Installing Drush on Mac I am installing Drush on my Mac following the instructions I found on https://linode.com/docs/websites/cms/drush-drupal/.

Everything works perfect, but I got stuck at the end while creating the symbolic link. Please find the error below.

Mudasirs-iMac:/ mudasir$ sudo ln -s /usr/local/src/drush/drush /usr/bin/drush

ln: /usr/bin/drush: Operation not permitted
You can't write to /usr/bin on OSX (since Yosemite).

Add your symlink to /usr/local/bin instead, and make sure that's in your path.

ln -s /usr/local/src/drush/drush /usr/local/bin/drush
