High Sierra google calendar with app password not working with calendar app

I found a workaround. You can add your Google Calendar separately to your internet accounts by adding a CalDAV account and filling out the advanced options info. Overall, you need to:

• Generate app specific password on google
• System Preferences -> Internet Accounts -> Add CalDAV account
• Set account type to Advanced
• Set user name to google account (yourusername@gmail.com)
• Set password to app specific password previously generated
• Set server address to: https://calendar.google.com
• Set server path to: /calendar/dav/yourusername@gmail.com/user/
• Set port to: 443
• Put a checkmark in: Use SSL
• Leave "Use Kerberos" unchecked
• Sign in

This worked for me on High Sierra 10.13.6. Learned this on Reddit here - https://www.reddit.com/r/techsupport/comments/uoui46/unable_to_set_up_caldav_with_apple_calendar_using/

Hi all-- I am dealing with the same issue: Using High Sierra (for various reasons) and cannot add Gmail or Google Calendar to Apple Mail or Apple Calendar. Thiis is a recent issue and only arose after a recent password change. Apparently Apple no longer considers the Google app ecosystem "secure" in High Sierra.

The Gmail issue is solvable by generating a Google "app password" in your Google account. First you have to create "2 step authorization" which will then allow the option to generate a special "app password." Then you create the new mail account using "Other mail account" instead of the Google mail option.

My issue is that using that method only shows the ability to sync MAIL and NOTES. Not Calendar (and a 4th option I forget...). See my screen shot. Then, if I try to add a CalDav Calendar account in Calendar it fails as per the above user.Anybody found a workaround?

Having the same issue myself. Just started suddenly the other day.

Adding some screenshots and following, thanks

You've tried all these?

Mac's Mail App is not as modern as iOS's Mail app, Many eMail providers now require a separate App Password different from your eMail password…

If it's an IMAP account, delete it in Sys Prefs Internet Accounts then use "Other" instead of gMail choice to add it.

Most likely biggest factor is using Other in Mail setup, then using a Browser that doesn’t have gMail PW stored init to get the App PW.

It might just need an App Password separate from the gMail password…

Yahoo App password…

Generate and manage third-party app passwords

Some older, third-party email apps (that do not use our Yahoo branded sign in page) require you to enter a single password for login credentials. To access your Yahoo Mail account on these apps, you'll need to generate and use an app password. An app password is a long, randomly generated code that gives a non-Yahoo app permission to access your Yahoo account. You’ll only need to provide this code once to sign in to your third-party email app.

Most likely biggest factor is using Other in Mail setup, then using a Browser that doesn’t have Yahoo PW stored init to get the App PW.

Using app passwords with apps that don't support two-step verification (microsoft.com)

What about application passwords? Will that keep working?

If application passwords are being used for MFA (Multi Factor Authentication) along with basic auth as another auth mechanism, then when basic authentication is disabled, app passwords used for MFA will stop working too.

Where can I find more information?

There are several resources that we wanted to provide here as additional reading:

• Basic Authentication Deprecation in Exchange Online – September 2022 Update – this is a comprehensive post containing more information about this effort.
• Deprecation of Basic authentication in Exchange Online – our official documentation related to this effort, with links to much more information and guidance.

Actually it's google not caring for the lack of security in older versions of Mac Mail, and not just google, most every eMail supplier. :)

And since Mail & Safari are both tied to the OS version, they get outdated in short order nowadays.

Here's the Choices in my 10.13.6 Internet Accounts...

Bit of a pain, but...

To find out if it's system wide or user specific, try this...

Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

Does it work in the new account?

Good afternoon gbeekman,

Welcome to the Apple Support Communities!

It sounds like you are having issues with Google Calendar and Mail. If you are able to upgrade your macOS operating system, that would most likely resolve your issues. macOS 13.3 was released today, Mar 27, 2023. Here is the link to Google support for help with their apps:

Google Calendar Help

Set up Gmail with a third-party email client

Take care.

I'm having the same issues for one of my clients, who is using a mac on their old laptop. Google isn't allowing the login, been using 2-factor auth and app passwords, and it's still not allowing me to login. There was an option to configure "manually" but I'm not sure what to put in under "Server Options"

Is there no solution besides updating ? Because my 2012 macbook cannot go beyond high sierra, but still works wonderfully otherwise……

No

Same problem. Need a little help.

Thanks for the info. :)

This worked for me. Thank you!
