Unable to install drush on mac 10.9.2

Question

Lately I was trying to install drush for the first time. This is what I did..

• Installed the drush tool manually
• Extracted and renamed the tool to /Library/Drush
• Gave the /Library/Drush/drush tool execution permissions.
• Created an alias for drush in ~/.bashrc
• Tried to bash drush by entering the alias drush, that's when I got the first problem: Unable to load autoload.php. Drush now requires Composer in order to install its dependencies and autoload classes. Please see README.md
• After lots of searching I tried way to many things:
  • which drush doesn't return anything.
  • Installing the composer (at /usr/local/bin/composer) results in this The requested package drush/drush 1.0.0 could not be found problem when executing composer global require drush/drush:dev-master

Help would be appreciated, because I don't know what I could do to make it work.

Thank you in advance, `F.

I have encountered the same error while installing the drush on MAC, I have tried the following and that worked for me:

composer self-update
ln -s /path/to/drush/drush /usr/bin/drush

I have downloaded the Drush from this git repository: https://github.com/drush-ops/drush

And followed the method described here for installing the Drush on MAC: https://www.drupal.org/node/1674222
