I have just installed Drupal onto my Yosemite box. OS X 10.10.3, and there don't seem to be any particular gotcha's, apart from the old documentation on the Drupal site referring to older versions of the OS X platform. If you are on Yosemite - ignore them if you have your own Apache installation working.
The version of Apache that comes with OSX - Yosemite is more trouble than it's worth, so I installed my own. My own MySQL and PHP as well.
this is getting irritating and trust me, I've searched and tried everything I have found to solve this problem but no luck so far.
The problem is that when I try to install Drupal 7.37 on a remote server (which I have no control of), I get an internal server error. I have moved Drupal to the server via FTP, like so many times before, but when I go to the url the error comes up.
