We're a little Basecamp-crazy over here at Social Signal, and a lot RSS-crazy. So the fact that Basecamp spits out a handy RSS feed that updates you when your projects to much as twitch is, to us, a Good Thing.

But I've never been able to make reading the Basecamp feed a frictionless part of my daily workflow. That's why I was intrigued by one of the new features in the latest version of the Macintosh operation system, OS X 10.5 (known to its friends and marketers as Leopard).

The new version of Mail included with Leopard allows you to subscribe to an RSS feed right alongside your email messages. Which looks like a perfect solution...

...until you try adding the Basecamp feed.

Basecamp, being a secure site where you can plan projects without worrying that the world is peering over your shoulder, very sensibly password-protects its RSS feeds. Mail, unfortunately, is baffled by feeds that require authentication. (And what's worse, it doesn't tell you that's what's the matter.)

So what's the solution? Thanks to the fertile mind of one Kanuck54, a user on Apple's support forums, there's an easy way to get around Mail's minor failing:

The trick I found is getting the authentication information into your keychain.

You can open Keychain Access and add it yourself, but the easiest way is to set Safari as your default RSS reader, open the RSS feed with Safari, and when you enter the username and password tell it to add it to your keychain.

Then go ahead and add the feed to Mail (note the link in Safari to do this doesn't work), and give it permanent access to the keychain entry. Everything should now be good to go.

I tried this without setting Safari as my default RSS reader; the tip worked fine.

And by the way, Safari turns out to be a bit of a Rosetta Stone (that's this kind of Rosetta, not that kind of Rosetta) when it comes to figuring out how to make Mail jump through fiery hoops while juggling kittens and singing The Girl from Ipanema.
