Since installing Sequoia OS yesterday my computer is freezing and I cannot use calendar app - any suggestions on how to fix or uninstall and revert back to my old OS?

MacBook Pro 16″, macOS 15.0
I posted a week or two ago with the same issue. A few days later i gave in and chatted with apple support, which escalated 3 times until a senior tech called me to work through the issue. Long story short, everything she offered and tried did not work and she was surprised and said she had not seen this before (even though I told her many people in the discussion group were posting with a similar experience). The next day, though, I figured out a fix myself.
Problem: If I launched Mac Calendar on Sequoia 15.2, wheel starts spinning immediately, then about a minute later error message that my mac is running out of application memory. From the list of applications, the calendar is taking 150GB and the number keeps climbing. Only option is to force quit the Calendar.
TLDR -- Solution that did work was:
1) Launch Mac email
2) Click Mail/Accounts. For each account that has calendar activated, disable the Calendar. Even if it says it will delete that calendar from your Mac.
3) Once you're done disabling all calendars accounts, launch Calendar App. That's the first time in a couple weeks it did not require a force quit, because it's not trying to launch and sync any accounts.
4) Now go to Calendar/Accounts, and add one account at a time. When I tried to add all of them, it hung again. My regular huge gmail file (a couple decades worth) loaded fine. That game me hope. My business account loaded fine, so 2 main accounts were working.
5) When I activate my Contacts calendar account (which syncs all the birthdays in contacts so it shows up in the calendar days), it hung and needed a force quit.
No idea how to fix that file, but for now I've just disabled that sync and my calendar app is working again.
Things that did not work that tech support tried with me:
-- disabling icloud sync
-- creating a test user and seeing if calendar app worked (it did)
-- logging in in safe mode a couple times
-- multiple reboots
-- finally, re-installing the OS, still did not work
Hope that helps
I have the same issue and its really annoying. So now I have to keep going to my phone to edit calendar entries or I have to go online to Google to create entries in Google Calendar... REALLY Apple??? Any solution to this mess?????
Variation on the theme: The Calendar loads and appears to be working, but I get bad results when I'm searching for a given entry (Pick a word and search for it). Some return as expected; many do not. My calendar is a 40+ year database that I mine (mined) all the time. I need this function for my business, and I'm now completely high-centered. I've been working with Apple Support and doing process of elimination efforts for two months. I think I'm one step away from "can't help you, your data is corrupted," which will make no sense (I can go to the date in the calendar and "see" the entry I'm searching on the screen ... The data is there).
I'm having the same issue on my Mac. Calendar invites for my Exchange email account that I accept don't appear in my Calendar. I have to quit the Calendar app and restart it. Edits to appointments in the same Exchange account get lost. Upgraded to Sequoia 2 days ago. Have shut down and restarted my Macbook twice since.
My issue is when I set up my exchange calendar on my new mac which had sequoia upgraded.
I added the exchange account, but in the sidebar (listing the accounts on calendar) there was no 'calendar' under Exchange and therefore I could not check any box to see the accounts. I tried to add it again and it said the account was already there. I deleted the account, added it anew but the same thing happened.
How can I fix this?
For me its not just iCal, I'm experiencing numerous issues! Worst update ever.
My Mac Mini does not freeze, but Calendar crashes every time I try to open it, since I updated to Sequoia... Very annoying!
Just putting my 2 cents in too. My iCal also wont open. Get a terminal error. There is a problem with the Sequia update. Apple please fix!
I am having the same issues. If I edit items or put new items in my calendar it freezes. This occurs on my Mac, but also in the calendar on my iPhone 14 Pro. Please fix asap!
You are lucky! Just tried that. Crash city. Apple Help!
Not only is mine locking up, but I don't have any of my calendar events on it. HELP! I live by my calendar. Thanks.
how exactly did you do this?
I can't get past the New Event field. It just freezes and none of the suggestions offered in this thread have helped. I am running 15.2. I sure hope Apple fixes this soon.
Same here. I had to create a new event on my iPhone instead. This is only started after the 15.2 update on my M2 Macbook.
Tried this - no joy.
First post here, because this is the most annoying thing. I'm using iCal for work and I can't use it really...

Why is my Calendar app not working after macOS Sequoia update?
