Why can't I open .zip files?
It seems any time I attempt to download .zip or .dmg files the Archive Utility agent is unable to properly decompress said files. Once the download is complete and I attempt to open the .zip file, an error message pops up: "Error 01: Operation Not Permitted". I've tried resetting Safari/emptying the cache and made sure I was allowed to read and write files, but I still receive the same error message. I've had my Macbook Pro for about three months now, am unsure what to do next.
MacBook Pro, Mac OS X (10.6.7)
