Jitsi Meet FAQ 0. Could I have a practice session before my talk? Yes. Please write to Gianni Salme, Giovanni.Salme@roma1.infn.it to arrange with him a brief trial session on https://meet.jit.si/ILCACseminar 1. How do I avoid mic feedback using Mac? Identify the source of interfering sound, perhaps an additional monitor speaker or the like. Turn it off, so that beats with your computer speaker will be eliminated. You can turn off additional speakers brutally by working in the stand-alone mode on your computer. 2. How do I share screens on Mac? Go to security & privacy --> screen recording, and check the box corresponding to the browser you are going to use. 3. Can my face be visible when I share my screen or application? Yes. However, everyone has only one screen available. When you use it to share a screen or application, the shared content appears, but the camera goes into a standby mode. When you click on your camera icon again, it starts working and your face, or what you show your camera, appears in the lower right corner of the shared screen. The image is small, but clearly visible.
