Is there a free wordpress client for mac? I am a new Mac user and a casual blogger. All the applications listed are expensive, as I am a student. I am scared to set up Wordpress natively on my MacBook Air. Something like the wordpress app on android?
If you are a casual blogger then your best bet is to use the web client built into your Wordpress installation, just log in to your blog and away you go. 

And I believe that the Wordpress app for IOS is free...
