How do I deactivate the plugin on my local dev site if I want to install live

I am testing this plugin for my client on my local mac. Once I finish developing locally, I will push to my test server for his approval. Once client has approved I will install on his server. How do I deactivate and reactivate the plugin each time I move it? Do I just deactivate the plugin in the Wordpress Dashboard? Or do I need to contact you?
