When developing in a Mac OS X environment you quite often find yourself wondering why some files doesn’t show up in Finder. If you’re developing for WordPress, you might wonder where your .htaccess file is. This is because Mac OS X hides Unix files.
To show hidden files in Finder, open up the Terminal and paste the following code
defaults write com.apple.Finder AppleShowAllFiles YES
For it to have effect you need to restart Finder. To reset Finder, hold the Option key, click the Finder icon in the dock and hold it until the menu pops up and choose “Restart”.
