macOS wants access to your Google account

One final note, the options you select on your Mac mail setup (Sync contacts, calendar, email, notes) does not affect the access Mac OS requests from gmail. They seem to always ask for full access. I just authenticated with another gmail account that I only sync email, and it requested full access to everything (including chat), which isn't even an option.

This screenshot is the Mac OS authentication request when setting up just email syncing.

So if you want to use Mac mail with a gmail account and you on Mojave+, you need to allow full access and trust that Mac mail won't do anything its not supposed to do (which I do, more than other mac email clients). But Mac mail could be more selective of the access it is requesting.

Shahid, this is what access your Mac gets if you click yes.

It doesn't matter if you are only syncing calendars. Apple asks for it all, and there's no way to limit it. Unfortunate, but that's the way the chose to implement it. Hopefully they will change their policies if enough people complain.

It’s Google who is asking. Need to either accept all (no significant risk to you) or shift all your calendars from Google.com to iCloud.com.

That is what I did. The only problem as you probably know is accessing icloud calendar from android devices but it just needs an app and a one-time password. I prefer to trust my data to Apple rather than google.

The first request is for MacOS and safari not Mail.

From what I have gathered, Mojave is now using proper OAuth2 authentication, thus requiring the login via Safari, like if you were on your iOS app.

The level of access for deleting contacts, calendar, etc, are expected depending on the settings you configured in your Mail account setup. If you are not comfortable with these, the option is to use another mail client, or setup Gmail as a standard imap email account.

Gmail access to calendar, contacts, and mail all go through the same gmail authentication. So it is the same reason for why syncing a google calendar to mac calendar now requires Oauth2 authentication.

You’ve a good point. I’m guessing it’s because Mail (aka Internet) accounts by default access mail, calendar, contacts, notes, reminders then you untick them after signing in.

Circling back to my first point, If I still had a Google account it wouldn’t bother me how much access my own Mac had. It has a pass code that protects a lot more secrets than when Im having lunch. It’s me who has access not Apple.

Still you have a solution. Use T’bird and hope it is secure.

Nope, Google API requires MacOS to use Oauth2

So...its Google who is asking.

The number of very unhelpful (derogatory honestly) comments and statements here is beyond belief.

The bottom line is that when Apple releases an update to macOS they NEED to provide their loyal base details about what's IN the update! We WANT security updates, but if they keep surprising us with changes...we're going to be much LESS likely to take these updates.

I don't care about the details of the security fixes being included in the documentation, as Apple has always been cagy about detailing those. However, if you're going to introduce or include a NEW feature...they need to provide documentation so we are prepared to deal with the change.

For those who get blind sided by this issue the SOLUTION to is is to head over to System Preferences and uncheck the 'Safari Autofill' option under Touch ID as shown. Life returns to normal.

I just had the same thing happen and would really like an answer to this. The language sounds very heavy handed about what MacOS has the ability to do. Why is this necessary? Is there a work around?

its not google who is asking , its Mac OS . when i accepted google sent me a message that someone allowed Mac OS to connect to my google account and if it was me or not . I did but then i changed my mind and unauthorized them . when mac asks me to do that from now on i simply ignore it

Keep getting message that my google password is required...enter it in my internet accounts...when I do I get this ....macOS wants to access your Google Account

Its a requirement not a problem. Accept, or decline and go elsewhere.
