If you're having a serious issue getting your website running. Start with the .htaccess file, as this does fix many issues.
Before you go looking for it in the installation folder of your software package, you're not going to find it so easily. This is because OS X treats all files with the dot in front of it (.filename), as a system-only file and will make it invisible, so you don't muck around with it.
1. To get OS X to remove the hidden bit, run the following commands in Terminal.app:
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder
(*** DANGER - ALL invisible system-only files will now appear. DO NOT edit, move, copy, or otherwise tamper with any of them, as you may render your machine unusable, or worse, causing a KERNEL PANIC ***)
2. Go to your Dolphin installation folder and the .htaccess will appear. Move this over to the root directory of your Dolphin installation.
3. After you've copied it over, you will need to reverse the hidden bit back on by issuing the reversing commands:
defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder
All hidden files will be returned back to their original state, and you're good to go!
Hope this helps my fellow Mac/*nix users, after trying in vain looking for a file the system was naturally protecting, by hiding it.
Please let me know if this worked for you, or if you have any other Mac/OS X related issues I can help with.
