High Sierra gmail problem

Have you tried getting an application specific-password from gmail? I did it and it fixed everything (after a few tries...) It's still not working perfectly, but at least it downloads my mail and everything is there.

Thanks for the response. I actually found out just now that it is nothing wrong with my accounts. It is my workplace ethernet that caused the issue. This was the reason for it working on my laptop, with is only connected to the wireless workplace network, where everything is fine.

To sum up then, I have not problems with 2step login in with Google accounts and Apple mail. It works perfectly fine. It turns out som ports in the workplace network had been closed by network administrators...

I've had the same problem for months and even Apple was not able to fix it. Today i deleted my Gmail passwords from my Keychain and everything is working fine. I was able to install Gmail with no problems.

Open Keychain and search for com.apple.account.Google.auth-token. Once you find it make sure you get info and select the correct Gmail account that you are having problems with and deleted from the keychain.

You can now go ahead and install Gmail again.

Did you try allowing "less secure apps" in gmail's webmail? That solved the problem for me in Mail.

Firstly, what I learned from Google is that there is a daily data limit for gmail accessed through the IMAP protocol. IMAP protocol - which is what Apple Mail uses to access gmail accounts - asks for the entire gmail account to be updated both to the gmail server and to the computer/iOS device. I believe this means if you have a iCloud file structure into which you sort emails, IMAP is looking everywhere for changes and communicating that - it's not just communicating new data, according to the Google tech I spoke with. When the daily data limit is hit, the transfer slows waaaaay down or stops at least temporarily. Compounding the problem is that each device connecting via IMAP eats into that daily limit - the more devices you use via IMAP, the more compounding of the problem.

Partial Solution #1:

What I finally did was go into gmail console from web browser and create app passwords for my two iOS devices. Then used those passwords to set up my gmail account as an Exchange account, then deleted the old gmail account that uses IMAP protocol. It is not possible to set up gmail using exchange on MacOS. We'll see if this solves the problem. So far so good.

Partial Solution #2: What may have made the data limit visible was something that seems to have begun last month with the upgrade to 10.13.4 - a problem may have occurred with the mac mail program. The symptom of the problem was that every time I'd log onto my computer and open Mail, it would start downloading thousands of emails. While I couldn't be sure that these were only gmail emails, it is likely that they were, and each time it was eating into the data limit. I worked with a senior tech at apple and may have solved the problem by deleting one particular mail file in the user library - but I would suggest a call to apple for guidance on that.

So setting up my iOS devices using Exchange and by solving the problem with Mac Mail, I think I brought my daily gmail data use way way down and so hopefully will not see the problem again.

See this article If Mail on your Mac keeps asking for your password - Apple Support

I signed out of my iCloud account, restarted, and signed back in and things seem to be back to normal. Very spooky stuff at work here.

I have the same problem. I solved it temporary by switch on "Allow less secure apps:" on my google account.

Mail connect to gmail account for a few minutes, but after that the connection drops again.

It is something between Apple and Google.

I have this problem too.

I can sign in to the app store. I can get an apple ID verification code (multiple times) but there is no place to type it.

Two choices only:

1. Username and password

2. I forgot

no place for verification code.

and i did not forget my username and password.

I have exactly the same problem. Gmail works fine in Safari as webmail but not with Mail, same response as you are getting. The password used by Keychain logs me into Gmail fine in Safari but not in Mail. It also works fine with older versions of OSMac and on other devices. WHAT have you done Apple? One of the most popular email services and you've screwed it! Get your finger out and get it sorted.

I am having this issue with all accounts through mail as well as through iCloud. All gmail accounts prompt me to enter my password. When I enter the correct password, the screen goes gray and does nothing. Outlook prompts a different error:

"Connections to host outlook.office365.com on the default ports failed."

These issues appear to have started randomly on Friday but maybe there was a small update I am not remembering.

More concerning, perhaps, is the fact that my computer also prevents me from logging in to iCloud. Similar phenomenon - when I enter the correct password, the verification applet becomes unresponsive or says "An unknown error occurred".

The big problem here is that now I can't access the app store to receive updates!

I see that some people have had luck with removing and re-adding accounts. This is not a fix! It's a work-around. So...where is the fix?

I started having the same problem today. I can login fine on web gmail but now when I start apple mail, it says login failed, and then when I type in the correct password, the screen goes gray and nothing happens.

I have the same issues now too. Continually prompted to login to icloud - won't connect. Google Calendar won't connect, when enter password and verification code it just grey's out. Until I found this thread I thought I had been hacked in some way to capture all my passwords.

logged out of icould on imessage, can't log back in. Guess I will keep an eye on this thread for a solution.

Frustration.

I too just noticed I was having this issue last week (possibly Friday). I've deleted both my gmail accounts and tried to delete iCloud from system preferences but message for iCloud informed me there was an issue and for me to turn off all iCloud services.

So I tried to add back my gmail accounts but after clicking on "Done" the program just sits/hangs there. Only thing I can really do is select the items or click on "cancel".

This is very frustrating as its coming up on my exams and I really would like to use Mail instead of the web interface.
