I have a 2020 iMac 27", for some reason it does not sync iCloud to Calendar. When I try to do it it gives me an alert that says "The Server responded with "400")
My iPhones (2), my wifes iPhone, and two iPads (2011,and iPad 7th gen) seem to sync fine.
What am I doing wrong?
iMac 27″, macOS 13.2
Try this... log poy og icloud then log back in.
Calendar 400 icloud error - Apple Community
Or...
iCloud Calendar sync error 400
It’s not always smooth sailing, though. Mac users who use iCloud on their machines can also encounter error number 400. If it’s the first time that you’re encountering this, know that the error indicates that it is unable to sync with your iCloud calendars, hindering you from using the Calendar app on your Mac.
This is typically the case if you open the Calendar app on your Mac and then see an error message that states “The request for account ‘iCloud’ failed.” The server responds with “400” to operation CalDAVUpdateShareesQueuableOperation, which means your Mac isn’t able to access the synced iCloud calendars on your account.
Learn how to fix this common error on macOS Sierra/Mac OS X 10.10 (Yosemite)/10.9/10.8/10.7 and lower, mostly through moving two of the calendar files from one folder to another on your Mac. Here are the steps:

Thank you for your reply.
This is the screen I got:
Sorry, not sure to where to go from here.

I think option #1 is to sign out of iCloud on my iMac then log back in?
Easy for you to say.
I'm guessing, on my iMac, go to System settings, scroll down to Internet Accounts.
Do I then;
or
2. DO I hit the delete account button?
Or is there another option I'm totally missing?

I figured out what you wanted me to do. Found the files. Threw them in the trash, dumped the trash and restarted.
Tried to resync the Calendar again. I get the following message.
Meanwhile I'll get the 64 GB of ram.
No idea if these are THE problem, but they are a problem...
Delete these files & restart...
/Library/LaunchAgents/com.google.keystone.xpcservice.plist
/Library/LaunchAgents/com.google.keystone.agent.plist
~/Library/LaunchAgents/com.adobe.ARM.***.plist
~ tilde indicates your user library folder
Apple hid the Users' Library folders...
Method 1:
1 From the Finder, select the Go menu at top of the screen, and choose Go to Folder.
2 In the window that opens, enter ~/Library, and click Go.
In addition, the computer is starved for RAM. I would recommend adding 2 x 8GB DIMMs of RAM which will increase the RAM to 24GB. Please only buy either Macsales.com or Crucial.com RAM. Why these vendors? Easy, their products are reasonably priced, great service, lifetime RAM guarantee, and they just work.

It looks like MacSales.com (OWC) has options for 4x16GB=64GB and 4x32GB=128GB, both of which would offer me much more than my current 8GB ram. I have no objection to going either way. Any plussed or minuses for going with either option? Thanks.
You're not scrolled down enough to see Launch Agents...
1 From the Finder, select the Go menu at top of the screen, and choose Go to Folder.
In the window that opens, enter ~/Library/LaunchAgents, and click Go.
& the other folder...
In the window that opens, enter /Library/LaunchAgents, and click Go.

OK I went to System Setting, then Internet Accounts and under iCloud, I hit the Delete Account. Scary!
I then, under Internet Accounts added in my iCloud again. For some reason it took several tries with my password to get things moving. At one point it even asked if I was connected to the internet. Several tries again.
I didn't think anything was happening. Then I went to Calendar, went to Views, and clicked on Refresh Calendars.
Got the clock timer spinning, then it worked! Calendar on my iMac synced with all my other calendars.
Thank you.
Whew, great to hear, good work, take care my friend! :)
Thank you for your reply. I have attached the EtreCheck report.
Too little information to help you out. Please start by attaching an EtreCheck report of your Mac.
I'd go with 64 GB of RAM
+1 on the RAM
Will do on the ram.
