通过composer在mac os上安装laravel

I need to use lavarel on mac os. I first installed MAMP. After that, following instructions on laravel.com, I installed composer globally via homebrew. Now, when I change my directory to /Applications/ MAMP/htdocs and try composer create-project laravel/laravel myname on the terminal, nothing happens even after half an hour. I also tried downloading lavarel-master manually,putting the content in htdocs and composer install .Again nothing in .5 hour. I have done composer self-update and checked composer diag and all is OK. Upon trying which php ,i get /Applications/MAMP/bin/php/php5.5.10/bin/php I also restarted mac and tried the commands again,but same result.

Please help ,I am new to php and don't know how to proceed.

PS:Upon trying composer install in laravel master directory the following appears on terminal:Loading composer repositories with package information Installing dependencies (including require-dev) and then only the cursor blinks, nothing happening. Is that a trouble with my composer or laravel installation?
