I am new to the Mac world. In general, how do I uninstall software on a Mac? I recently installed some software for the purpose of preparing to install an upgrade version, both of which had been on my old PC. Now I see that the upgrade works only on Windows even though the older version could be installed on a Mac. Now I want to remove the older version from my Mac, and I don't see how. Specifically, the old version is Dreamweaver MX and the new is Dreamweaver CS4.
