They are part of the file quarantine feature that was added in 10.5:įile Quarantine is a new feature in Leopard designed to protect users from trojan horse attacks. The extended attributes probably have nothing to do with the issues you are having with Apache.

What would cause the operating system to quarantine the folder? Was it the attempted access from another machine, or something to do with Wordpress's configuration? Listing the folder in question in the Terminal showed me that the extended attribute had been applied to it and to all files contained within. From that point forward, the entire folder containing the Wordpress site disappeared from the index page at foo.local / my-computers-hostname.local, and any attempts to access it by URL were met with a 403 - Authorization Refused error from the webserver. When I attempted to change its URL setting to my-computers-hostname.local, something very strange happened: I received an authorization error when attempting to save the change. I was able to see the root index of ~/Sites from the phone by surfing to my-computers-hostname.local, but couldn't access the Wordpress site, as it had been set up to believe its address was foo.local, and therefore had hardcoded references to that URL in its database. Then, I tried to access the site from my iPhone. This was working fine, I'd mapped foo.local to 127.0.0.1 in my hosts file and was accessing the site from there on my laptop. I had a folder under ~/Sites, let's call it Foo, from which I was sharing a Wordpress site-in-development via Apache.
