quarantined file issues in Mavericks OSX

Ok, so ever since I upgraded to Mavericks from Mountain Lion, I’ve had crazy issues dealing with font files that I’ve downloaded. At first, I thought it might be some sort of font issue with Mavericks, but it turns out it’s a quarantine issue with downloaded files.

For a bit now, OSX quarantines files that are downloaded. It’s a nice security feature, but dang, it’s really messing me up :/ I’m not sure yet why my box is behaving this way. I’m sure there’d be massive outcry if this were a rampant issue.

When a file is downloaded, some extra meta is added to it. You can tell from the command line as the permissions look something like this when you list all aka ‘ls -la’ …

The work around I’ve pieced together that I have to do each time I download a zip file is to unpack it, then run xattr on it to remove the quarantine flag. Here’s an example of a style.css file that I ran this on to allow scripts on my box to see the file.


xattr -d -r com.apple.quarantine style.css

or

xattr -dr com.apple.quarantine style.css

What should happen is when I click to unzip the zip file, I should get a GUI alert that asks me if I really want to open this file from the internet. Sadly, it’s not happening on my box.

Anyway, hope this helps the random person out there searching for a possible solution.

It would be helpful to let you know how to actually find the bit of data to remove. Above you see com.app.quarantine. That’s the metadata you need to remove. To find it simply type…


xattr somefilename

That’ll output a string which you’d put in place of ‘com.apple.quarantine’ as seen above.
