macOS/iOS Safari – Can’t enable microphone

Safari 15 will not share your microphone with the session, and will eventually suggest you quit and re-join.

When you switch your microphone on, it won’t respond. After several seconds, Collaborate will prompt you to reload the session via a message at the top of the screen. Doing so will have no effect on your microphone.

Alternatively, on macOS, you can use another browser.
