Mac Mail App Broken for Some Gmail Users in macOS Mojave 10.14.4

That’s not a bug. That’s a feature.

[edit] Google has now fixed the issue so the following workaround is no longer necessary.

i'd definitely be interested, i sometimes use charles.

Okay, so I've tried to make this as easy as possible. We're going to use Charles to rewrite a response from google to include the email address which is for some reason missing in google's own response. This is a one time setup only needed for verification.
[LIST=1]
* Download, install and run Charles ('https://www.charlesproxy.com/download/latest-release/').
* If this is your first time using Charles it should prompt you to authorize automatic proxy configuration. Do this. (Otherwise just make sure the macOS proxy is enabled and working)
* From the Help menu choose SSL Proxying > Install Charles Root Certificate.
* Once the certificate is installed, find it in your keychain (type Charles into the search), open it, expand the Trust section and set to Always Trust. You will be prompted for your password when closing it.
* Back in Charles, from the Proxy menu choose SSL Proxying Settings.
* Add a new location with Host: people.googleapis.com.
* From the Tools menu choose Rewrite and click the Add button.
* Add a new location with Host: people.googleapis.com.
* Add a new action with the following details...

* Type: Body
* Where: Response
* Replace Value: {"names":[{"metadata":{"primary":true},"displayName":"Your Name"}],"emailAddresses":[{"value":"your@email"}]}
* (Make sure you put in your name and email address)

* Once you save this, we're all set. Go to your system Internet Accounts or (Mail) and authorize your account.
* If everything thing is working, you can quit Charles and feel free to delete the certificate from Keychain.

I have a fix! Use iCloud mail :)

Eh, it’s whatever. I’m not worried. Haven’t kept anything of importance in my gmail account in a while, just annoying subscriptions.

I would have expected an update from Apple by now. Surely this is an easy fix. Do they think users can just wait days because Gmail is accessible other ways?

There's no such thing as an easy fix. This is probably broken because someone thought something else was easy to fix and this broke as a result.

Any patch needs to be QA'd, and that will take a cycle or two. I just wish there was a better way for Apple to get the word out to people that there are known issues to be aware of so people didn't update and get hit with this in the mean time.

Thanks to MR for posting it. [s]At least I know I'm not crazy.[/s] At least this can't be taken as further evidence that I'm crazy.

We use GSuite on the company and a this sucks
