I’m currently working on a project where we’re developing directly on the development server. It’s not my preference to develop this way, but alas it’s necessary for reasons I won’t go into.
I work on a MacBook Pro running OS X 10.8 (Mountain Lion). One problem we’re running into is OS X loves to continually write the .DS_Store files to each folder I view. And I view most every folder on a daily basis. Needless to say it writes a lot of them.
I searched around and found that you can disable this for network resources. Simply open terminal and execute the following command. Make sure to log out or restart your machine for the change to take effect.
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
