Edit repeating events in Calendar.app in Golden Gate

This does not appear to be an issue with macOS 27.0.1 Golden Gate, but rather something specific to your Mac. To change a repeating calendar event, follow Apple's instructions:

Set up all-day, multiday, or repeating events in Calendar on Mac - Apple Support

How to Change the Time for All Future Events

• Open the Event Details: Double-click (or force-click) any occurrence of the repeating event in your calendar.
• Access the Time Field: Click directly on the event's start or end time inside the details window.
• Modify the Time: Adjust the time or date fields to your desired new schedule.
• Save and Apply: Click OK or close the event window. A confirmation dialog will appear asking if you want to apply the change to All Future Events (or similar series options) rather than just the single instance

I cannot replicate the situation that you describe, nor can I contrive to see the first popup screenshot you show. When I change the time of a repeating event in an iCloud calendar, I see the expected popup.

If does not matter which event in the series that I edit, nor does it matter if the series started in the past or the future (relative to today).

Your first screenshot references a date change, not a time change. When I change the date of a repeating daily event, I get a similar popup with the just the event or all future events, the only difference is that popup appears in the center of the screen and can be dragged (which I did), compared the screenshot above where the popup is centered on the Calendar app itself and not moveable.

I see the equivalent popup when I delete a repeating event.

Since what you report is not normal behavior and I cannot replicate it, that suggests a specific issue with your iCloud syncing. The first step is to toggle calendar syncing. Go to System Settings > iCloud, in the Saved to iCloud section click on See All (upper right) then toggle iCloud Calendar off then back on.

If that does not work, try signing out of then back into your Apple Account.

You’re right to question this.

Calendar has traditionally allowed you to edit a repeating event and apply the change to that occurrence and all future occurrences. It’s understandable, therefore, that you would expect the same option in macOS 27 Golden Gate.

The key distinction is between changing a single occurrence and editing the recurring series.

What to try in macOS 27 Golden Gate

1. Double-click the recurring event in Calendar.
2. Open the event details and select the date or time.
3. Check the Repeat settings to confirm that the event is still part of the expected recurring series.
4. Try changing the time and saving the event.
5. If possible, test whether the same behaviour occurs with another recurring event or in a different calendar account.

If the dialog still offers only Just This Event and Cancel, select Cancel to avoid unintentionally changing only one occurrence.

I haven’t been able to confirm whether the missing All Future Events option is an intentional change in macOS 27 Golden Gate or a software issue.

Apple’s Calendar documentation covers working with recurring events, but it does not establish why this particular option might be missing in your situation.

For reference, see the Apple Calendar User Guide for macOS.

One question that may help narrow down the cause: Is the event stored in an iCloud, Google Calendar, Microsoft Exchange/Outlook, or On My Mac calendar?

The calendar account may help identify whether the behaviour is related to the account, the recurring event, or the software itself.

If you believe this feature is not working as expected

I recommend submitting feedback through Apple’s macOS Product Feedback page. Describe the missing All Future Events option, the steps that reproduce the issue, and the calendar account you’re using.

This will help Apple understand the problem and assess whether a change or fix is needed.

Ok, done some more testing.

This all relates to iCloud calendars (I tried several).

If I try to change the time (just by 1 min.) of e.g. the next event, I get this:-

However, if I try to change the time of the last event, this is displayed:-

So it seems as if this aberrant behaviour is for events that have not yet taken place. Those that are in the past allow you to choose. This makes no sense.

Anyone think this is not another Golden Gate bug?

The change I was making was to increment the TIME by 1 minute. I thought I had stated that. It was just a way of testing after I tried to make a more significant change that was required. I also tried with several different repeating events and the observed behaviour was the same in every case.

Yes, that was clear and that was what I did in my test (changing an event scheduled for 1:30a to start at 1:31a).

It is certainly puzzling if you're not seeing this, but I am and this sort of inconsistency is I'm afraid purely down to Apple.

That certainly could be. I checked on another Mac in the house running Golden Gate and it behaves like mine, i.e., the expected behavior of offering the option to change just one event or all future events.

If restarting the Mac and/or signing out of iCloud and back in changes the behaviour in any way, then again, it's an Apple error. Let's not pretend otherwise.

As always on these forums, troubleshooting is the user's choice. For some reason, many people who take the time to post an issue here would prefer to attribute the problem to Apple and hope for a fix, rather than perform suggested troubleshooting steps. Personally, I believe that hope is not a plan. In this case, it's your issue to either live with or try to address yourself. Good luck!

Taking into account that Golden Gate has only reached a point 0.1 version which in and of itself was a Security Update

I might hold off deeming this as a Bug and more of something that may or may not be addressed in subsequent a True UpDate

iCloud Calendar is most certainly on as everything is shared and sync'd across all my devices (several Macs, iPads and iPhones). Although not really sure why iCloud syncing should have any impact on the observed behaviour.

The change I was making was to increment the TIME by 1 minute. I thought I had stated that. It was just a way of testing after I tried to make a more significant change that was required. I also tried with several different repeating events and the observed behaviour was the same in every case.

This Mac is an M4 Studio that I set up from scratch and did not migrate anything. Just manually copied what I needed so it was as 'clean' as possible.

It is certainly puzzling if you're not seeing this, but I am and this sort of inconsistency is I'm afraid purely down to Apple. Their 'latest and greatest' OS should never behave like this. Why does that dialog even exist within the app's code. Under what circumstances would a change to a repeating event not allow the user to apply that change to all future events. In any case, Apple have decided that is something they must incorporate into the app, but under some circumstances no doubt impossible to fathom, they are applying it incorrectly.

Or, there is some obscure setting that can cause this behaviour, but if that is not the case (and it appears not), then it's an Apple error.

If restarting the Mac and/or signing out of iCloud and back in changes the behaviour in any way, then again, it's an Apple error. Let's not pretend otherwise.

I just checked on my MBP running Golden Gate. I also saw what you saw: the expected behavior of offering the option to change just one event or all future events. When I deleted the text event, I was given the option of deleing just the one event or deleting all of them.
