Not able to get OAuth token for Magento Rest Client on OS X -

I am using Magento version 1.9.1.0 and using the Oath integration using the Metasto Rest API. I have consumer keys and consumer secrets now want to get an othe token for the rest of the API usage. I have followed it

In this, we need oath_signature and timestamp, when we make a consumer on the admin panel, we do not get it. Now how can we get an Oeth Token only with consumer key and consumer secret?

I think you should follow the wishes blog. Hope you get some ideas.
