I’ve mentioned before how much I dislike MacOSX’s metadata files and how it writes them everywhere by default, including to almost every single directory users touch on servers I manage. It’s my sincere wish Apple would address this themselves, but given that the problem has existed for years it seems unlikely. Meanwhile, enter another solution – BlueHarvest. It’s a control panel for OSX which allows you to disable the creation of DS_Store files on a per location basis, remove existing files, and change the default permission profiles assigned to them. Do the world’s networks a favor, mac users, and install this and turn of creation of metadata files for anything but the volumes you own, it won’t cost you anything and the world’s network admins will thank you.
