Firstly PHP creates a unique identifier number (a random string of 32 hexadecimal number, e.g 3c7foj34c3jj973hjkop2fc937e3443) for an individual session.

PHPSESSID cookie passes that unique identification number to users’ browser to save that number.

A new file is created on the server with the same name of unique identification number with sess_ prefix (ie sess_3c7foj34c3jj973hjkop2fc937e3443.)

The browser sends that cookie to the server with each request.

If PHP gets that unique identification number from PHPSESSID cookie (on each request), then PHP searches in the temporary directory and compares that number to the file name. If both are the same, then it retrieves the existing session, otherwise it creates a new session for that user.

We need to be sure that PHP modules ext-mcrypt and ext-intl are loaded. PHP 7 that comes with MAMP already has them, we just need to be sure the OS uses the MAMP version.

Check the location of PHP :
which php

If the output is /usr/bin/php it means the default OSX PHP version is loaded and we need to change it.
Edit .bash_profile:
sudo nano ~/.bash_profile
or
sub ~/.bash_profile

The quote is created when you call Mage::getSingleton("checkout/session")->getQuote(). Check how the method Mage_Checkout_Model_Session::getQuote works. If there is a quote for the specified customer it returns it. If not, it creates one and returns it

is_active field is used in the following cases:

is_active is always 1 for cart/quote created by web user
is_active is always 0 for cart/quote created from admin
To load quote by Customer Id, is_active = 1 is taken into account
When quote is converted to order, is_active becomes 0
To restore the quote which is cleared by payment errors etc during checkout., make is_active = 1
When you create a quote via API, is_active is always 0

Magento provides a capability for adding options that aren't product attributes or product custom options. They are set on the product and quote items with the option code additional_options.

There are two steps you need to take, each can be handled via an event observer. If you want the additional options to carry through reordering, you will need also observe a third event.

Add options to quote item
The first step is to add the event observer to set the additional options on the loaded product before it is added to the cart. One option is to use the catalog_product_load_after event.

<catalog_product_load_after>
    <observers>
        <extra_options>
