Gmail not working

Open Account. Under Advanced tab uncheck "Use IDLE command..."

Let me know if this helps.

I checked and unchecked it like 10 times before.

I don't have two step verification set on gmail.

I deleted and set up all internet accounts (including iCloud, gmail) two times already. Tried to set it up as Gmail and also manually inserted the servers.

Tried different intervals of checking new mail like you recommended.

Tried to disconnect Wi-fi and connect iMac directly via cable.

I've read all threads about Mail problems. Some people have the same problem, there are many advices - none of them help so far. My wife's mail on MacBook Air and my friend's Mail on iMac work well both with gmail accounts. The same settings.

Thanks anyway for your concerns!

Eliminate Mail by testing in Postbox and MailMate. Both have demos.

Setup in MailMate is super easy since it imports your account info from Mail. MailMate supports IMAP only.

Postbox has a nice interface and includes features like adding DropBox links in a message.

Same with me. This Mail JUST doesnt work. I did every possible thing.

But the error is the same! And I am not logged in from ANY OTHER account / device.

There may be a problem with the mail server or network. Verify the settings for account “Google” or try again.

The server returned the error: Mail was unable to log in to the IMAP server “imap.gmail.com” using “Password” authentication. Verify that your account settings are correct.

The server returned the error: Too many simultaneous connections. (Failure)

Same here from a long long time... and not only this. Mail prevents the shut down of Macbook. I have to wait like 40/60 seconds because Mail won't close.

Did you ever remove the Gmail account then add it back?

Not what is happening

on my older mac book pro no problems and it runs 10.9.2 also it is a problem unique to my new machine

Go to Mail > Preferences > General > Check for new messages: select 15 minutes and see if that helps.

Yeah, I think that did the trick. Thanks! Gmail can't handle email checks every minute.

We can put a man on the moon, but not email checks every minute....

Glad to hear it worked. Please mark my reply as answer so other that are searching for a fix can find the solution.

Trying to do so, but the only option I have is to "like" your answer.

This helped.
