Fixing Microphone Permissions for Safari on Desktop
If you didn't receive a pop-up or see the Microphone permission required message, you will need to reset Safari's permissions for Caption.Ed.
In the top navigation bar, next to the Apple logo, click on Safari and then choose Settings.
Then, choose Websites in the top bar, and then select Microphone. You will then see a list of currently opened websites within Safari and a drop-down menu next to the Caption.Ed URL that says "Deny". Click on this drop-down menu and change this from "Deny" to "Allow".
Once you have changed this to Allow, you can close this Settings window, refresh Safari and then you can choose which Microphone you want to capture from.
