Calendar macOS Ventura crashes on entering location field contents

Fixed on Synology as of the latest Synology Calendar update 2.5.1-21153. For anyone having this issue on their Synology NAS, it looks like Synology found a way around the issue. The update mentioned that it resolved an issue caused by "some CalDav clients," which sounded promising since this works fine on older versions of Apple Calendar and on my Android calendar app.

Here is what worked for me after I realized that Calendar locations work for other accounts.

• Export all calendars to a local .ics file just in case and because this will reset all local calendars
• Disable calendar access for all remote accounts from System Settings-Internet Accounts (you do not need to delete the account, just turn the switch for calendars off)
• Quit calendar
• disconnect from Internet
• For each of the following directories (if you have them... I didn't have them all), select all of the contents, right-click and choose "New Folder with Selection"
  • ~/Library/Caches
  • ~/Library/Calendars 
  • ~/Library/Application Support/Calendars
  • ~/Library/Containers/com.apple.CalendarAgent
  • ~/Library/Containers/com.apple.iCal
• Restart your Mac
• Launch Calendar
• Try creating a new event and add a location (you will get no suggestions because wifi is off, but it should let you add text without crashing)
• Import any local calendars, by importing the .ics file you created. Do not import exported calendars that were stored on a server or you may get duplicates later.
• Turn on internet access
• Enable calendar access for remote accounts and allow them to sync
• Test creating a new event with location info.

Today I installed Synology Calendar Beta 2.5.0-21111 and entering location works as intended - no crash. Let's hope it fixes this annoying bug.

watch:

Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac?

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

The problem has been fixed in DAViCal, but you will need to check out the latest Gitlab repository to get it work. The official version 1.1.12 still has this problem, but a new version will be released soon.

It was fixed by adding the ROOM principal type to avoid that bug.

Hi, this issue has been fixed in the Synology Calendar 2.5 Beta.

I have a Workaround as long as Apple will hopefully fix this issue.

1. Create the Calendar entry in your iCloud Calendar with entering the location
2. After saving the Calendar entry, move it to the Synology Calendar

Et voilà: Calendar Entry has a location and is being stored on the Synology NAS.

The miracle finally happened: macOS Ventura 13.4.1 has apparently fixed the calendar location bug. I'm about to cry...

First thing to try is "Restart" Calendar while continuously depressing the "shift" key.

Next, if that doesn't help restart your computer using Safe Mode, and test again.

Everyone needs to report this to Apple support. They will ask you to try a few things which is a pain in the _ _ _. For example, this includes checking to see if it's a problem with another Synology account to rule an account issue out as a problem. Once you try their few "ideas", they will have a higher level support person call you. All should do this. It's probably the only way this gets fixed. Who has done it?

The same problem. Also with Ventura 13.2. Apple Calendar is paired with CalDav on Synology.
The third-party app Fantastical works fine.

This was reported in 2022 after the regression was introduced with macOS 13 Ventura. The issue currently has status "open". Synology is aware as well and claims to have reached out to Apple.

Last week tried a few times to escalate this via telephone. Success depends a lot on support staff, so your mileage may vary.

The longer I use Apple products the less I become hopeful, they can manage to resolve issues around essential functionality. I also become less interested in macOS overall to be honest.

The last resort to prevent engineering from actually looking into this is, Apple asking to create a fresh install on a new volume. If anybody has the resources, please create a new volume with macOS Ventura without iCloud and no other calendar accounts except the one resulting in the crash.

Then send sys diagnose and crash log to mothership and hope, that finally engineering is willing to actually look into this problem.

Happens to me too since the Update to Ventura. But only for my Caldav calenders, not for iCloud and Outlook.

The Caldav backend is Davical.

Syncing location from the backend is fine, the Apple calendar only crashes, if I enter a new location in the frontend.

After 3 days, the problem returned on my Macbook when entering an event location. I've since tried using a demo of BusyCal which looks like a good calendar app. It does not crash when entering locations and successfully syncs back to Synology calendar, however it does randomly crash while running in the background. Console shows that it crashed without presenting a dialog 4x today. It seems as though Apple has broken iCal sync which is impacting all calendar apps.

Which version of Synology DSM is everyone using. I'm on 6.2.4 Update 7 and am wondering if an update to 7.2 would offer any relief.
