Activating the microphone using a Mac

We all know that to use your microphone with a PC in a Centra session you must hold down the CTRL (Control) key while speaking. When you press the CTRL key, your microphone icon to the left of your name turns yellow.

This key-command on a Mac computer is different. To use your microphone while on a Mac computer you will need to press the "Option" key (the one that is two keys to the left of the space bar). Pressing this key will activate your microphone (and turn your microphone icon yellow) and allow you participate in the session.
