When you click URLs does the wrong browser launch? Well, you can change your default web browser right from Safari. Press CMD+, to get to Safari’s preferences. In the General pane, click the Default web browser drop-down menu, and then select your browser of choice.
But what about your default mail client? It’s just as easy. In Mail.app, press CMD+, to bring up the preferences. In the General pane, click the Default email reader drop-down menu, and then select your mail client of choice.
