I like Mavericks. I love the improvements to Finder, with tabbed browsing and tags. And pretty much everything else. But it raped one of my favorite apps, Mail.
It was discovered pretty early after the release that Apple had changed the way it was handling Gmail accounts. And this resulted in crappy performance and very slow message delivery. News Flash: Apple hates Google now.
Granted, they realized they messed up and released an update shortly thereafter, but it still isn’t the same. It is no where near as responsive as it used to be.
A few days ago, a buddy of mine told me he was worried that Mac Mail was becoming unusable. He mentioned the slow delivery of messages. I thought about it, and then I started to notice the same thing.
I am a devout Gmail user. For me there is no better email service. But, I like the functionality that a client gives me for working in other applications. And you you work in the Apple Eco System, Mail is a must use app. But it’s crap right now and I hope they give it some love very soon.
But back to the matter at hand! My buddy and I had the idea of removing the accounts from our Mail App and starting from scratch. And that is what you have to do, but you also have to take one, more drastic step.
Go into your MAC Library (if you don’t know how to get there, from FINDER>GO and hold down the OPTION key, Library shows up) and delete the IMAP folders for all your Gmail accounts. Go back to Settings, and add them again. VIOLA! Mail is fixed. Messages come in again at the speed of light.
It will take some time to download all your messages again, but for now this seems to fix the issue.
