Laravel - Could not find driver sqlsrv on mac

I'm working in a OS X and i install a virtual box with sql server, i set the network virtual box to connect.

In mac i install the freetds and if i do this command it connect:

The laravel connection is this:

'dbname' => [
        'driver' => 'sqlsrv',
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '2222'),
        'database' => env('DB_DATABASE', 'dbname'),
        'username' => env('DB_USERNAME', 'xpto'),
        'password' => env('DB_PASSWORD', 'xpto1234'),
        'charset' => 'utf8',
        'prefix' => '',
    ],

When i run laravel i have the error could not find driver.

In phpinfo() i have mssql extension but don't have sqlsrv.

What is the problem?

Thank you.
