Privacy Settings for MacOS
In order for Caption.Ed to work with MacOS, you must enable permissions for it to work. If you don't allow these permissions, then Caption.Ed may not work as intended for you.
The options you need to ensure that have been enabled are;
Full Disk Access
Microphone Access
Accessibility Access
You can do this by clicking on the Apple logo, and then choosing System Settings. From here, click on Privacy & Security in the left-hand sidebar.
