I had been struggling with this for sometime. I wanted to create a USB installer for Mavericks and was not able to get thru’ a step where I had to show hidden files and folders.
In Windows OS, it’s a simple step which is available graphically to either show or hide hidden files and folders. But in Mac OS X, for some reason, this has to be achieved by typing a command on Terminal. Following is the command that is required to enable showing hidden files and folders:
defaults write com.apple.finder AppleShowAllFiles TRUE killall Finder
So, those who struggle to get it done, above is your key to unlock this.
