What is the method for missing sync smart uninstall Mac?

Hi guys. I hope all of you will be fine. I am using missing sync to connect with a PDA as well as cell phone to share photos, contacts and email from mobile to Mac computer. It sounds to be good but now I am unable how to uninstall it. I have tried by using deauthorize option but it is not working properly. Please tell me any method for missing sync smart uninstall mac easily. Any suggestion please.
