Apple Intelligence is now available on iPhone, iPad, and Mac!
I can't seem to add a gmail inbox to Apple Mail. I go through the steps and when I confirm my 2 step verification with google it says "you are already signed in to that account". I'm sure I'm missing something simple but I don't know what.

Here are a couple of things to try.
Reboot your computer and see if the problem fixes itself..
If that doesn't fix the issue, please see if the problem still happens in Safe mode.
How to use safe mode on your Mac - Apple Support
Does the problem persist while in Safe mode? If not, then leave safe mode by restarting your Mac normally and re-evaluate the issue again after a normal reboot
If that doesn't work, trash the Mail preferences .plist file. It may have become corrupted.
Close the Mail app.
From Finder, option-click the Go menu > Library. Then double-click to open the Preferences folder.
Locate and delete the file "com.apple.mail.plist"
Logout of your User or restart the Mac and login again.
Check the Mail app and see if the new account has been created: Mail > Preferences > Accounts. If not, repeat the process for creating a Mail account... but first delete the currently created Gmail account in system Preferences > Internet Accounts.
In system prefs-->Internet accounts it shows it there but 'unable to verify account name or password' when I enter either my password for the account or an app password from google. In Mail-->Preferences--> under accounts there is no google account listed and if I try to add one it gives the above message 'you are already signed in."
Hello, Smorticula.
Maybe this will be of help. Mail User Guide for Mac - Apple Support:
You've clicked the disclosure triangle in Mail's mailbox list?
And the account is enabled in System Preferences > Internet Accounts?
Have you tried rebooting the computer?
I've gone through all those steps a number of times but always get the 'you are already signed in to that account' response, without Apple Mail adding an inbox.
