem. I don't yet know until I test my Catalina Mac. Is it possible jd2020 that you have allowed this update to occur? Have Apple perhaps finally fixed it?

It wouldn't be the first time that a Manufacturer, while denying a problem exists, or simply apparently doing nothing, in fact slips in a fix, at the same time insisting they've done nothing, or at least, leaving their front line support unaware of any fix.

Or does the problem still exist for others even after the Reminders update?

I'm not sure what you mean by "recently" and "new version." Reminders was updated in iOS 13, some 11 months ago. When you open Reminders in iOS 13 you're presented with the "upgrade" choice. Nothing visible has changed with the format of Reminders in Catalina or iOS 13 since September 2019. The latest update to Catalina is 10.15.6, released on 12 Aug 2020.

None of that has nothing to do with my situation, or probably anyone here. I think most everyone here talking about Reminders waking the Mac with DND set is on Catalina. The 10.5.6 update didn't change anything for me -- unless it mysteriously changed after being installed for 10+ days. Possible, but seems most unlikely. This problem doesn't occur for me at all on Mojave.

Again, can anyone else (who has experienced it) confirm whether the problem still exists?

Does 'Safe Mode' allow things like Reminders and Notifications to run? I was under the impression that all those background processes were disabled to provide a really clean and 'safe' operating environment. In which case it would be expected that the problem would not manifest itself in Safe Mode. If the problem does still exist however, then it indicates the underlying sub-systems do run in Safe Mode and the problem is with Reminders and those associated sub-systems.

Not wanting to dismiss your suggestion as any further checking is worthwhile (at least to be able to confirm that with Apple), but I am not sure it would actually tell us anything useful. Is there something else you had in mind?

No offense intended. I've not observed any change in Reminders in 13.6.1, nor is any documented. I would suggest that perhaps the update kick-started the iOS/iPadOS 13 alert to "upgrade" your reminders. Perhaps you have a list (or shared list) that wasn't upgraded previously when you installed 13.

My point was that a recent change isn't the cause of problems reported back to October 2019, and in my case, back to May 2020, which is what you seemed to suggest.

What exactly Safe Mode does isn't well documented, however it mainly stops certain software from loading at boot, in addition to cleaning up certain cache files. In practice it tends to not load 3rd party software. Apparently "Reminders/Notifications" are "required" from the reference below...

Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS.

This is a much deeper dive into Safe Mode:

This morning i verified that the Wake/Unlock problem continues for me. I have no idea why it didn't occur yesterday. I've packed up my log files and uploaded them to Apple. Hopefully this will help get some attention on this.

FYI: I have a Mac on Catalina, two on Mojave, and all other devices on the latest official OS release, except an iPhone on 14 beta 6. Your suggestion is interesting and I'm referencing it in my support documentation.

Thank you. I should have read more carefully.

Same issue on macOS Catalina 10.15.3.
